Rise and Early Development of Islam


Islam is one of the three major religions in the world that professes the belief in a single God. In Arabic language, the word Islam means surrender or submission to the will of Gods. A follower of Islam is called a Muslim meaning to surrender to God. The Arabic word for God is Allah refers to the same God that is worshipped by the Jews and Christians. Islam's teaching of God is that there is only one all-powerful, all-knowing God and that this God created the universe. This rigorous type of belief in a single God as well as Islamic teachings that all Muslims are equal before God provides for a sense of loyalty to God that goes beyond class, race, nationality and even differences in religious practices. So all Muslims belong to one community regardless of their ethnic or national background.


After the rise of Islam in the 7th century, it spread its origins into Syria, Egypt, North Africa, and Spain to the west, and into Persia, India, and by the end of the 10th century also to the east. In the following centuries, Islam also spread into Anatolia and the Balkans to the north and Africa to the south. There are about one million Muslim followers on all five continents and is considered to be the fastest growing religion in the world.


One of the reasons that the Muslim community has grown is because of its openness to new members. Children that are born to Muslim parents are automatically considered to be Muslim. A Muslim can convert to Islam at anytime by declaring they to be a Muslim. A person's declaration that they are Muslim is evidence enough of the conversion and doesn't need to be confirmed by anyone else or even by the religious authorities.

Muhammad, the founding prophet of Islam, was born in Mecca around ad 570. His uncle, who had religious contacts within the main Quraysh tribe of Mecca, raised him. He got married at the age of 5 to a wealthily woman of 40, Khadija. At the age of 40, Muhammad had his first experience of Islam after retreating to hills outside of Mecca. The angel, Gabriel had come to Muhammad in a dream. Gabriel told Muhammad that God had chosen him to be a messenger for him and also told him of the first revelation of God. After awaking from the dream, Muhammad was terrified and shaken and so returned home. His wife was the first person to hear his message and she converted to Islam. He received several more additional revelations, which caused him to start preaching the new religion. At first the Meccans ignored Muhammad's message and made fun of him. When more and more people started accepting Muhammad's message, the Meccans only became more aggressive. At first the Meccans tried to persuade Muhammad away from this new religion and when that failed they started persecuting his followers and when that still didn't work the Meccans persecuted Muhammad. During this time, a couple of tribes from the city of Yathrib invited Muhammad to live there. The leaders of the tribe invited Muhammad to settle disputes as an impartial religious authority and in return for Muhammad doing this the leaders promised to accept Muhammad as a prophet and support his new religion. This new religion taught that there was one God and Muhammad was considered to be the last of the prophets and messengers. God had sent various codes through his messengers, or systems of laws to live by, culminating in the Qur'an, which is the holy book of Islam. The messengers were mortal men and included men such as Moses. Muhammad is portrayed in the Qur'an as a person who makes mistakes but does not sin against God. God corrected Muhammad's mistakes and errors and judgments, so that his life could serve as an example for other Muslims to follow. The emphasis that is put on Muhammad's humanity serves as a reminder that other humans can also strive to lead a good life.


Islam taught that the Christian Bible along with the Qur'an were holy books. There were two earlier scriptures that had been altered over time from their original forms given by God but the Qur'an would remain perfect, preserved by God from being altered. This new law also taught that the God of Islam had provided humanity with a means to be able to tell good from evil. So on the Day of Judgment people would be held accountable for their actions.


But the teachings of Muhammad drew a lot of hostility and severe opposition. He ended up leaving Mecca and sought refuge in the city of Yathrib. The name of the city Yathrib was changed to Medina (meaning the city) upon Muhammad's arrival. The date of his immigration was later set as the beginning of the 1-month lunar Islamic calendar.


During the ten years that Muhammad spent in Islam before arriving in Medina he had laid the foundation for the ideal Islamic state. A group of committed Muslims was established and a community life was ordered per the requirements of the new religion. From this came about the five pillars of Islam which is the essential religious duties that is required of every capable adult Muslim. Some of the five pillars are described in the book Qur'an and were already being practiced during the lifetime of Muhammad. The five pillars are the profession of faith (shahada), prayer (salat), almsgiving (zakat), fasting (sawm) and pilgrimage (hajj). The five pillars are the most central rituals of Islam and constitute the practices of the Islamic faith. Some Muslims also believe that there is a sixth pillar, which is Jihad and has been understood as holy war. But the word Jihad in Arabic means to struggle in order to please God. According to Islam faith this effort can either be collective or individual and can also apply to leading a good life such as; helping out other Muslims whether through charity, education or by other means.


The first of the five pillars is the profession of the Muslim faith. The focus of Islamic piety is Allah, the all-powering, all knowing and above all, the all-merciful God. Allah is believed to have brought the world to its being and will sustain it until its end. If they obey the commands of God then they are expressing their recognition of and gratitude for the wisdom of creation and to live in harmony with the world. The profession of the Muslim of faith is all it takes to become Muslim. Several times a day and when they say their daily prayers the profession of the Muslim faith are repeated constantly. The words that are said to profess the faith of Muslim are as follows "I bear witness that there is no god but Allah and the Muhammad is his prophet." These words can be said anywhere at anytime. When an individual professes the Muslim faith then this is considered to be enough evidence to be a Muslim and cannot be challenged by any other Muslims.


The second pillar is the religious duty to say five daily prayers. All adult Muslims are required to say five daily prayers, followed by a ritual cleansing of the body at different times during the day. Muslims used to have to face Jerusalem during these prayers but this changed during Muhammad's time and then they had to face the Kaaba, an ancient shrine in the city of Mecca.


There are really no set descriptions for the five prayers only that the example was set by Muhammad which are later preserved in Islamic traditions. The five daily prayers are required to be performed at certain times of the day dawn, noon, midafternoon, sunset and evening. The prayers that are said at dawn, noon and sunset prayers do not begin at these precise times but a short time after.


The prayer is made up of a sequence of units that are called bowings. During each of these bowings, the person praying has to stand, bow, kneel and prostrate while reciting verses from the Qur'an along with other types of prayer. These prayers are repeated four times each time the person has to pray at the set times during the day except the prayer is only repeated three times during sunset and twice at dawn. A group prayer is required at noon on Fridays. The Friday group prayer is led by a prayer leader and differs from the other prayers that are said at noon during the week. The prayer is always concluded with the profession of the Muslim faith followed by the greeting "may the peace, mercy, and blessings of God be upon you." The purpose of the daily prayer is communication with God in order to maintain the presence of God in their daily lives. It also provides discipline that structures the day and fosters a sense of community and shared identity among the Muslim people.


The third pillar is Almsgiving. This is a religious obligation and expresses a devotion to God. It tries to provide for the poorer sections of the community and offers a means for Muslim people to purify their wealth to attain salvation. Islamic traditions along with the Qu'ran strongly encourages charity and reminds the Muslim's of their moral obligation to the poor, orphans and widows. The Qu'ran does however distinguish between general, voluntarily giving and the obligation to give money or produce. It identifies specific ways that this tax is allowed to be spent which includes spending the money on the poor and needy, on those who collect and distribute the Almsgiving, those who the Muslims are trying to convert over to Muslim, travelers, and on the cause of God. The Qu'ran doesn't go into detail about what kinds of things are subject to the Almsgiving tax or even the precise share of income or property that should be paid. An example is, one-fortieth of assets that are accumulated during the year (to include gold and silver as well as money) is payable at the end of the year or one-tenth of the harvest of the land is payable at harvesting time. If the Muslims have animals such as cattle or camels would be subject to a more complex tax depending on the animal such as age of the animal, number of animals, and if they are grazing freely. The Almsgiving tax laws do not cover trade but other commercial taxes have been imposed during Muslim history.


The fourth pillar is fasting. Fasting is done during the month of Ramadan, which is the th month of the 1-month Islamic lunar calendar. The month of Ramadan is considered to be sacred because the first revelation of the Qu'ran is said to have been done during this month. Ramadan is begun with the sighting of the new moon by at least two Muslims. Fasting must be done the entire month from daybreak to sunset by refraining from eating, drinking and sexual intercourse. The fasting introduces physical and spiritual discipline, reminds rich people the misfortunes of the poor people, and brings all of the Muslims from all different kinds of backgrounds together. Some Muslims choose to eat before daybreak in order to sustain themselves until sunset. After Ramadan is over comes the holiday of breaking the fast and lasts for three days. Fasting during anytime of the year could also be required to make up for offenses and violations of the law that were committed.


The fifth pillar is the performance of pilgrimage to Mecca at least once in their life. Pilgrimage was performed by the Arabs before the rise of Islam and still continues. The ritual of pilgrimage takes place during the 1th lunar month of the year and consists of a set and detailed sequence of rituals that is practiced over several days. All pilgrimage rituals take place in the city of Mecca and the primary focus is a cubical structure called the Kaaba. The Kaaba was said to have been built on God's order by Ibrahim and his son Ismail. Once people arrive in Mecca then the ritual begins. A lot of the men shave their heads and most of the men and women wear white sheets. This simple and common type of dress symbolizes that all Muslims are equal before God. After the ritual purification, everyone circles the Kaaba seven times, runs between al-Safa and al-Marwa seven times and performs several prayers. This part of the ritual is a reenactment of the search by Hagar for water to give to her son Ismail. Once the opening rituals are done, then hajj starts on the seventh day and continues for the next three days. People assemble at Mina, a hill outside of Mecca, where they spend the night. Then the next morning they go to the plain of Arafat, where they stand from noon to sunset and perform a series of prayers and rituals. They then head to Musdalifa to spend the night and head back to Mina the next morning stopping along the way to collect pebbles that symbolizes Satan, at which they throw seven pebbles. The final ritual is slaughtering an animal. The final ritual is a symbol of when God asked Ibrahim to sacrifice his son Ismail, which Ibrahim and Ismail accepted the order from God and were about to do the execution when God allowed Ibrahim to slaughter a ram instead. Most of the meat from the slaughtered animal is then given to the poor Muslims. The ritual sacrifice ends the hajj and starts the festival of sacrifice. The festival of breaking fast and the slaughtering of an animal are the two major Islamic festivals that are celebrated by Muslims worldwide. During the pilgrimage ritual many of the Muslims visit Medina, where the tomb of the Prophet is located, before returning to their homes.


Of all of the Muslim institutions the mosque is the most important place for public expression of Islamic religion and communal identity. The mosque is a physical manifestation of the public presence of Muslims and serves as a point for Islamic social and intellectual activities. Mosques are mentioned in the Qu'ran and the earliest model of a mosque was a residence that Muhammad built when he moved to Medina. The mosque is a designated place for the purpose of prayer. Muslim cities have numerous mosques but there are only a few mosques where the Muslims must meet on Fridays for group prayer. The most important characteristic of a mosque is that is has one or more niches on one of the walls that often serve as indicators of that direction. When an iman leads the group prayers on Fridays he will usually face one of the niches on the wall. Many mosques also have separate areas for performing rituals and separate sections for women. Some mosques also have several rows of columns so that the worshippers can line up behind the imam during prayer. Mosques usually have one or more towers from which the Muslims are called to prayer five times a day. Many of the mosques also have a dome with a line connecting the center of the dome to the niche supposedly pointing to Mecca. However, mosques are always built as a connection with Mecca.


Before Islam, a lot of Arabs believed in the all-powerful, all-knowing God was responsible for creation but they also believed in lesser gods. When Islam came about, Arab's concept of God was done away with the elements of polythesim and turned into a different concept of believing in one God, or monothesim. Status of Arabs before Islam is considered to be an ignorance of God and there are Islamic resources that say Islam brought a complete break from Arab concepts of God and a transformation in Arab belief in God.


Doctrines of Islam say that Islam's monothesim continues that of Judaism and Christianity. However, the Qu'ran and Islamic traditions state that there are differences between Islam and later forms of two other monothesim religions. According to Islam belief, both Moses and Jesus, were prophets sent by God to preach the message of Islam. Moses and Jesus created two legal codes, the Ten Commandants and the Christian Gospels, that are different from that of the Qur'an but according to Islam's understanding all of these codes teach the same thing. People in the scriptures are called either people of the book or the scriptured people. Muslims became scriptured when God revealed his word to them through a prophet "God revealed the Qur'an to the prophet Muhammad, commanding him to preach it to his people and later to all humanity."


