Students celebrate Pi Day


By Bryon Graff

MOSINEE (WAOW) -- Thanks to a Swiss mathematician, and more than a trillion digits, a Greek letter is celebrated into infinity.

On this 3-14 date, Pi Day is a hit in math classes everywhere. Pi represents the ratio of the circumference of a circle to its diameter.

Mosinee students mark the occasion with a piece of pie.

"Pi Day is the celebration of the number Pi," said math teacher Bob Isberner. "We often celebrate on March 14th because those are the first three digits of Pi, 3.14. Some schools will celebrate at 1:59 because those are the next digits in sequence."

According to, the symbol for pi was first used in 1706 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.
