| The History of Circular Constant ?=3.14Tue, 30 Dec 2008 23:53:57 -0800 by cosmosk1This movie got No.1 at the Most Viewed of YouTube Japan Dec 20-26 2008.The Circular Constant ?=3.14 The circular constant shows that the circumference is what times of diameter. It was decided 3 in Old Testament. It is known that 3.125 in Babylonia and 3.1604 in Egypt 3700 years ago from the record of the clay board and papyrus. It is said that ? was begun to use by Leonard Euler who was a mathematician of Germany in 18 century. The circumference is called periphery in Latin and the initial p contains ? in Greek And then ? was used. Archimedes calculated the circular constant as follows. He drew right hexagon which borders inside the circle 1 in diameter and calculated the surrounding length. Nest, he calculated the surrounding length of the right 12 polygon and continued to the right 96 polygon. And he also calculated the surrounding length of the right hexagon to the right 96 polygon that borders outside the circle. Then he calculated that the circumference is bigger than the length of the right 96 polygon that borders inside the circle, 3.140845 and smaller than the right 96 polygon that borders outside the circle, 3.142857. In other case, Socyushi of China in 5 century, Rudolf of Germany in 16 century, Shigekiyo Muramatsu and Kazutaka Seki of Japan in Edo period calculated as the same way of Archimedes. Shanks of England calculated it below decimal point 707 digit in 1873 and it was used for long time. Now it is calculated below decimal point 1,241,100,000,000 digit by computer.