Even though the Muslims believed that God gave the original messages of Judaism and Christianity, they also believe that both the Jews and Christians distorted the messages. So the mission of Islam has been to restore what Muslims believe is the original monotheistic teaching and to supplement the older legal codes of the Hebrew and Christian traditions with a newer code of Islamic law that is related to the evolving conditions of human societies. An example of this would be that Islam believed that Jesus was a prophet who revealed the book the Christian New Testament and that later on Christians distorted the original scripture and inserted that Jesus was the Son of God. But according to the Muslim belief, God sent Muhammad with the last and perfect legal code on the spiritual teachings of the law. Also according to the teachings of Islam the Islamic code is the final code, a code that will address humanitarian needs in the most developed stages forever. So for the Muslims, Islamic history is unfolds a divine scheme from the beginning of creation to the end of time. Creation in itself is the realization of God's will in history. The Muslims belief that humans were created to worship God and those prophets came along in order to guarantee that the world was never without knowledge and the proper worship of God. Islam sees the sending of the prophets as an act of mercy from God, that God will never abandon his creations and always provides people with the guidance they need for their salvation in this world and the world to come after. They also believe that God is just and that this justice requires informing people of how to act and what to believe before he, God, holds them accountable on judgment day. God will also punish those who do wrong or do not believe in him and reward them that do right and do believe in him. Muslims believe that God's greatest attribute is that of mercy.


As God did with his other prophets and messengers, he supported Muhammad by allowing him to work miracles and to prove that he was a true prophet. Muhammad's singular miracle and ultimate proof of the truthfulness of Islam is the Qur'an. According to the words of the scripture, Muslims believe that the Qur'an is the ultimate word of God, the like that no other human can produce. The trait for this scripture, called inimitability, is based on the belief of the divine authorship of the Qur'an. Islam, unlike any of the other religious miracles, is a miracle of literary. The belief in the unique nature of the Qur'an had led the Muslims to devote all their intellectual energies to the study of the contents and form of the Qur'an.


The Qur'an is made up of 114 chapters, which are called suras, which are roughly organized from the second chapter on, in order of length, beginning with the longest chapters and ending with the shortest chapters. The first chapter is a short opening chapter that is recited during the five daily prayers. All of the chapters with the exception of one begin with the saying "in the name of God, the Merciful Lord of Mercy." Each of the chapters is also divided into verses, which are randomly organized without a narrative thread. The chapters in the Qur'an may address any of the following topics God and creation, prophets and messengers from Adam to Jesus, Muhammad as preacher and ruler, Islam as a faith and code of life, disbelief and society and law.


Islam still recognizes the divine origins of the earlier Hebrew and Christian Scriptures that represents a restoration and continuation of traditions. Because of this, the Qur'an draws on biblical stories and even repeats many of the themes that are in the Bible. The stories of several biblical prophets appear in the Qur'an, some of theses stories are a condensed version while other stories about certain prophets such as, Abraham and Moses, are given in more detail and even have subtle revisions of the biblical accounts. For example, would be a story related to Jesus, who according to the Qur'an is a mortal, human prophet. But the Islamic faith rejects the idea that God was ever born, as opposed to Christian belief that Jesus was born the Son of God. Islam faith also rejects the idea that God shared his divinity with any other being.


About two decades or so after the Prophet, Muhammad died various copies of parts of the Qur'an existed. These copies were collected by a close group of individuals of Muhammad. This group was commissioned by the third successor of Muhammad, Affan, and this groups effort is the basis of the official text that is currently used by Muslims.


Despite Muslims questioning the authenticity of the Qur'an they all agree to the fact that certain words out of the Qur'an could be interpreted in a number of ways. The Arabic language has constant and vowels and so the meanings of worth come from both. For a long time the Qur'an showed only constants and didn't indicate any vowel marks. As a result of this, some of the words can be said in different ways and have different meanings. One of the individuals that are studying the documentation of acceptable and unacceptable readings has found that there are about 40 possible readings of the Qur'an and 7 to 14 of these readings are valid. The meaning of some of the Qur'an verses are not always clear because some of the verses are described as either unambiguously clear or ambiguously clear because it's meaning is only known to God. The Qur'an is considered to be the primary source of authority on law and theology and identity in Islam. However, in a lot of cases the Qur'an is either totally silent about important Islamic beliefs or gives only general guidelines.


The hadith is considered to be the second source of authority in Islam and complements the Qur'an. It provides the most extensive source for the Islamic law. The understanding of the Qur'an depends upon the context of Muhammad's life and the ways in which he demonstrated and applied the message. However, the hadith was circulated orally and there were no attempts to establish it until about the beginning of the second century of Islam. Muslim scholars implemented a group of people to examine and verify the authenticity of reports attributed to the Prophet in order to be able to establish the authority for the hadith. Contents of sayings and reliability of those who transmitted them were carefully looked at and then the hadith was divided into groups ranging from the sound and reliable to ones that was lies and rejected. This effort concluded in compiling several collections of the hadith that were known to be authentic. There were 6 compilations of the hadith altogether and two of these were considered by the Muslims to be the most important sources for Islamic authority after the Qur'an. These are Sahih Muslim and Sahin Bukhari. There is no doubt that both the Qur'an and the hadith were used to derive laws that would govern the lives of the Muslims. By the th century both the Qur'an and hadith were used constantly and also introduced the legal authority for Islam. This legal theory states that there are four sources from which Islamic law comes from. These four sources, in order of priority, are the Qur'an, the hadith, consensus of the community and legal analogy.


Since Islam was introduced the Muslims have perceived it to be a universal code. During the time of Muhammad, two attempts had been made to expand northward into the Byzantine domain and the capital in Constantinople and then ten years after the death of Muhammad; the Muslims had defeated the Sassanids of Persia and the Byzantines. The Muslims also defeated most of Persia, Iraq, Syria and Egypt. These battles continued and the Sassanian Empire was destroyed and the influence of Byzantium was diminished.


Muhammad had four successors, these successors were known as rightly guided caliphs and ruled for about 0 years. Their rule is considered by Muslims to constitute the ideal Islamic age. Umar, who was the second caliph, ruled from 64-644. He was the first caliph to found new Islamic cities, Al Basra and Kufah. From these two cities the administration of the eastern and western provinces were coordinated. Uthman, the third caliph, was murdered by a group of Muslims. The fourth caliph was Ali, he succeeded to power and move his capital to Kufah located in Iraq. Ali fought many different opposing factors from the capital. Ali had followers who were known as Shia of Ali. This group of followers originally started out as a political group but ended up becoming a sect with specific theological and doctrinal positions. A key event in the history of the Shia was the death of Ali's son, Karbala of Husayn and Muhammad's daughter Fatima. Husayn refused to recognize the rule of the Umayyad Yazid and so Husayn went to Kufah to rally support for his cause. But his plans were exposed before he even reached Kufah and a large army of the Umayyad met Husayn and 70 members of his family. Umayyad offered Husayn the choice of being humiliated by submitting to his rule or a battle, which would end in death for he and his family. Husayn chooses to do battle and so he and all of his family members were killed. The battle really didn't have much impact from a military point of view but it definitely redefined the history of Shia Islam. Even not all of the Muslims are Shia Muslims; all of the Muslims still view Husayn as a martyr for living up to his principles and dying for them.


During the early period of Abbasid, Sunni Islam was defined and included followers from four of the legal schools. The four legal schools were the Malikis, Hanafis, Shafi'is and Hanbalis. The Sunnis believed that leadership was in the hands of the Muslim community. Consensus of historical communities, not on the decisions of the political authorities, is what led to the establishment of the four legal schools. So a Muslim could choose whichever school of Islamic thought that they wished to pursue and could change their mind at anytime. These religious scholars enjoyed respect and popularity which ended up making them effective in the area of social power which the ran across the political authorities.


After the first four caliphs, the religious and political authorities in Islam were never again united under one institution. Their coexistence was underscored by the mutual recognition that they had separate areas of influence, duties and responsibilities. However, there were times the two powers did collide.


The Islamic culture had started to evolve under the rule of the Umayyads and grew to maturity during the first century of the Abbasid dynasty. The Abbasids came to power when the armies from Khorasan defeated the armies of Umayyads. This caused the Islamic capital to move to Iraq under Abbasidian rule. The Abbasid rulers chose a site on the Tigris River to rule. The site ended up becoming the City of Peace, Baghdad. Baghdad remained to be the political and cultural capital of the Islamic world until the Mongol invasion that took place in 158. Hulagu, one of the grandson's of the Mongol ruler Genghis Khan, led his armies across the Zagros Mountains of Iran and destroyed Baghdad murdering about one million Muslims. Then in about 160, Hulagu and his army marched into Syria where the Mamluks of Egypt finally defeated them. So for the next two centuries or so, Islamic power switched between Egypt, Syria and some local dynasties.

Question B Rise of Christianity and Decline of the Roman Empire


So many people have lost their faith in their government and so they tried to put their faith into religion. Because of this a lot of people became interested in the Christian faith. The Romans converted to the Christian faith because it made sense to them because of the strict moral code and descriptions of society being evil. Christianity offered a positive attitude in regards to humanity, a belief in the sacredness of human life and mutual love. A benefit to believing in the Christian faith was that the Christian's God had a face, which made it a lot easier to worship than to worship a god that had no face and could not be seen. Jesus was considered to be a common man with a message and the Romans could see their suffering through his suffering. Jesus promised the Christians a world without suffering which appealed to the Roman's along with the words of Jesus such as deeds, love for all and belief in justice. The other benefits of Christianity was it was more structured and united and also from being exposed to other people who were either barred or overlooked by other religions such as women, non-citizens and yes even slaves. The Christian faith pleased the slaves because they would still be slaves in real life but in God's eyes a good person was never considered to be a slave. It appealed to even poor people because it was said that poverty was one of the advantages of salvation after you died. You could convert to Christianity with ease because all you had to do was be baptized. So this allowed everyone to join the Christian faith and so it also appealed to the upper-class people. More upper-class women than men had converted to Christianity and this caused the women to look for husbands among the poor and the slaves. However these marriages were actually illegal according to the Roman law, but the bishop of Rome still allowed them. When an individual became a Christian, they really joined a community that looked our for the welfare of one another, shared their meals and wealth, and took care of the needy among them. The persecution of the Christians was not frequent in Rome until about the mid-00s. The persecutions of Christianity only began after a national disaster such as an earthquake because the Roman's blamed the Christians for the anger of the gods. Another reason for persecution of Christianity was because the more the faith grew the more Christians became visible and the Romans feared that Christians would be the reason for the end of the world. So Rome ended up saying Christianity was illegal, and went as far as to hold Christians accountable for crimes that they didn't even commit. Philippus, an Arabian emperor, had sympathy for a Christian writer by the name of Origen who was pleading for justice. Philippus was also a military leader that had plotted against his previous leader and then in turn a General named Gaius Decius replaced Philippus in 4. After Decius moved his military from Pannonia to Italy, he became the eighth emperor of Rome. He wanted to restore order and save the empire from economic ruin, so he ordered the Romans to perform roman rituals to the gods in order to put the empire in a good position in God's eyes and to also make his authority as emperor even greater. Jews were excused from these Roman rituals but not Christians. As the Christians protested more and more about having to do the rituals they ended up drawing more attention on themselves. Decius hoped for Christian conversion in order to please the gods and for the well being of Rome. He ordered people that were suspected being Christian to perform the Roman rituals and to make sacrifices to prove that they were loyal to the Gods of Rome. The Christians that did participate in the rituals and sacrifices were given papers to carry around with them so that they wouldn't be persecuted. Some people who wanted to escape persecution would do the rituals, some would do bribery and others would go into hiding. Still a lot of Christians such as bishops of Rome were arrested by the Roman government and executed. The executions still brought more and more attention to the Christians. Many people were impressed by how the Christians were willing to die and suffer for what they believed in and saw the state as the enemy. People of Rome also preferred Christians to soldiers and so as the persecutions grew so did Christianity. Gaius Gallus, a military commander to Decius, took over and to prove that God was angrier with Decius than the Christians he led Decius, his family and military into a swamp and had them killed. Gallus did away with the laws on Christianity. So after the threat of persecution of Christians had disappeared, many people who were Christian before wished to re-enter the church but this stirred up a lot of controversy because even though the baptism cleansed someone of all sins, if it were to become dirtied again then it would stay that way until that person died. This fight led to debate as to whether the church was a gathering of sinners trying to gain redemption. In 51, the church decided to allow individuals to re-enter the church on the condition that they no longer worshipped the gods of Rome. By the 00s, half of Rome and largely all of North Africa had converted to the Christian faith. Two kings had also converted to Christianity, the king of Osroene in the northeastern part of Mesopotamia and the king of Armenia. Now the Christians were holding jobs as civil servants in the local government, and they were serving in Tome's militaries. Soon after the Christians were making the sign of the cross in order to ward off the demonic influences of a ritual being performed by the Diocletians, Diocletian ordered everyone in the place to worship the gods or be beaten. Then Galerius palace was burned and the blame was put on the Christians and so once again the Christians were ordered to worship the gods or face the death penalty. Christian meetings were banned, bibles were taken away and burned and the churches were ruined. But by this time Christians had become to numerous to be demolished because the Roman Empire had failed to develop a way to kill a bunch of people all at once. Furthermore, since Christians could read and write they had become a vital importance to the government. In the year 05, Diocletian retired due to bad health. Galerius, vice-emperor in the east, started sharing the rule of the empire with the vice-emperor in Rome and the west Constantius. Then the next year Constantitius was in Britain commanding his military against raids in Rome by the Scots and he got killed. So his military selected his son Constantine, to follow him. Constantine served briefly in the military under Diocletian in Egypt and under Galerius. He would modify the world by becoming the first Christian emperor. I think that Christianity still thrives in our lives today, but it brought the downfall of a great nation. Our beliefs are the same but there are more modified versions of Christianity today such as being catholic or Methodist. Even though we can choose any religion we want, without the threat the persecution, unlike the Christians that lived in Rome, but no religion can ever escape from prejudice, so although it has changed, it is still the same.


