Pi fun facts
Why pi? Beautiful in its simplicity, pi (pi = periphery) is the relationship between the perimeter of a circle (the circumference) and the distance across that circle (the diameter). For any circle, the principle is without exception universal — meaning it's always the same whether it be applied to a merry-go-round, a dinner plate, or a bicycle wheel.
For years the ancient Greeks struggled with rational numbers (those that could be written as a simple fraction) to arrive at the concept of pi. It was only later discovered that pi is an irrational number. Not crazy, mind you, but it does go on for infinity and can't be corralled into a corner.
Today, no one exactly knows who came up with the recipe for pi, but the symbol for pi was first used in 1706 by William Jones,
and later made popular by Swiss mathematician Leonhard Euler
Since then, pi has always been an under-appreciated concept -- except for physicists and mathematicians who truly admire its beauty.
To make up for pi's shabby treatment, the first Pi Day was held at the San
Francisco Exploratorium in 1988 when visitors were invited
to participate in Pi-related antics and activities. Later,
all were invited back to a celebration to be served - you
guessed it - a slice of apple
one of the museum's
on-site physicists the "Prince of Pi" Larry Shaw, is duly recognized as the founder of Pi Day.
