Archimedes Essay, Research Paper


Archimedes was a Greek mathematician and


scientist. He was born in Syracuse, Sicily in the year 287 B.C. He was


educated in Alexandria, Egypt. Due to the lack of information about Greek


mathematics, many Greek mathematicians and their works are hardly known.


Archimedes is the exception. Archimedes was very preoccupied with mathematics.


For instance, he often forgot to eat and bathe because of his always wanted


to solve problems.


He found areas and volumes of spheres,


cylinders and plain shapes. He showed that the volume of a sphere is two-thirds


of the volume of the smallest cylinder that can contain the sphere. Archimedes


was so proud of this concept that he requested that a cylinder enclosed


a sphere, with an explanation of this concept, be engraved on his grave.


Archimedes also gave a method for approximating pi. He was able to estimate


the value of pi between 3 10/71 and 3 1/7. Math wasn?t as sophisticated


enough to find out the exact pi (3.14). Archimedes was finding square roots


and he found a method based on the Greek myriad for representing numbers


as large as 1 followed by 80 million billion zeros.


One of Archimedes accomplishments was his


creation of the lever and pulley system. Archimedes proved his theory of


the lever and pulley to the king by moving a ship, of the royal fleet,


back into the ocean. Then, Archimedes moved the ship into the sea with


only a few movements of his hand, which caused a lever and pulley device


to move the ship. This story has become famous because Archimedes said,


“Give me a place to stand on and I will move the earth. Another invention


he invented was the Archimedean screw. This machine was built for raising


water to highland areas in Egypt that could not receive water directly


from the Nile River. This device is still used today for irrigation purposes


even is some countries today.


The most famous story of Archimedes life


involves the discovery of Archimedes’ Principle. The story begins when


King Hieron asking a goldsmith to construct a gold wreath to the immortal


gods. After some time, the king came to suspect that the wreath was not


pure gold but rat

her filled with silver. In order to end his suspicion,


the king asked Archimedes to determine whether the wreath was pure gold


or filled with gold without destroying it. Archimedes agreed to try to


solve the king’s problem. Then one day, while he was taking a bath, Archimedes


noticed that the water level rose in the bath as he entered the water.


Archimedes was so excited by this discovery that he jumped out of his bath


and ran naked through the streets yelling, “Eureka, Eureka!!? meaning,


I have found it. Archimedes had discovered that a body immersed in a fluid


displaces its weight of fluid. This principle in turn helped Archimedes


prove that the gold wreath was not solid gold.


Archimedes was probably most famous during


the time he lived because he developed techniques defenses for Syracuse


against the Romans. Syracuse was able to hold off the invasion for three


years due to Archimedes?s inventions. He invented catapults, which hurled


blocks of stone, and cranes, which dropped large stones on approaching


ships. Also, he developed scaling ladders, which helped soldiers climb


over enemy walls. Archimedes can use mirrors to reflect sunlight on the


adversarial ships burning them.


The Romans finally invaded Syracuse and


overtook the city Archimedes was drawing circles in the dirt. When a soldier


commanded Archimedes to surrender, Archimedes instead drew his sword and


told the soldier that he wanted to finish the proof he was working on before


surrendering. The soldier became angry and killed Archimedes. This shows


that Archimedes was so committed to his expertise that he took the chance


to dying in order to work on his last problem. Archimedes was so thoughtful


with the study of math, and because of it, it led to many important discoveries


and principles for us today.


What helped me the most were encyclopedias,


books and the Internet. I think I got enough information to basically point


out the general account of it. I can?t really think of anything I can do


differently. I learned that Archimedes was a very significant man of his


time that was perfected pi, his principles and his inventions. He was far


beyond any man?s thinking capabilities.