Rise of Christianity in the Roman Empire


The rise of Christianity led to a lot of new ideas about the nature of God. The Christians went off the religion of the Jews, which was the belief in one God who was more powerful than all of the Roman gods put together. The new God was also loving and caring, of turning the other cheek and to love everyone one unconditionally. This new God also needed to be defended against all critics and also placed on a pedestal for the rest of the world to see the supreme power that he held. There were Medieval philosophers who dealt with the question whether or not God existed.


Aquinas believed that were five different ways in which he prove the existence of God. The proofs were motion, the nature of efficient cause, possibility and necessity, the gradations found in things and design.


The first theory is related to Aristotle's argument of the unmoved mover, which is "(t)here are things which are moved, and other things which both move and are moved. Whatever is moved is moved by something, and, since an endless regress is impossible, we must arrive somewhere at something which moves other things without being moved. This unmoved mover is God." So God is at the top of causes, and has caused the causes. So the first proof of motion is that something does not move on it's own, that it must be moved by something else.


The second proof, efficient cause, is much the same as the first proof. The difference between efficient cause and motion is the cause and effect relationship. In the case of the first proof, once could say that a rolling stone is only rolling because something pushed it. With the theory of the second proof, one would continue by saying that the squirrel would not have died if the rolling stone had not crushed it. Therefore, the rolling stone was the cause and the crushed squirrel was the effect.


The third proof is to the existence of God comes from the possibility and the necessary. Aquina says on this theory that "we find in things some which are able to be and some which are able to be and not be, since some things are found to be generated and corrupted, and consequently able to be and not to be. But it is impossible that all things which are like this always exist; because what is not able to be, at one time does not exist." He continues on to say that this cannot be because it leads to the conclusion that "even now there would be nothing, since that which is not does not begin to be except through something which is." He claims this is impossible, and that as a result there must be something, which is necessary, without the cause of its necessity being external and which is the cause of other things. He claims this is God.


The fourth proof was that there must be something, which is to all beings the cause of their being, goodness, and every other perfection; and this is what we call God. This is the theory is the gradation to be found in things and the main argument with this theory is that "as fire, which is the maximum heat, is the cause of all hot things, then there must be something which is the cause of all goodness in humanity which deserves the name of God."


Aquinas' fifth proof, which is the belief that every living thing in the world has an ultimate purpose and that God guided and manipulated events in order for these goals, could be met.


Aquinas also believed that God was infinitely good and found it very easy to work out of the skepticism of "If God is supremely good, and directs all things toward their end, then why is there evil?" So he used St. Augustine's argument from the Enchiridion that God is so powerful that he can work well from that which is evil. He went even further to say that God is showing his goodness by allowing evil to even exist and then turns it into goodness.


The victory for the Christian faith as the official and only tolerated religion for the Empire went along with the beginning of the invasion of the Germans into Western Europe. Many of the Germans had already converted over to the Christian faith before the invasion took place but the conversion did not effect any marked transformation of the Germans cultural values.


So really it is not surprising that the Germans failed to grasp the full Christian message. Clovis, the first Christian king of the Franks, became Christian and meant to the protection and support of a god that was more powerful than the one that he was already worshipping. He was doing this for his own personal designs. Gregory, bishop of Tours, the historian of Clovis' reign, commended everything that Clovis had done because he had espoused the Roman doctrine in preference to the Arian heresy that was accepted by many of the German invaders. I don't either one of them thought to try and practice the Christian faith.


Of course, the Christian faith had changed since the time of its founders. When a religion begins to take it shape it does so from a set of factors such as; the teachings of its founders, interpretation of those teaching by successors, the organization set up for worship and religious discipline, mental attitudes and traditions of those that convert, and conditions under which the religion spreads.


To begin the development of Christianity you have to ascertain the Jesus was a Jew. His way of teaching life and faith systematically came from the long tradition of Judaism. He emphasized the love and mercy of God, how unimportant that wealth and worldly power really was and the promise of redemption in the hereafter.


Jesus did not withdraw from society but went out to teach among the poor and to help and heal the sick. His intentions were to change the conditions of the world and to give people hope for the hereafter. He also taught the observance of ancient Jewish law but also stated that the law was meant for man and not man for the law. Most of the Jews did not accept Jesus as the Messiah that would bring the world justice and righteousness from now and forever. Many people saw him as an imposter and subverter of the social order. Even though little is really seen as imposing a threat to the Romans and Jewish he was still arrested and crucified. From his brief but tragic story of his life, his followers created a powerful and enduring myth that became the core of Christianity as it spread throughout the world.


Peter, one of the 1 disciples that Jesus had chosen, and Paul, converted to Christianity and also who had persecuted Christians, started preaching the faith to the Gentiles and Jews and the only observance that was required were the basic teachings of the ancient Hebrews. The decision to continue the preaching caused the religion to spread throughout the Roman Empire and even beyond its boundaries and was the first experiment in mass education that the world had ever seen.

Question A Rise and Early Development of Islam


Islam is one of the three major religions in the world that professes the belief in a single God. In Arabic language, the word Islam means surrender or submission to the will of Gods. A follower of Islam is called a Muslim meaning to surrender to God. The Arabic word for God is Allah refers to the same God that is worshipped by the Jews and Christians. Islam's teaching of God is that there is only one all-powerful, all-knowing God and that this God created the universe. This rigorous type of belief in a single God as well as Islamic teachings that all Muslims are equal before God provides for a sense of loyalty to God that goes beyond class, race, nationality and even differences in religious practices. So all Muslims belong to one community regardless of their ethnic or national background.


After the rise of Islam in the 7th century, it spread its origins into Syria, Egypt, North Africa, and Spain to the west, and into Persia, India, and by the end of the 10th century also to the east. In the following centuries, Islam also spread into Anatolia and the Balkans to the north and Africa to the south. There are about one million Muslim followers on all five continents and is considered to be the fastest growing religion in the world.


One of the reasons that the Muslim community has grown is because of its openness to new members. Children that are born to Muslim parents are automatically considered to be Muslim. A Muslim can convert to Islam at anytime by declaring they to be a Muslim. A person's declaration that they are Muslim is evidence enough of the conversion and doesn't need to be confirmed by anyone else or even by the religious authorities.


Muhammad, the founding prophet of Islam, was born in Mecca around ad 570. His uncle, who had religious contacts within the main Quraysh tribe of Mecca, raised him. He got married at the age of 5 to a wealthily woman of 40, Khadija. At the age of 40, Muhammad had his first experience of Islam after retreating to hills outside of Mecca. The angel, Gabriel had come to Muhammad in a dream. Gabriel told Muhammad that God had chosen him to be a messenger for him and also told him of the first revelation of God. After awaking from the dream, Muhammad was terrified and shaken and so returned home. His wife was the first person to hear his message and she converted to Islam. He received several more additional revelations, which caused him to start preaching the new religion. At first the Meccans ignored Muhammad's message and made fun of him. When more and more people started accepting Muhammad's message, the Meccans only became more aggressive. At first the Meccans tried to persuade Muhammad away from this new religion and when that failed they started persecuting his followers and when that still didn't work the Meccans persecuted Muhammad. During this time, a couple of tribes from the city of Yathrib invited Muhammad to live there. The leaders of the tribe invited Muhammad to settle disputes as an impartial religious authority and in return for Muhammad doing this the leaders promised to accept Muhammad as a prophet and support his new religion. This new religion taught that there was one God and Muhammad was considered to be the last of the prophets and messengers. God had sent various codes through his messengers, or systems of laws to live by, culminating in the Qur'an, which is the holy book of Islam. The messengers were mortal men and included men such as Moses. Muhammad is portrayed in the Qur'an as a person who makes mistakes but does not sin against God. God corrected Muhammad's mistakes and errors and judgments, so that his life could serve as an example for other Muslims to follow. The emphasis that is put on Muhammad's humanity serves as a reminder that other humans can also strive to lead a good life.


Islam taught that the Christian Bible along with the Qur'an were holy books. There were two earlier scriptures that had been altered over time from their original forms given by God but the Qur'an would remain perfect, preserved by God from being altered. This new law also taught that the God of Islam had provided humanity with a means to be able to tell good from evil. So on the Day of Judgment people would be held accountable for their actions.


But the teachings of Muhammad drew a lot of hostility and severe opposition. He ended up leaving Mecca and sought refuge in the city of Yathrib. The name of the city Yathrib was changed to Medina (meaning the city) upon Muhammad's arrival. The date of his immigration was later set as the beginning of the 1-month lunar Islamic calendar.


During the ten years that Muhammad spent in Islam before arriving in Medina he had laid the foundation for the ideal Islamic state. A group of committed Muslims was established and a community life was ordered per the requirements of the new religion. From this came about the five pillars of Islam which is the essential religious duties that is required of every capable adult Muslim. Some of the five pillars are described in the book Qur'an and were already being practiced during the lifetime of Muhammad. The five pillars are the profession of faith (shahada), prayer (salat), almsgiving (zakat), fasting (sawm) and pilgrimage (hajj). The five pillars are the most central rituals of Islam and constitute the practices of the Islamic faith. Some Muslims also believe that there is a sixth pillar, which is Jihad and has been understood as holy war. But the word Jihad in Arabic means to struggle in order to please God. According to Islam faith this effort can either be collective or individual and can also apply to leading a good life such as; helping out other Muslims whether through charity, education or by other means.


The first of the five pillars is the profession of the Muslim faith. The focus of Islamic piety is Allah, the all-powering, all knowing and above all, the all-merciful God. Allah is believed to have brought the world to its being and will sustain it until its end. If they obey the commands of God then they are expressing their recognition of and gratitude for the wisdom of creation and to live in harmony with the world. The profession of the Muslim of faith is all it takes to become Muslim. Several times a day and when they say their daily prayers the profession of the Muslim faith are repeated constantly. The words that are said to profess the faith of Muslim are as follows "I bear witness that there is no god but Allah and the Muhammad is his prophet." These words can be said anywhere at anytime. When an individual professes the Muslim faith then this is considered to be enough evidence to be a Muslim and cannot be challenged by any other Muslims.


The second pillar is the religious duty to say five daily prayers. All adult Muslims are required to say five daily prayers, followed by a ritual cleansing of the body at different times during the day. Muslims used to have to face Jerusalem during these prayers but this changed during Muhammad's time and then they had to face the Kaaba, an ancient shrine in the city of Mecca.


There are really no set descriptions for the five prayers only that the example was set by Muhammad which are later preserved in Islamic traditions. The five daily prayers are required to be performed at certain times of the day dawn, noon, midafternoon, sunset and evening. The prayers that are said at dawn, noon and sunset prayers do not begin at these precise times but a short time after.


The prayer is made up of a sequence of units that are called bowings. During each of these bowings, the person praying has to stand, bow, kneel and prostrate while reciting verses from the Qur'an along with other types of prayer. These prayers are repeated four times each time the person has to pray at the set times during the day except the prayer is only repeated three times during sunset and twice at dawn. A group prayer is required at noon on Fridays. The Friday group prayer is led by a prayer leader and differs from the other prayers that are said at noon during the week. The prayer is always concluded with the profession of the Muslim faith followed by the greeting "may the peace, mercy, and blessings of God be upon you." The purpose of the daily prayer is communication with God in order to maintain the presence of God in their daily lives. It also provides discipline that structures the day and fosters a sense of community and shared identity among the Muslim people.


The third pillar is Almsgiving. This is a religious obligation and expresses a devotion to God. It tries to provide for the poorer sections of the community and offers a means for Muslim people to purify their wealth to attain salvation. Islamic traditions along with the Qu'ran strongly encourages charity and reminds the Muslim's of their moral obligation to the poor, orphans and widows. The Qu'ran does however distinguish between general, voluntarily giving and the obligation to give money or produce. It identifies specific ways that this tax is allowed to be spent which includes spending the money on the poor and needy, on those who collect and distribute the Almsgiving, those who the Muslims are trying to convert over to Muslim, travelers, and on the cause of God. The Qu'ran doesn't go into detail about what kinds of things are subject to the Almsgiving tax or even the precise share of income or property that should be paid. An example is, one-fortieth of assets that are accumulated during the year (to include gold and silver as well as money) is payable at the end of the year or one-tenth of the harvest of the land is payable at harvesting time. If the Muslims have animals such as cattle or camels would be subject to a more complex tax depending on the animal such as age of the animal, number of animals, and if they are grazing freely. The Almsgiving tax laws do not cover trade but other commercial taxes have been imposed during Muslim history.


