Happy National Pi Day!
This marks the 25th anniversary of Pi Day. How do you celebrate? Do you enjoy eating your favorite pie or do you find pleasure in solving difficult math equations? Some people like to dress up as Einstein since 3/14 is his birthday. Maybe you can watch a movie based on Pi?
History of Pi.
The ancient Babylonians (ca. 1900–1680 BC) calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. The Egyptians (ca.1650 BC) calculated the area of a circle by a formula that gave the approximate value of 3.1605 for pi. The first calculation of pi was done by Archimedes of Syracuse (287–212 BC). He approximated the area of a circle by using the Pythagorean Theorem to find the areas of two regular polygons. Archimedes showed that pi is between 3 1/7 and 3 10/71. William Jones began using the Greek letter π in the 1706. and the use of the symbol was popularized by Leonhard Euler in 1737. So what about Pi Day? It was founded by physicist Larry Shaw in 1988 where he and his staff marched around a circular room and then proceeded to eat fruit pies. In 2009, the U.S. House of Representatives passed a non-binding resolution recognizing March 14 as National Pi Day.
Now that you have had your lesson for the day…go enjoy your Pi!
