Geocache Description:

This is the fourth cache in my finite mathematical series. I am a math teacher by day. I thought a cache series dedicated to math would be a good way to educate the public.

A short history of Pi

Around 2000 BC the Babylonians made the observation that the ratio of a circle's circumference to its diameter was roughly 3. In 225 BC Archimedes of Syracuse made a great advancement in expressing pi as a fraction. He knew pi was between 223/71 and 220/70, and so he reduced it to 22/7. This ratio works out pretty well.

In 1706, an English mathematician introduced the Greek alphabet pi (p) to represent the said value. However, in 1737, Euler officially adopted this symbol to represent the number.

It wasn't until 1768 that Johann Lambert proved pi was irrational (the exact value cannot be written as a fraction, or as a decimal it does not terminate or repeat). The first 20 decimal places are 3.14159265358979323846... To see more visit http://www.joyofpi.com/pi.html

Pi is used in all formulas associated with circles, spheres, and cylinders. Besides everyday geometry calculations, the value of pi is also used in numerous scientific equations including genetic engineering, measuring the ripples, super strings, normal distribution and so on.

The cache is a camoed bison tube hidden down the road from where a pizza joint that made me think of pi once stood.