The fourth pillar is fasting. Fasting is done during the month of Ramadan, which is the th month of the 1-month Islamic lunar calendar. The month of Ramadan is considered to be sacred because the first revelation of the Qu'ran is said to have been done during this month. Ramadan is begun with the sighting of the new moon by at least two Muslims. Fasting must be done the entire month from daybreak to sunset by refraining from eating, drinking and sexual intercourse. The fasting introduces physical and spiritual discipline, reminds rich people the misfortunes of the poor people, and brings all of the Muslims from all different kinds of backgrounds together. Some Muslims choose to eat before daybreak in order to sustain themselves until sunset. After Ramadan is over comes the holiday of breaking the fast and lasts for three days. Fasting during anytime of the year could also be required to make up for offenses and violations of the law that were committed.


The fifth pillar is the performance of pilgrimage to Mecca at least once in their life. Pilgrimage was performed by the Arabs before the rise of Islam and still continues. The ritual of pilgrimage takes place during the 1th lunar month of the year and consists of a set and detailed sequence of rituals that is practiced over several days. All pilgrimage rituals take place in the city of Mecca and the primary focus is a cubical structure called the Kaaba. The Kaaba was said to have been built on God's order by Ibrahim and his son Ismail. Once people arrive in Mecca then the ritual begins. A lot of the men shave their heads and most of the men and women wear white sheets. This simple and common type of dress symbolizes that all Muslims are equal before God. After the ritual purification, everyone circles the Kaaba seven times, runs between al-Safa and al-Marwa seven times and performs several prayers. This part of the ritual is a reenactment of the search by Hagar for water to give to her son Ismail. Once the opening rituals are done, then hajj starts on the seventh day and continues for the next three days. People assemble at Mina, a hill outside of Mecca, where they spend the night. Then the next morning they go to the plain of Arafat, where they stand from noon to sunset and perform a series of prayers and rituals. They then head to Musdalifa to spend the night and head back to Mina the next morning stopping along the way to collect pebbles that symbolizes Satan, at which they throw seven pebbles. The final ritual is slaughtering an animal. The final ritual is a symbol of when God asked Ibrahim to sacrifice his son Ismail, which Ibrahim and Ismail accepted the order from God and were about to do the execution when God allowed Ibrahim to slaughter a ram instead. Most of the meat from the slaughtered animal is then given to the poor Muslims. The ritual sacrifice ends the hajj and starts the festival of sacrifice. The festival of breaking fast and the slaughtering of an animal are the two major Islamic festivals that are celebrated by Muslims worldwide. During the pilgrimage ritual many of the Muslims visit Medina, where the tomb of the Prophet is located, before returning to their homes.


Of all of the Muslim institutions the mosque is the most important place for public expression of Islamic religion and communal identity. The mosque is a physical manifestation of the public presence of Muslims and serves as a point for Islamic social and intellectual activities. Mosques are mentioned in the Qu'ran and the earliest model of a mosque was a residence that Muhammad built when he moved to Medina. The mosque is a designated place for the purpose of prayer. Muslim cities have numerous mosques but there are only a few mosques where the Muslims must meet on Fridays for group prayer. The most important characteristic of a mosque is that is has one or more niches on one of the walls that often serve as indicators of that direction. When an iman leads the group prayers on Fridays he will usually face one of the niches on the wall. Many mosques also have separate areas for performing rituals and separate sections for women. Some mosques also have several rows of columns so that the worshippers can line up behind the imam during prayer. Mosques usually have one or more towers from which the Muslims are called to prayer five times a day. Many of the mosques also have a dome with a line connecting the center of the dome to the niche supposedly pointing to Mecca. However, mosques are always built as a connection with Mecca.


Before Islam, a lot of Arabs believed in the all-powerful, all-knowing God was responsible for creation but they also believed in lesser gods. When Islam came about, Arab's concept of God was done away with the elements of polythesim and turned into a different concept of believing in one God, or monothesim. Status of Arabs before Islam is considered to be an ignorance of God and there are Islamic resources that say Islam brought a complete break from Arab concepts of God and a transformation in Arab belief in God.


Doctrines of Islam say that Islam's monothesim continues that of Judaism and Christianity. However, the Qu'ran and Islamic traditions state that there are differences between Islam and later forms of two other monothesim religions. According to Islam belief, both Moses and Jesus, were prophets sent by God to preach the message of Islam. Moses and Jesus created two legal codes, the Ten Commandants and the Christian Gospels, that are different from that of the Qur'an but according to Islam's understanding all of these codes teach the same thing. People in the scriptures are called either people of the book or the scriptured people. Muslims became scriptured when God revealed his word to them through a prophet "God revealed the Qur'an to the prophet Muhammad, commanding him to preach it to his people and later to all humanity."


Even though the Muslims believed that God gave the original messages of Judaism and Christianity, they also believe that both the Jews and Christians distorted the messages. So the mission of Islam has been to restore what Muslims believe is the original monotheistic teaching and to supplement the older legal codes of the Hebrew and Christian traditions with a newer code of Islamic law that is related to the evolving conditions of human societies. An example of this would be that Islam believed that Jesus was a prophet who revealed the book the Christian New Testament and that later on Christians distorted the original scripture and inserted that Jesus was the Son of God. But according to the Muslim belief, God sent Muhammad with the last and perfect legal code on the spiritual teachings of the law. Also according to the teachings of Islam the Islamic code is the final code, a code that will address humanitarian needs in the most developed stages forever. So for the Muslims, Islamic history is unfolds a divine scheme from the beginning of creation to the end of time. Creation in itself is the realization of God's will in history. The Muslims belief that humans were created to worship God and those prophets came along in order to guarantee that the world was never without knowledge and the proper worship of God. Islam sees the sending of the prophets as an act of mercy from God, that God will never abandon his creations and always provides people with the guidance they need for their salvation in this world and the world to come after. They also believe that God is just and that this justice requires informing people of how to act and what to believe before he, God, holds them accountable on judgment day. God will also punish those who do wrong or do not believe in him and reward them that do right and do believe in him. Muslims believe that God's greatest attribute is that of mercy.


As God did with his other prophets and messengers, he supported Muhammad by allowing him to work miracles and to prove that he was a true prophet. Muhammad's singular miracle and ultimate proof of the truthfulness of Islam is the Qur'an. According to the words of the scripture, Muslims believe that the Qur'an is the ultimate word of God, the like that no other human can produce. The trait for this scripture, called inimitability, is based on the belief of the divine authorship of the Qur'an. Islam, unlike any of the other religious miracles, is a miracle of literary. The belief in the unique nature of the Qur'an had led the Muslims to devote all their intellectual energies to the study of the contents and form of the Qur'an.


The Qur'an is made up of 114 chapters, which are called suras, which are roughly organized from the second chapter on, in order of length, beginning with the longest chapters and ending with the shortest chapters. The first chapter is a short opening chapter that is recited during the five daily prayers. All of the chapters with the exception of one begin with the saying "in the name of God, the Merciful Lord of Mercy." Each of the chapters is also divided into verses, which are randomly organized without a narrative thread. The chapters in the Qur'an may address any of the following topics God and creation, prophets and messengers from Adam to Jesus, Muhammad as preacher and ruler, Islam as a faith and code of life, disbelief and society and law.


Islam still recognizes the divine origins of the earlier Hebrew and Christian Scriptures that represents a restoration and continuation of traditions. Because of this, the Qur'an draws on biblical stories and even repeats many of the themes that are in the Bible. The stories of several biblical prophets appear in the Qur'an, some of theses stories are a condensed version while other stories about certain prophets such as, Abraham and Moses, are given in more detail and even have subtle revisions of the biblical accounts. For example, would be a story related to Jesus, who according to the Qur'an is a mortal, human prophet. But the Islamic faith rejects the idea that God was ever born, as opposed to Christian belief that Jesus was born the Son of God. Islam faith also rejects the idea that God shared his divinity with any other being.


About two decades or so after the Prophet, Muhammad died various copies of parts of the Qur'an existed. These copies were collected by a close group of individuals of Muhammad. This group was commissioned by the third successor of Muhammad, Affan, and this groups effort is the basis of the official text that is currently used by Muslims.


Despite Muslims questioning the authenticity of the Qur'an they all agree to the fact that certain words out of the Qur'an could be interpreted in a number of ways. The Arabic language has constant and vowels and so the meanings of worth come from both. For a long time the Qur'an showed only constants and didn't indicate any vowel marks. As a result of this, some of the words can be said in different ways and have different meanings. One of the individuals that are studying the documentation of acceptable and unacceptable readings has found that there are about 40 possible readings of the Qur'an and 7 to 14 of these readings are valid. The meaning of some of the Qur'an verses are not always clear because some of the verses are described as either unambiguously clear or ambiguously clear because it's meaning is only known to God. The Qur'an is considered to be the primary source of authority on law and theology and identity in Islam. However, in a lot of cases the Qur'an is either totally silent about important Islamic beliefs or gives only general guidelines.


The hadith is considered to be the second source of authority in Islam and complements the Qur'an. It provides the most extensive source for the Islamic law. The understanding of the Qur'an depends upon the context of Muhammad's life and the ways in which he demonstrated and applied the message. However, the hadith was circulated orally and there were no attempts to establish it until about the beginning of the second century of Islam. Muslim scholars implemented a group of people to examine and verify the authenticity of reports attributed to the Prophet in order to be able to establish the authority for the hadith. Contents of sayings and reliability of those who transmitted them were carefully looked at and then the hadith was divided into groups ranging from the sound and reliable to ones that was lies and rejected. This effort concluded in compiling several collections of the hadith that were known to be authentic. There were 6 compilations of the hadith altogether and two of these were considered by the Muslims to be the most important sources for Islamic authority after the Qur'an. These are Sahih Muslim and Sahin Bukhari. There is no doubt that both the Qur'an and the hadith were used to derive laws that would govern the lives Please note that this sample paper on Rise and Early Development of Islam is for your review only.

Brave New World George Santayana once said, "Ideal society is a drama enacted exclusively in the imagination." In life, there is no such thing as a "complete utopia", although that is what many people try to achieve. Aldous Huxley's Brave New World is an attempt at a utopian society. In this brave new world, mothers and fathers and family are non-existent. Besides being non-existent, when words of that sort are mentioned, ears are covered and faces of disgust are made. In a report to the Controller, Bernard wrote,"…This is partly due, no doubt to the fact that he heard them talked about by the woman Linda, his m-----"(106). Words of the sort cannot even be written. Art, history, and the ability to have emotions are shunned. This utopia is shown as a perfect world in which everyone is happy. If this was true, the people would not need to take soma, an equivalent along the lines of a cross between one of today's "designer drugs" and Prozac. The Director, who goes nameless for most of the story, is less important than the controller is, and he also knows less. This is shown by his shock when the Controller dares to speak about two of the forbidden topics, history and biological parents. It is believed that topics of this nature will cause this utopia to deteriorate. Once the utopia deteriorates, people are not happy all the time. Even by its own criteria though, Brave New World is not a society where everyone is in fact happy. There are asylums in Iceland for Alpha misfits. Even in this so-called utopia, no one is perfect. Lenina has lupus and Bernard is emotionally unstable, due to a mistake in the "bottling-plant." If a person is to run out of soma, they feel sick. It may seem to be a utopia, but in essence, brave new world is far from it. Well-being is not and can not be, genetically pre-programmed, but that is what the soma is for. When one of the inhabitants experiences unpleasant thoughts or emotions, which supposedly do not exist anyway, they receive soma "One cubic centimeter cures ten gloomy sentiments( )." Although the people here are allegedly emotionless, it is shown that they are far from it. Bernard is overcome by feelings of non-conformity. He feels that people should be monogamous, he has emotions, he believes in love. Bernard loves Lenina. This is a concept, though, which is too abstract for these inhabitants to fully understand. Bernard realizes that he is not the only one that feels this way when the Director speaks of an occurrence over twenty-five years ago, which is alone, bad manners in this "utopia." The fact that he still dreams of this occurrence shows that he was more emotion than what is "good for you" in this system. When Bernard brings Linda and her son, John to the Director, he responds with disgust. After this, Linda's face twists "grotesquely into the grimace of extreme grief ( )", an emotion that is unknown to these sheltered people. It is impossible to live in a perfect society, because nothing can be forever perfect, and what is perfect for one, the Director for example, may not be perfection to another, like Bernard. In order to overcome the possibility of this happening, all must lead sheltered lives. A life without love and emotion is far from perfect though. To combat the unhappiness, the "perfect" drug, soma is taken. Even soma is not perfect. Taken in excess, soma is lethal, and that is how Linda dies. After her death, her son commits suicide. If all were perfect, suicide would be unheard of. So once again, nothing in this brave new world is actually perfection. There is no such thing as a utopia. A utopia cannot be achieved because nothing that is perfect for one is perfect for all, no matter how sheltered their lives may be. This brave new world may have been the idealistic society for some, but not all, because if it was what everyone wanted, it could not be overturned. This brave new world was, in fact destroyed. Love, feelings, and emotions destroyed it. Nothing can be completely flawless, and that is why not a single utopia exists today

Mysteries are captivating and entertaining stories that make the mind work in a unique and creative way. Plot twists occur throughout, ensuring that the readers' full attention if he or she wants to solve the mystery. Mysteries all contain key elements that are essential in characterizing them as a mystery settings found in these short stories are crucial, as they enable, the reader to picture exactly where the events of the work are taking place. Symbolism or animal imagery is necessary in mystery short stories, as it adds to the description of the happenings in the plot.

