Archimedes Essay -- biography biographies bio

Archimedes (287BC-212BC) was truly one of the greatest mathematical minds of all time. The discoveries and inventions of Archimedes formed the basis of many of the fundamental concepts of modern physics and mathematics. Born 287 BC Archimedes grew up in the thriving commercial hub of the port city of Syracuse, Sicily. His father, Phidias, was an astronomer and mathematician and it is thought his family enjoyed the life of aristocracy. Very little is known about his life, what is has been reported by the Roman writer and historian Plutarch. He studied for a short time in Alexandria, Egypt. Alexandria was a great place of learning, and at this time Euclid studied there and undoubtedly influenced Archimedes thinking. At the end of this study, Archimedes returned to Syracuse were he spent the rest of his life actively discovering and explaining important concepts. He is one of the few geniuses in history that enjoyed his own fame in his lifetime. Both his peers, his king, and even his enemies respected him for his work. Most of Archimedes writings were lost in the burnings of the Library of Alexandria. What we know of Archimedes treatises is from three manuscripts. Two of them have been lost in history (one was last heard of in 1311, another in 1550) and the third is The Archimedes Palimpsest, now at The Walters Art Museum in Baltimore. (PW) The Archimedes Palimpsest is very important and contains many ideas of Archimedes. During the medieval ages, the parchment on which his work was written was re-used as a prayer book.

It is currently being refurnished at Rochester Institute of Techn... ... Wikipedia. Archimedes Spiral. Last updated.19 March 2007. http://en.wikipedia.org/wiki/Archimedes_spiral Wikipedia.

Acquiring Political Power under a Principality Essay

In The Prince, Machiavelli writes his analysis of how to acquire and sustain political power under a principality. It is his understanding of human nature and the ability to maintain control over people that make up the base for all of the other theories he puts forth. Machiavelli is able to recognize what it takes to balance the citizens somewhere between happy and scared, so to keep them from revolting while appearing united and strong discouraging others form invading. Thucydides shares a similar view of human nature, as he sees all people as being motivated by fear, honor, and self interest. Machiavelli and Thucydides both demonstrate how a ruler can use many aspects of human nature to their advantage when ruling a state. The†¦show more content†¦This passage provides the reasoning why leaders are safer feared than loved. When danger is close at hand, people will turn on you if they do not fear the punishment they will be handed. Thucydides shared a very similar view of human nature using different reasoning as to why humans are of a self centered, amoral nature when faced with tragedy. Thucydides showed the similarities in human nature during the plague and during the war. He observed that in the plague and in wartime, humans become self serving individuals and give up their morality and reason. Although Thucydides and Machiavelli wrote their books two thousand years apart, the similarity in their views showed that human nature had not changed. The fact that their works are still refered to today suggests that human nature has not in fact even changed much today. Machiavellis first focus has to do with the changing of rulers in a state and what the most effective strategy of taking over is. The ideal way of taking over is dependent on what the situation in the state was before and how the new ruler came into power. Thucydides states for a private citizen to become prince through their own ability is very tough to do, but when they are successful it is easy to keep their power.