The Best American Mystery Stories of the Century are defined as mystery stories because they posses the key elements of a mystery, setting, symbolism and animal imagery, and characterization.


The setting is indispensable in the creating of a mystery story because it gives a clear description of the environment of the story. The setting allows the reader to feel involved in the story and think of what it must be like to be present in the place where the events partake. In Paul's Case by Willa Carter, a vivid description of Paul's house was given which made visualizing this setting relatively easy.


"The nearer he approached the house, the more absolutely unequal Paul felt to the sight of it all; his ugly sleeping chamber; the cold bathroom with the grimy zinc tub, the cracked mirror, the dripping spigots." (Hillerman 1)


In An Error in Chemistry by William Faulkner, a well writing description of Joel Flint's old workplace is given.

"A lighted booth where a roulette wheel spun against a bank of nickel-plated pistols and razors and watches and harmonicas, in a traveling carnival." (Hillerman 1)


In The Murder by John Steinback, grand description of the scenery of the Canon del Castillo was given.


"From the main Canon del Castillo a number of little arroyos cut back into the mountains, oak-wooded canyons, heavily brushed with poison oak and sage. At the head of the canyon there stands a tremendous stone castle, buttressed and towered.' (Hillerman 1)


A well done setting is a very important asset to a short story, especially when symbolism and animal imagery is used when describing certain parts of the setting.


Symbolism and animal imagery make understanding the events easier, as they give a new and unique description of the proceedings of the plot, which makes visualizations of the story effortless. It helps the reader to picture something that is easier to imagine, which in turn makes visualizing the story relatively simple. The Comforts of Home by Flannery O'Connor uses a simile to allow us to understand how loud the telephone seemed to ring.


"Two nights later, his mother and he were sitting in the den after their supper, each reading a section of the evening paper, when the telephone began to ring with the brassy intensity of a fire alarm." (Hillerman 48)


In Paul's Case, Paul wears a red carnation on his shirt when he goes to meet with his teachers, which is a sign of his outlandish attiude.


"His teachers felt this afternoon that his whole attitude was symbolized by his shrug and his flippantly red carnation flower, and they fell upon him without mercy." (Hillerman )


In The Murder, animal imagery is used when describing Jelka, Jim, the protagonist's wife.


"Jelka had eyes as large and questioning as a doe's eyes. Her nose was thin and sharply faceted and her lips were deep and soft." (Hillerman 14)


Symbolism is a key element found within all short stories, and they are extremely important when developing the characters of the story.


Characterization is essential to ensure the reader can picture and understand both the appearances and attitudes of the protagonist of the story. A well-developed character is the key, essential part in relating the reader to the character of the story. In The Couple Next Door by Margaret Millar, a vivid description of Mrs. Rackham was given which aided in picturing how the lady must have looked when she was in pain and was suffering.


"Her fair skin was blotched with patches of red, like strawberry birthmarks, and her eyelids were blistered from the hear of her tears." (Hillerman 444)


In An Error in Chemistry, a very in-depth description of Old Man Pritchel was given which helped the reader to picture his appearance.


"A face rigid, furious, glaring at them through the glass for a second and then withdrawn, vanished, leaving an impression of furious exultation and raging triumph." (Hillerman 1)


A rather clear description of Paul's appearance was given in Paul's Case that allowed the reader to visualize how this story's protagonist must have looked.


"Paul was tall for his age and very thin, with high, cramped shoulders and a narrow chest. His eyes were remarkable for a certain hysterical brilliancy." (Hillerman 8)


The development of the characters, but most importantly, the protagonist, is the most essential of a mystery short story.


The tales found within' the book, The Best American Mystery Stories of the Century, are extremely high quality mysteries because they all contain the key elements of setting, symbolism and animal imagery, and characterization which are vital to a mystery story. Setting is used in a mystery to set mood and create atmosphere, which helps develop the plot. Symbolism is an asset used in a mystery short story to give a better description of the events by creating an example many people can relate with. Characterization is the most important element that a mystery can possess because a well described protagonist allows the story to be entertaining and easy to follow. High quality mystery stories all possess the elements of setting, symbolism, and characterization in order to be a great mystery story.

Ethics in Business Law


A very important and influential aspect of business is the way in which various enterprises execute their moral beliefs and incorporate them into their specific industry. The philosophical reflection upon this particular aspect of business is known as ethics, which has become an increasingly integral focus of society due to its recently discovered value. Since business is a commercial or industrial enterprise engaged in as a means of livelihood, strong ethics is especially vital because it is the conscious reflection on the integrity, credibility, and trustworthiness of that which is being assessed. Due to the highly competitive nature of today's market, companies must maintain high moral integrity in order to survive especially since strength in ethical values have such a drastic effect on consumer ratings, which will inevitably effect reputation and business. In order for a company to remain successful, it must recognize its faults and improve on them constantly. When contemplating ethics in business, focus is placed upon; key issues that arise which must be recognized in business, the benefits of strong ethics compared to the consequences of ethical misdeeds, and perspectives of ethics in business in the form of benchmark figures.


The major concerns that arise in business are related to the effectiveness of compliance policies and the influence of the management, the ultimate focus of the company and its relation to ethics, and the relationship of employee loyalty and ethics. Compliance policies refers to the established standard of ethical conduct that employees within a company must always follow. Effective compliance policies maintain a level of ethicality that employees must meet in all aspects of their business, and the reason why these compliance policies are effective is due to their enforcement and the importance placed upon them by the management (Institute of Business Ethics 4). The influence of the management on the employees is like that of a parent on a child; both must foster strong ethical values and serve as role models for the subordinate whether an employee or a child. This will encourage and influence the employees to follow the same ideal which will most likely create a more responsive staff. The focus of the company is always demonstrated during employee training; if the employer is only focused with sales and revenues and does not address ethics then the employee will develop a disregard for conduct use any means necessary to meet their superior's goals. However, if the employer focuses on incorporating strong ethics into everyday business, then the employee will follow suit and do the same. Lastly, its is proven that the loyalty of an employee to their company is directly related to their company's strength in ethics (Kuttner 7). Statistically, forty percent of employees who say their superiors are persons of high moral integrity are also truly dedicated to their company. Though this may seem low, it is considerably higher than the insubstantial six percent who are loyal to superiors with low moral integrity (Center for Business Ethics 1). These major issues in business ethics have been the ultimate success or the ultimate downfall of even the most powerful corporations and must not go unheeded.


There are numerous benefits of the utmost importance that a company can gain through strength in ethics and are essential in today's volatile market. Organizations that place a considerably high importance on ethical conduct are statistically more successful than companies who do not when comparing companies of the same trade (Acton ). Since the majority of potential customers believe that strong ethics are a necessity, these people obviously do not wish to associate themselves with persons of low moral integrity. Therefore, if a company places high importance on strong ethics and executes its compliance policies correctly, then its employees will be persons of high moral integrity and thus attract more business. The consequences of ethical misdeeds range drastically in severity depending upon the particular misconduct and who it effects. Companies cited for ethical misdeeds have suffered everything from damaged reputations and loss of business to decreased market values and demoralized employees (Kuttner 4). It is these devastating consequences that have resulted in business failure most often through bankruptcy which could quite possibly lead to criminal charges.


Perspectives of particular businesses on their ethical integrity are most commonly provided by unbiased benchmark studies, whose ratings are based upon employee and customer responses. Benchmark studies provide information on many aspects of business, and one of the many topics under question is the ethical conduct of a company. These studies are the results of various surveys given by multiple organizations and include perspectives on senior officers, ethical violations, and integrity of the workforce to name a few (Acton 6). These studies provide the general public with an ethics reference based on national averages to consult when dealing with any aspect of business and can have positive or negative effects on the industries in question depending upon their results.


Strength in ethics is obviously an extremely valuable asset to a successful company in any industry because its largest consequence is an overall increase in business, which is the true livelihood of any company. Companies must maintain a high level of moral conduct in today's unpredictable market because a superior reputation is one of the few things that can be created and maintained without effect by the uncontrollable. With able competition at its highest, a seemingly small aspect of business such as ethics is very often the deciding factor when considering multiple companies of strong bearing. The unforgiving effects of ethical integrity will overthrow companies with a disregard for morality, and thus effective standards of ethical conduct are inevitably the future of all successful companies in modern business.

If Sharks Were People


"If Sharks were people," asked the daughter of the innkeeper of Mr. E., "would they be nicer to the little fish than grown-ups are to us?"


"Of course," he answered. If sharks were people, they would have massive boxes built for the little fishes, with all kinds of foods in them, both meat as well as vegetables. The sharks would insure that the boxes would always have fresh water in them, and they would certainly meet all the measures of sanitation and health required. For example, if a little fish injured its fin, then the sharks would immediately provide a bandage, so that the little fish would not die before its time. So that the little fishies would not get depressed, there would also be huge water festivals, because happy fish actually taste better than sad ones.


Naturally there would be schools in these massive boxes, in which the little fishies would learn how to swim into the jaws of the sharks. For example, they would need geography courses, so that the little fishies could find the big sharks, who would be lazily lying about at various places in the ocean. But the main point of the schools would be in the moral training, the socialization of the little ones. They would be taught that it would be the greatest and most beautiful honor to offer themselves as a martyrs; and they would have to believe in the sharks, above all when the sharks promised to be working on a glorious future for the little fishies. The teachers would instruct the little ones to believe that this glorious future would be certain only if the little ones learned obedience to authority. Additionally, the little fishies would be taught to guard themselves against all low, materialistic, egoistic, and Marxist temptations and immediately inform the sharks whenever the little ones saw any of their friends display such tendencies.


Do my essay on If Sharks Were People CHEAP !


If sharks were people, there would natrually be wars fought among them, in order to conquer foreign fish boxes and little foreign fish. The wars would be led by the sharks' own little fishies, and the little fish would be taught that there was a big difference between them and the little fishies of other sharks, huge differences. The little fishies, all of whom would be kept relatively ignorant, would be informed through shark-approved media about what the foreign fish were up to, and therefore all schools of fish would remain silent to each other in their own language, since they were properly and accurately informed of all they needed to know by the sharks.


There would also be no need for the little fishies to get involved in anything of importance, since the sharks take care of them for their own good; and it would also be for their own good that the little fishies didn't mix with the foreign fishies. One never could tell how that might effect the various schools.


Each little fishy that killed another, foreign, other-language-speaking fishy in


the war would be given an honor and a medal made out of seaweed and told that he was a hero.


And naturally there would be an Art, if sharks were people. There would be beautiful pictures in which the sharks' teeth in their gleamingly neat rows would be portrayed, the insides of the jaws presented as pure and enticing pleasure gardens into which the heroic little fishies would so willingly be streaming, as if going intoxicated into an amusement park on a three-day pass.


There would certainly be a religion in the ocean, if sharks were people. In the churches named for sharks, they would teach the little fishies that life would really begin only when they were finally down inside the bellies of the sharks.


And the notion of egalitarianism among little fishies (as it is now) would cease. Some of the little fish would receive official posts and be made bigger, thus being placed above the others in status, which would suit the sharks just fine, since the sharks actually prefer larger portions per serving. And these bigger, post-given fish would be put in charge of keeping order and stability among the littler ones by becoming teachers, officers, engineers of fish boxes, and so forth.


In short, there would finally be a culture in the ocean, if sharks were people.

Accessible, light, easily worked and replaceable, wood is an essential element of basic survivalthe weapon, shelter and fuel. Wood is a hard, fibrous substance also known as xylem, which is the principal strengthening and water-conducting tissue found in the stems and roots of many plants, including trees and shrubs. The versatility of wood is basically attributable to its structure, chemical composition, and properties. Produced by many botanical species, it is available in various colours and grain patterns.


In contemporary times, in spite of technological advancement and competition from metals, plastics, cement, and other materials, wood maintains a place in most of its traditional roles, and its serviceability is expanding through new uses with the result that its consumption is steadily increasing. The long list of present wood uses includes products in which its natural texture is retained and others in which the wood is mechanically and chemically modified to the extent that its presence cannot be recognized. In addition to well-known products, such as lumber, furniture, and plywood, wood is the raw material for wood-based panels, for pulp and paper, and many other products, especially chemical derivatives of cellulose and lignin. Finally, wood is still an important fuel in much of the world.


The principal compound in cell walls is cellulose. Its molecules are linear chains of glucose, which may reach four microns in length. Orderly arrangement of cellulose molecules in fibrils (micelles) accounts for its crystalline properties. Noncellulosic constituents (hemicelluloses, lignin, and pectin) encrust the matrix among fibrils. Some hemicelluloses appear to serve as an important cross-link between the noncellulosic polymer8 and cellulose. Lignin is a complex substance that imparts rigidity to ceil walls. Pectins are important constituents of the layer between cell walls (middle lamella).


Cellulose and the other chemical constituents are contained in wood in the following proportions (in percent of the oven-dry weight of wood) cellulose 40-45 percent (about the same in gymnosperms and dicotyledonous angiosperms); hemicelluloses 0 percent i gymnosperms and 15-5 percent in angiosperms; lignin 5-5 percent in gymnosperms and 17-5 percent in angiosperms; and pectic substances in very small proportion. In addition, wood contains extractives (gums, fats, resins, waxes, sugars, oils, starches alkaloids, tannins) in various amounts (usually 1-10 percent, sometimes 0 percent or more). Extractives are not structural components but are deposited in cell cavities and intercellular spaces and may be removed (extracted) without change of wood structure. Most mechanical properties of wood are closely correlated to density and specific gravity. It is possible to learn more about the nature of a wood sample by determining its specific gravity than by any other simple measurement.


Order custom research paper on WHAT IS WOOD?


Density is the weight or mass of a unit volume of wood, and specific gravity is the ratio of the density of wood to that of water. Determination of the density of wood in relation to that of other materials is difficult because wood is hygroscopic, and both its weight and volume are greatly influenced by moisture content. In order to obtain comparable figures, weight and volume are determined at specified moisture contents. The standards are oven-dry weight (practically zero moisture content) and either oven-dry or green volume (moisture content above fiber saturation point, which averages about 0 percent).


PROPERTIES OF WOOD


MECHANICAL PROPERTIES


The mechanical or strength properties of wood measure its ability to resist applied forces that might tend to change its shape and size. Resistance to such forces depends on the magnitude and manner of application of the force. It also depends on various characteristics of the wood, such as moisture content and density. The term strength is often used in a general sense to refer to ail mechanical properties. The mechanical properties of wood include strength in tension and compression (axial and transverse), shear, cleavage, hardness, static bending, and shock (impact bending, toughness). Respective tests determine stresses per unit of loaded area (at elastic limit and maximum load) and other criteria of strength, such as modulus of elasticity (a criterion of stiffness), modulus of rupture (bending strength), elastic resilience, and toughness.


THERMAL PROPERTIES


Although wood expands and contracts with varying Temperature, these dimensional changes are small in comparison to the shrinkage and swelling caused by variation of moisture content. In most cases expansion and contraction are negligible and without practical importance; only temperatures below 0° C, (° F) may cause surface checks, and in living trees, unequal contraction of outer and inner layers may result in frost cracks.


PHYSICAL PROPERTIES


Familiarity with most kinds of wood makes it possible to identify them by their appearance. Some woods such as black walnut can he identified by their color others can be distinguished by their, odor. Many woods have a pronounced difference in color between sapwood and heartwood, whereas in others there is difference in color exposed to fire. In addition, the low heat conductivity of wood (high insulating value) makes it desirable for building construction. Heat conductivity is about two to two and a half times greater axially than transversely and increases with density and moisture content.


Colour This varies from the white of a holly tree to the red in redwood or black of an ebony.


Odour This is due to certain Chemical deposition the heartwood when it is more pronounced than sapwood.


Grain This is the direction of the wood fibers i.e. the alignment of the cells w.r.t. the axis of a tree. It can be described as cross, straight, interlocked, spiral curly, or wavy.


Texture This refers to the size of the cells in the wood & their proportion in unit volume; or simply, it is the uniformity of a woods surface. Texture can be fine (e.g. boxwood & sandalwood) or coarse (e.g. teak & sal).


Weight this depends on the density & hygroscopicity of the wood.


Density & specific gravity this is the weight or mass of a unit volume of wood, & specific. Gravity is the ratio of the density of wood to that of water. Differences in these quantities occur due to different proportions of wood substance (excluding the volume of cell humans & wall spaces) & the content of extractives.


Hygroscopicity wood is hygroscopic i.e. it exhibits on affinity for water and can absorb moisture. This Property varies among different species. The moisture content of cell walls varies from 0 to 5%. Hygroscopicity is of primary importance because all wood properties such as shrinkage, swelling, hardness, strength, heat producing capacity & resistance to decay depend on it.


Shrinkage and Swelling wood is subject to dimensional changes depending on its moisture content fluctuations. Shrinkage of the wood, proceeding that of the cell wall, occurs as moisture escapes from the wood structure & results in the molecules moving closer together. Swelling is just the reverse. These dimensional changes are anisotropic i.e. different in axial, radial & tangential directions. They may result in change of shape. Checking (cracks formation) warping, case hardening (release of stresses in resawing), honey combing & collapse.


ELECTRICAL PROPERTIES


Very dry wood is an excellent insulator But electrical conductivity increases with an increase in moisture content. Wood also acts as a dielectric i.e. although a non-conductor, it sustain the force of an electric field passing through it. Wood also exhibits the piezo electric effect i.e. electric polarization under mechanical shares & strain, in an electric field.


ACOUSTIC PROPERTIES


Wood can also produce sound by direct striking & can amplify or absorb sound waves originated from other bodies. The pitch of the sounds increases with larger dimension, lower moisture contents & higher density & elasticity.


TYPES OF WOOD


HARDWOOD


Timber obtained from angiospermous, or flower-bearing, trees that have broad leaves. Hardwood trees are deciduous, except in the warmest regions, and shed their leaves at the end of each growing season. Hardwood is the source of about 0 percent of the worlds production of lumber. The term hardwood is a classification of material, known originally from such hard European woods as beech and oak but actually including both the hardest and the softest of woods available. Many beautiful hardwoods include cabinet timbers such as American black walnut, oak, elm, yew, rosewood, teak, ebony, primavera, maple, satinwood, greenheart, and various mahoganies.


COTTON WOOD


Cottonwood includes several species of the genus populous. Most important are eastern cottonwoods, also known as Carolina Poplar and white wood, swamp cottonwood and black cottonwood. The heartwood of the three cotton woods, eastern, black, and swamp, is grayish white to light brown. The wood is comparatively uniform in texture, and generally straight grained. It is odorless when well seasoned. Cottonwood is used principally for lumber, veneer, pulpwood, and fuel.


MAPLE


Commercial species of maple include sugar maple, black maple, silver maple, red maple, boxelder, and big leaf maple. The sapwood of the maples is commonly white with a slight reddish-brown, tinge. Maple wood has a fine, uniform texture. It is heavy, strong, hard, stiff and resistant to shock and has large shrinkage. Maple is used principally for (lumber, veneer, crossties, distillation wood and pulpwood. A large portion is manufactured into flooring, furniture, boxes, and crates, Shoe lasts, handles, woodenware, novelties etc.


ASPEN


The heartwood of Aspen is grayish white to light grayish Drown. The sapwood is lighter colored and generally merges gradually into heartwood without being clearly marked. Aspen wood is usually straight grained with a fine, uniform texture. It is easily worked. This type of wood is lightweight and soft. It is low in strength, moderately stiff, moderately low in resistance to shock, and has a moderately high shrinkage.


ASH


Ash, black ash and Oregon Ash.


Commercial white ash is a group of species that consists mostly of white Ash and green ash. Blue Ash is also included in this group. White ash is particularly sought because of the Inherent qualities of this wood; it is heavy, strong, hard. Stiff, and is high resistance to shock. Because of these qualities, such tough Ash is used particularly for handles oars vehicle parts, and sporting goods.


Oregon ash has on the other hand somewhat lower strength properties, but is generally used for the same purposes.


The wood of black Ash runs considerably lighter in weight than that of white ash, and therefore, is sold as cabinet Ash, and is suitable for storage, furniture and shipping containers.


Hardwoods can be classified as


Deciduous Hardwoods


These trees lose their leaves in winter. They grow in warmer temperate climate (including the British Isles, Europe, Japan, New Zealand, Chile and Central America), and are slow growing and expensive.


Evergreen hardwoods


These trees keep their leaves all year round, and therefore grow more quickly and to a greater size. They are usually softer and easier to work with than deciduous hardwoods. The grow mainly in tropical and sub-tropical climates (including most of South America, Central America, India, China, Africa, Burma, India and East and West Indies).


SOFT WOODS


Soft Woods include firs, pines, spruce, and all conifirous timbers. They are characterized by distinct annual rings, but indistinct medullary rays, (groups of horizontally arranged cells radiation from the center towards the barks). Their traits also include light colour, straight fibbers, long steins of uniform section, long & narrow pointed leaves, exudation of issuing and mostly turpentine as well. soft woods are very strong for direct pull, but are weak in resisting thrust or shear.


Examples of softwoods (found mainly in India & Pakistan) are


CHIR


Himalayan softwood; easy to work; liable to surface and cracking unless protected against too rapid drying.


DEODAR


Has a natural preventative; light, moderately strong, easy to season & work; retains its shape well.


MANGO


Moderately staring; general utility wood; easy to season but liable to stain if not dived quickly; easy to work; & keeps its shape well.


WORKING WITH WOOD


Woodworking is defined as the process of constructing, or working with articles of wood, as in carpentry, joinery, cabinet making, and engraving. The different techniques include


WHITTLING


Woodworking techniques begin with the simple one of whittling. This is the using of a knife to cut away extra wood to achieve a form required by the craftsman.


TURNING


This is the fashioning of a piece of wood with a chisel while the wood is rotated on a lathe, much like the potters wheel. Most round forms such as the legs and arms of tables and chairs are formed in this way.


WOOD CARVING


The designing and decoration on a piece of furniture done by craftsmen using tools is the art of carving.


WOOD CUTS


In this process the artist cuts away the wood along the grain, leaving lines which when inked, will make the print in relief.


WOOD ENGRAVING


This process is similar to wood cuts, except instead of being done on a wood block cut out with the grain it is done cutting across the grain.


WOOD SCULPTURE


As wood is more perishable very few examples of early wood sculptures remain. The sculptor working on the piece of wood must carry a mental image or drawings of the finished product in three dimensions. The block to be worked on must first be marked out with chalk before the artist starts cutting away wood using a lot of different techniques.


WAYS OF JOINING WOOD.


The object of the joint is to fix two members together so that the joint has the greatest possible mechanical strength and is as unobtrusive as possible. Though there are many joints in use, they fall into a few basic groups, many being variations and elaborations of fundamentally simple ideas. Practically all are based on handwork, and with few exceptions most machine-made joints follow the traditional patterns; most joints rely to a considerable extent on a combination of mechanical fit and glue for their strength


GLUING OF WOOD AND MECHANICALLY FASTENING OF WOOD


Generally there are two ways of joining wood, gluing and fastening. Technically fastenings are considered to be more reliable than that of the glue. Of mechanical means of fastening, screws are the best, though a good joiner would pride himself in being able to make most things without a single screw in It. They are used for concealed fixings, for work which may have to be taken apart. Smaller nails, such as panel pins, are used for fixing small members, such as moldings, and sheet materials, like plywood. Their narrow heads are to be punched and puttied over. The joiner except for fixing lower- quality work does not use longer nails. Thus fastening can be done in a number of ways, such as with nails, spikes, screws, bolts, lag screws, drift pins, etc.


NAILS


Nails are the most common mechanical fastenings used in temporary and permanent constructions. There are many types, sizes, and forms of standard nail, and in addition many special-purpose nails. In general, nails have stronger joints when driven into the side grain than into the end grain of wood. Also nails should be preferably be used so that their literal resistance, rather than direct withdrawal resistance, is utilized.


SPIKES


Common wire spikes are manufactured in the same manner as common wire nails. They have either a chisel point or a diamond point and are made in length of 7 to inches; they have larger diameters than the common wire nails. The allowable withdrawal and lateral resistance formulas and limitations given for common wire• nails are also applicable to spikes, except that in calculating the withdrawal load of spikes, the depth of penetration should be reduced by two- thirds the length of the point.


DRIFT BOLTS


Drift bolts are driven into prebored holes of diameters 1/8th inches less than that of the bolts. The allowable load for a drift bolt in lateral resistance should not exceed that for an ordinary bolt of the same dimension. The drift bolts should be of greater length than the common bolt to make up for the lack of washes & nut.


WOOD SCREWS


The common types of wood screws have flat, oval, or round heads, their principal parts also include the shank, thread & core. Flat head screws are used if a flush surface is desired inheres oval & round head screws are used for appearance.


LAG SCREWS


These are used because they are highly convenient especially whose bolts are difficult to fasten & nuts on the surface are objectionable lag screws range from about 0, to 1 inch in diameter & to 16 inches in length.


CONNECTOR JOINT


Timbers can be joined by metal or other types of connectors. These types include split-ring, soothed, shear plate, bulldog, claw plate, circular spike, & kubler wood-dowel connectors. The latter was originally made of cast iron but now of oak & is very satisfactory


CROSS BOLTS


Cross bolts placed at or near the end of timbers joined with connectors or at intermediate panel point will provide additional safety. They may also be used to reinforce members that have, through change in moisture content in service, developed checks to an undesirable degree.


SPECIAL FASTENERS


Wood workers use a variety of metal fasteners besides nails and screws. All kinds of special bolts, screws, hooks, plates, and braces are used to fasten objects together. Many of the fasteners are designed for use with metals. Many of special fasteners used by wood workers are briefly described here.


CARRIAGE BOLTS


They have oval heads and are square just below the heads. The square part sinks into the wood thereby preventing turning once the bolt is set in the hole. These bolts are used in rough construction and for joints that do not show.


SHEET METAL SCREWS


Sheet metal screws, or tapping screws are threaded the full length of the screw. They are used to attach materials such as plastic and sheet metal to wood. They are especially handy when attaching thin pieces.


CORRUGATED FASTENERS


They are used when appearance is not a factor. They provide a quick way of joining stock. They will not make strong joints. They are staggered and driven at an angle to the grain.


MENDING PLATES


These are flat pieces of steel. They come in several shapes And Sizes. Mending plates are used to reinforce and repair broken and weakened joints. They are usually used in places where they will not show.


ADVANTAGES OF JOINTS


1n the wood working process, the importance of joints cannot be denied. In fact it is almost impossible to work with wood without a proper command on joint- making. Moreover, the joints used are of various kinds; the application of a joint in the production of something is decided keeping in view the requirements and purpose of the product.


The Dowelled joint for instance, is a very strong and easily by machine. To ensure the true alignment, a tongue is an advantage, and this necessitates a double row of dowels, which gives the greatest strength. No end grain is exposed as with an ordinary tenon. The dowels, and less timber is used than for a tenon joint.


The combed joint is essentially a glued joint. The glue must take the whole of the stress; so the larger the area of glued sauces the better. Three glue surfaces are most common, but more can be made it the section is thick enough for each tenon to be of workable thickness.


The combed joint does not hold itself in position while glue is setting. Clamping has to be arranged so that the parts are held in their true positioning.


WOOD DESTROYING AGENTS


MOLDS AND STAINS


Molds and stains are confined largely to sapwood and are of various colors. Little direct staining of the wood is caused by molds, since the discoloring caused by them is largely superficial and is due far the most part to cottony or powdery surface growths. Which vary from white or light colors to black. Such blemishes often are easily brushed or surfaced off.


Stains penetrate into the sapwood and cannot be removed by surfacing. The discoloring of the wood occurs as specks, spots, streaks, or patches of varying intensities of color. The so-called °blue stains, which vary from bluish to bluish black and brown, are the most common although various shades of yellow, orange, purple and red are sometimes encountered. The exact color ot the stain depends on the infecting organisms and the species and moisture condition of the wood.


INSECTS


The worst of these are termites, popularly called 'white ants'. The insects live in a colony, each colony having a queen, much larger in size, which alone lays millions of eggs during her lifetime of about ten years.


WOOD-BORING BEETLE


This beetle is capable of biting holes into the wood the larva is directly responsible for the damage brought about by its endless tunneling while it feeds on the wood substance, leading to the eventual collapse of the wood structure.


Then there are wood wasps much less harmful, the larvae of which bore tunnels in the dead wood of Deodar, Spruce and Fir, extending for several inches.


MARINE BORERS


There are two types of these; one popularly called 'Teredo navalis', these do not actually feed on the wood but bore tunnels into it for shelter from their enemies. The other species called 'Limnoria' feed on wood and in a short time, wood becomes honey-combed with tunnels, and ultimately collapse.


USES OF TIMBER


Wood and its products have a huge variety of uses all over the world. Some products are used directly but most wood products serve as intermediate materials that undergo processing and are manufactured into final products or structures.


ROUND WOOD PRODUCTS


Poles , posts and certain mine timbers are products in round forms. Poles are used in telecommunication lines e.g. telegraphs, telephones, or as pilings i.e. foundations for buildings, and posts are used in fences highway guards and various supports.


SAWN WOOD


The main sawn wood product is lumber. It is used for heavy construction. Railroad ties are also made by sawing. This lumber is the product of the sawmill and is produced in varying sizes from logs.


VENEER


This is a thin sheet of wood that is uniform in thickness. Veneers are used primarily for plywood and furniture but are also used in toys, containers, matches, battery separations etc.


PLYWOOD AND LAMINATED WOOD CONSTRUCTIONS


These are glued wood products. Plywood is panel product manufactured by glueing together veneers to both sides of a single veneer or solid wood. In addition to flat panels, plywood is manufactured in curved form used for boats, furniture etc.


Laminated wood is used in beams, columns and arches for buildings, boat keels, aircraft carrier deckings, helicopter propellers and mine sweepers.


PARTICLE BORAD


This is manufactured from particles of wood glued together. It contributes to greater wood utilization by permitting the use of residues of other wood using industries and of harvesting operations in forests.

WHAT IS METAL ?


Metals are usually crystalline solids, which constitute almost 75% of all chemical elements found in nature. Mostly, they have simple crystal structures distinguished by a close packing of atoms and a high degree of symmetry. The art and science of extracting metals from their ores and modifying the metals for use, is known as metallurgy.


The most abundant varieties in the Earths crust are aluminum, iron, calcium, sodium, potassium, and magnesium. The vast majority of metals are found in ores (mineral-bearing substances~, but a few such as copper, gold, platinum, and silver frequently occur in the free state because they do not readily react with other elements.


PROPERTIES OF METAL


• High density and melting point.


• Malleable and ductile (i.e. can be drawn into wire).


• Thermal conductivity.


• Electric conductivity.


• Lustrous (when polished).


• Sonorous (i.e. can be beaten into sheets).


• High tensile strength.


MANUFACTURE OF METALS


Most metals are found as minerals (compounds of the metal mixed with earthy material (gangue). The mixture is called an ore. Metals can bee manufactured from their sources e.g. sulphides, oxides, nitrates, chlorides, suppurates etc. By electrolysis or reduction. The ore is concentrated after mining to eliminate worthless materials as possible. One of the most important methods for concentrating sulphide ores is known as the ore flotation process.


In this process the finally pulverized ore is mixed with water, to which one or more chemical frothing agents are added. When air is blown into the mixture froth is produced and the earthy material is wetted and sinks. The sulphide ore particles, however, rise to the surface in the froth, where there can be skimmed off the surface. After the addition of acids to break up the froth, the concentrated ore is filtered and dried.


The metal is then manufactured in the following way


ROASTING OF THE ORE


In this process the concentrated ore is heated in a controlled amount of air. The purpose of this operation might be


1. To convert the sulphide ore into its oxide prior to reduction of the oxide to the metal itself. At this stage impurities such as arsenic are driven off.


. To covert the sulphide ore partially into its oxide, which is then reduced to the metal by further reaction with the sulphide ore.


SINTERING


This involves heating the material until partial fusion occurs and larger, more easily handled material is obtained.


SMELTING


This involves the reduction f the ore to the molten metal at a high temperature. Substances called fluxes are added, their function being to combine with the gangue to forma liquid slag that floats on the surface of the molten metal.


REFINING


The purpose of refining metals is to make them as puree as is necessary. Numerous techniques include the following


• Electrolytic refining


Electrolytes can be used to purify metals e.g. copper is purified electrolytically by making the impure copper the anode of an electrolytic cell, which contains an electrolyte of copper sulphate solution and a thin strip of pure copper as the cathode. By the appropriate choice of voltage, pure copper is transferred from the anode to the cathode.


• Zone-refining


This method is applied on a very small scale to produce metals and some non--metals in an extremely high degree of purity. The method depends upon the principle that an impure molten metal will deposit puree crystals on solidifying. The metal, in the form of a rod, is melted over a very narrow region at one end; this molten region is transferred from one end of the rod to the other by slowly moving a furnace. Impurities collect in the molten region and are swept to one end of the metal.


TYPES OF METALS


SODIUM


• Physical properties


The metal is soft and silvery coloured it is an extremely good conductor of heat and electricity and less dense than water. because it rapidly transits and loses its slivery appearance in air, it is generally stored under oil.


• Chemical Properties


The metal is very reactive; sodium reacts with water with increasing vigor.


Na(s) + H O(1) ------------ Na + OH (aq) +H(g)


It reacts with a variety of non-metals when heated to give oxides sulphides, hydrides, etc. e.g.


Na(s) + S(s) ---------------(Na+) Sa (s)


(Lithium alone reacts with nitrogen to give the nitride (Li+)N-, since both the lithium and nitrogen atoms are very small and the resulting nitride has a very compact structure with a high lattice energy).


The metal burns in a steam of hydrogen chlorideand reacts with ammonia when heated e.g.


Na(s) + HCI(g) ------------ Na+CI-(s) + H(g)


Na(s) + NH(g) ----------- Na+NH-(s) + H(g)


CALCIUM


• Physical properties


The metal is very hard. Ti is a good conductor of heat and electricity. When pure it is silvery coloured, but quickly transits on exposure to air because an oxide film covers its surface. It has a high melting & boiling Pt).



• Chemical Properties


The metal is very reactive. It decomposes water with increasing vigor to give the hydroxide and hydrogen e.g.


Ca(s) + HO(1) ------------- Ca+(OH)-)(aq)/s) +H(g)


At a suitable temperature it combines with a variety of non-metals to give oxides, sulphides,halides nitrides; and hydrides.


Ca(s) + H(g) ----------- Ca+(H-)(s)


With dilute hydrochloric and dilute sulphuric acids it gives a saltand hydrogen e.g.


Ca(s) + H+C1-(aq) ------------ Ca+(C1-)(aq)+H(g)


ALUMINUM


Aluminum is a light metal possessing considerable strength, yet is malleable and ductile. It isnot very reactive because normally there is a very thin oxidelayer on its surface. Whenthis oxide layer is removedby rubbing with mercury,the metal reacts rapidly with moisture in the air, forming a moss-like growth of aluminum hydroxide, and becomes very hot in the process.


It combines directly with oxygen, sulphur, nitrogen and the halogens when heated to a sufficiently high temperature.


Aluminum reacts with moderately concentrated hydrochloric acid to give the chloride and hydrogen. The pure metal is not readily attacked by dilute sulphuric acid, but with concentrated HSo4 it gives the sulphate and sulphur dioxide. It is made passive by nitric acid and this has been attributed to the formation of an impenetrable oxide layer on its surface. It is attacked by sodium hydroxide solution with the liberation of hydrogen.


A1(s)+OH-(aq) + 6HO(1) -------- A1 (OH)4 (aq) + H (g)


IRON


Pure iron is a silvery coloured metal with a melting point of 155 C. It is easily magnetized when placed inside a coil carrying an electric current, but loses its magnetism when the current is switched off. A number of non-metals combine with it on heating, e.g. oxygen, the halogens, nitrogen, sulphur and carbon; iron filings burn in oxygen with a shower of bright sparks forming iron (III) oxide, FeO, but in the massive form iron is coated with a layer of magnetic oxide of iron, FeO4. Pure iron does not action of dry air or air-free water; however the combined action of air and water results in the formation of rust, essentially hydrated iron (III) oxide. At red heat iron is attacked by steam with the formation of magnetic oxide of iron and hydrogen. Dilute non-oxiding acids such as sulphuric and hydrochloric acids attack iron, with the formation of iron (II) ions, Fe+ (aq), and hydrogen; in the presence of air the iron (II) ions are slowly oxidized to iron (III) ions, Fe+(aq), concentrated nitric acid renders the metal passive. Impure irons such as wrought iron & cast iron are also very useful.


COPPER


Copper has a melting point of 108 C and a density of 8.4 g cm-. It is an attractive golden coloured metal, being very malleable and ductile. The metal is slowly attacked by moist air and its surface gradually becomes covered with an attractive green layer of basic copper carbonate. At about 00 C it is attacked by air and a black coating of copper (II) oxide forms on its surface; at a temperature of about 1000 C copper (I) oxide is formed instead. Copper is also attacked by sulphur vapour, with the formation of copper (I) sulphide, and by the halogens which form the copper (II) halide.


The metal is not attacked by water or steam and dilute non-oxidising acids such as dilute hydrochloric and dilute sulphuric acid are without effect in the absence of an oxidising agent. Boiling concentrated hydrochloric acid attached the metal, with the evolution of hydrogen.


Hot concentrated sulphuric acid attacks the metal and so too does dilute and concentrated nitric acid.


Cu(s) + HSO4(1) ------------- CuSO4(s) +HO(1) + SO(g)


Cu(s) + 8HNO(aq) ----------- Cu(NO)(aq) +4HO(1)+NO(g)


USES OF COPPER


Copper is used for the windings of dynamos and for conveying electrical power, it's a useful metal for the construction of condensers for chemical plants and car radiators. Finely divided copper is used as an industrial catalyst.


SILVER


Silver has a melting point of 61 C and a density of 10.5 g cm . It is a white lustrous metal and is very malleable and ductile; it is the best conductor known. The metal is resistant to attack by air and mositure, although the presence of hydrogen sulphide results in the black stain of silver sulphide. Steam and dilute non-axidising acids are without effect on the metal; however, it is attacked by hot concentrated sulphuric acid and cold dilute nitric acid, with the formation of silver (I), Ag+(aq), ions.


Ag(s) + HSO4(1) ------- AgSO4(s) + SO(g) + HO(1)


Ag(s) + 4HNO(aq) ------- AgNO(aq) + HO(1) + NO(g)


USES OF SILVER


Concentrated nitric acid produces mainly nitrogen dioxide. Silver is still used in coinage as an alloy with copper. Large quantities are also used for the manufacture of tableware and jewelry. The deposition of silver on cheaper articles is carried out to produce silverplated cutlery.


GOLD


Gold has a melting point of 106 C and density of 1. g cm-. It is extremely malleable and ductile, e.g. it can be beaten into sheets no thicker than 0.000 01 mm and pulled into wire of extremely small diameter; its thermal and electrical conductivities are very high. The metal is one of the most unreactive elements; it is not attacked by air, water or steam, and the common mineral acids leave the metal untouched.


USES OF GOLD


In view of its lack of chemical reactivity and its attractive bright yellow colour, gold is used in the manufacture of jewelry. Gold is sold by the carat. Cheaper articles are made by plating copper alloys with gold, using an electrolytic process.


ALLOYS OF METALS


An alloy is a substance prepared by adding other metals or non-metalsto a basic metal, so as to obtain certain desirable qualities. Thus it can be considered as a uniform mixture of two or more metallic elements.


Some Common alloys of metals include brass, bronze, duralumin, steel and stainless steel.


BRASS


This is an alloy copper (60 8%) and zinc 0-40%. It is stronger to more malleable than copper. It has greater workability due to a lower melting point and an attractive appearance.


BRONZE


This contains copper (0-5%), and tin (5-10%). It is very strong, and resistant to chemical attack. It is also very shiny in appearance.


Bronze is used to make coins, medals, and sculptures.


DURALUMIN


This contains aluminum (0-5%), copper (-5) and magnesium (-5%) and carbon (0.15 1.5%). Steel is more malleable and ductile than iron. It is much harder and stronger & can withstand great stress & strain.


Steel is used in the construction of ships, cars, bridges to machinery.


STAINLESS STEEL


This is a mixture of iron (0-5%), and chromium & nickel (5-10%). It is very hard & resistant to corrosion. Has a very lustrous appearance. Stainless steel is used to make cutlery, Tools & surgical instruments.


TECHNIQUES OF METAL WORK


The techniques of working metal developed very slowly and for long only in connection with the progress of metallurgy itself the mining of a mass of metal from the earth. Scholarly opinion now holds that the first steps were taken after the adoption of settled ways of life-represented by agriculture and stock breeding-in northeastern Iran, the first area in which this occurred. In this area were native copper, metal-bearing rocks, malachite, and abundant timber, which allowed a steady progress of discoveries to be made. The Iranians learned the essentials of metalworking by using native copper variations of the techniques were applied to other metals as they were recognized. A diffusionist theory is now generally accepted The techniques were developed in northeastern Iran, but the products, and possibly also the producers, gradually were carried by trade and emigration to other areas. They went to the valley civilizations of Mesopotamia, across western Persia and through the east Mediterranean littoral to Egypt, across North Africa, and on into Spain. A second route lay from western Iran into Anatolia and then across the Hellespont to Europe. This diffusion began in about the 5th millennium BC and was continued for over 000 years.


EARLY TECHNIQUES


The earliest metalworking was of copper, perhaps as early as the th millennium. Using small nuggets of native copper picked up in streams or from the ground. These nuggets were presumably at first considered a special kind of attractively colored stone, and by grinding and beating-methods already used for working stones, flints, and obsidian-they could be shaped into ornaments.


ANNEALING


The newt step was the discovery, about 5000 BC that these special stones could be worked on with repeated hammering if the mass was heated to a full red color and cooled from time to time, and that this kept the metal soft and workable. Ordinary wood fires produced sufficient heat for this process, called annealing. Repeated hammering without annealing will cause the metal to become too hard and brittle, with resultant jagged tracks.


SMELTING


The next discovery came after the development of the closed two-chamber pottery kiln, which produced a far greater heat than the open fires adequate for the earlier low-fired pottery. This took place probably before 4000 BC and led, after some 500 years or so, to the smelting first of small pieces of native copper, malachite (which under certain conditions will render into copper), and finally large amounts of copper ores, in furnaces that initially resembled the two-chamber pottery kilns. It was not until copper ores were smelted that any significant increase in the supply of copper and copper products could take place.


CASTINGS


Most metals are produced by melting and casting in molds. The mould may be shaped and dimensioned to the final size or it may simply be a prism which is intended for further processing. When intended for turther processing the metal will solidify in a rather coarse grain structure and will contain a number of casting defects such as porosity, shrinkage and cavities.


HOT WORKING


The working of metals and alloys depends upon plasticity. They can be heavily deformed, especially in compression, without breaking. For steel structural members the most usual method is by hot rolling between shaped rolls at temperatures around 1000 C. after rolling, the members are left to cool naturally and, during this process, a heavy film or iron oxide develops. Thus steel sections deliverd as rolled end to be shot blasted or sand blasted before receiving any protective coating.


Many familiar articles, e.g. crankshafts, are forged into shape.this involves placing a hot blank into one half of a shaped mould and then impressing the other half of the mould on to the blank. This is generally done under impact using such methods as drop forging, die stamping etc.


COLD WORKING.


Because of their ductility many metals and alloys can be bold worked, that is to say, shaped at temperatures below the recrystallization temperature. This create an immense number of dislocations and the metal becomes harder and its yield point is raised. Metal sheets area shaped into cups, bowls or motor car parts by deep drawing or stretch forming.


JOINING


Although adhesive bonding may be used for joining metals, the ecumenist methods are welding, brazing, soldering or inserting metal pins such as rivers and bolts.


BRAZING AND SOLDERING


Both processes involve jointing by means of a thin film of a material which has a lower melting point than that of the parent material and which, whenmelted, flows into the joint, oftenby capillary action, to form a thin film. A good brazed or soldered joint should have a strength which is not too different from that of the parent material.


PINNING


For some materials (such as cast iron and wrought iron) bolting or rivetingare the only possible ways of making joints. Both rely on friction-the tightened bolt forces the two members together and the friction between nut and bolt at the threads holds it in place. In riveting, the hot rivet is hammered into prepared holes. As it cools it contracts and develops a tensile stress which effectively lochs the members together. High strength friction grip (HSFG) bolts used in structural steelworks combine both aspects the bolt is prestressed to a given level and this tensile prestress acts in the same way as does the tensile stress in a river.


WELDING


The welding technique᠐, which involved inter-layering relatively soft and tough iron with high-carbon material, followed by hammer forging᠐produced a strong, tough blade. In modern times the improvement in iron-making techniques, especially the introduction of cast iron, restricted welding to the blacksmith and the jeweller. Other joining techniques, such as fastening by bolts or rivets, were widely applied to new products, from bridges and railway engines to kitchen utensils. Modern fusion welding processes are an outgrowth of the need to obtain a continuous joint on large steel plates. Riveting had been shown to have disadvantages, especially for an enclosed container such as a boiler. Gas welding, arc welding, and resistance welding all appeared at the end of the 1th century.


The first real attempt to adopt welding processes on a wide scale was made during World War I. By 116 the oxyacetylene process was well developed, and the welding techniques employed then are still used. The main improvements since then have been in equipment and safety. Arc welding, using a consumable electrode, was also introduced in this period, but the bare wires initially used produced brittle welds. A solution was found by wrapping the bare wire with asbestos and an entwined aluminium wire.


The modern electrode, introduced in 107, consists of a bare wire with a complex coating of minerals and metals. Arc welding was not universally used until World War II, when the urgent need for rapid means of construction for shipping, power plants, transportation, and structures spurred the necessary development work. Resistance welding, invented in 1877 by Elijah Thomson, was accepted long before arc welding for spot and seam joining of sheet. Butt welding for chain making and joining bars and rods was developed during the 10s. In the 140s the tungsten-inert gas process, using an inconsumable tungsten electrode to perform fusion welds, was introduced.


In 148 a new gas-shielded process utilized a wire electrode that was consumed in the weld. More recently, electron-beam welding, laser welding, and several solid-phase processes such as diffusion bonding, friction welding, and ultrasonic joining have been developed.


GAS WELDING


Gas welding is a non-pressure process using heat from a gas flame. The flame is applied directly to the metal edges to be joined and simultaneously to filler metal in wire or rod form, called the welding rod, which is melted to the joint. Gas welding has the advantage of involving equipment that is portable and does not require an electric power source. The surfaces to be welded and the welding rod are coated with flux, a fusible material that shields the material from air, which would result in a defective weld.


ARC WELDING


Arc-welding processes, which have become the most important welding processes, particularly for joining steels, require a continuous supply of either direct or alternating electrical current. This current is used to create an electric arc, which generates enough heat to melt metal and create a weld.


Are welding has several advantages over other welding methods. Arc welding is faster because of its high heat concentration, which also tends to reduce distortion in the weld. Also, in certain methods of arc welding, fluxes are not necessary. The most widely used arc-welding processes are shielded metal arc, gas-tungsten arc. gas-metal arc, and submerged arc.


SHILEDED METAL ARC


In shielded metal-arc welding, a metallic electroude, which conducts electricity, is coated with flux and connected to a source of electric current. The metal to be welded is connected to the other and of the same source of current. By touching the tip of the electrode to the metal and then drawing it away, an electric arc is formed. The intense heat of the arc melts both parts to be welded and the point of the metal electrode, which supplies filler metal for the weld. This process, developed in the early 0th century, is used primarily for welding steels.


GAS-TUNGSTEN ARC


In gas-tungsten arc welding, a tungsten electrode is used in place of the metal electrode used in shielded metal-arc welding. A chemically inert gas, such as argon, helium, or hydrogen, is used to shield the metal from oxidation. The heat from the arc formed between the electrode and the metal melts the edges of the metal. Metal for the weld may be added by placing a bare wire in the arc or the point of the weld. This process can be used with nearly all metals and produces a high-quality weld. Moreover, the rate of welding is considerably slower than in other processes.


GAS METAL ARC


In gas-metal welding, a bare electrode is shielded from the air by surrounding it with argon or carbon dioxide gas or by coating the electrode with flux. The electrode is fed into the electric arc, and melts off in droplets to enter the liquid metal that forms the weld Moat common metals can be joined by this process.


SUBMERGED ARC


Submerged-arc welding is similar to gas-metal arc welding, but in this process no gas is used to shield the weld. Instead, the arc and tip of the wire are submerged beneath a layer of granular, fusible material formulated to produce a proper weld. This process is very efficient but is generally only used with steels.


RESISTANCE AND THERMITE WELDING


In resistance welding, heat is obtained from the resistance of metal to the flow of an electric current. Electrodes are clamped on each side of the parts to be welded, the parts are subjected to great pressure, and a heavy current is applied briefly. The point where the two metalin welding breaks or seams in heavy iron and steel sections. It is also used in the welding of rail for railroad tracks meet creates resistance to the flow of current. This resistance causes heat, which melts the metals and creates the weld. Resistance welding is extensively employed in many fields of sheet metal or wire manufacturing and is particularly adaptable to repetitive welds made by automatic or semiautomatic machines.


In thermite welding, heat is generated by the chemical reaction that results when a mixture of aluminum powder and iron oxide, known as thermite, is ignited. The aluminum unites with the oxygen and generates heat, releasing liquid steel from the iron. The liquid steel serves as filler metal for the weld. Thermite welding is employed chiefly


SAFETY MEASURES WHEN WORKING WITH METAL


A brief outline of the safety recommendations for arc welding and the cutting processes is as follows


1. Keep the working area and floor clean and clear of electrode stubs, scraps of metal and carelessly disposed tools.


. See that the cable connections are tight and that they do not become hot.


. Never look at an electric arc with the naked eye.


4. Never weld while wearing wet gloves or shoes.


5. Never leave the electrode holder on a table or on the table or in contact with a grounded metallic surface.


6. Operate arc welding machines and equipment only in clean dry locations.


7. Always work in a ventilated area


8. Goggles with suitable lenses and protective clothing are recommended as protection against harmful rays, as well as against flying sparks, splattering metals and hot metal.
