Pi Day Celebrations at Explorit

Pi Day celebrations are coming to Explorit Science Center a little early this year. You can catch all the math fun on Sunday, March 13 from 12:00 to 4:00 p.m.


The Greek letter Pi signifies the ratio of a circle’s circumference to its diameter. The number Pi is a mathematical constant whose decimal representation is never ending, but it’s first five digits are 3.1415, so every March 14th celebrates this geometric joy.


Pi has been in use since ancient civilizations. It was calculated to five digits in India and to seven digits in China in the fifth century C.E. It may have been used to help plan the construction of the Egyptian pyramids.


But it wasn’t until the 18th century that Pi got its name after the sixteenth letter of the Greek alphabet. William Jones published the letter Pi in reference to a fraction of a circle’s circumference in 1706 in his work New Introduction to the Mathematics.


Forty years later, Leonhard Euler repeated this use in a much more widely circulated text, and Pi caught on. It’s been a standard name in Western mathematics ever since.


Celebrate this auspicious arithmetical occasion with Explorit Science Center, appropriately located at 3141 5th St. in Davis. On Sunday, March 13 we’ll have a whole afternoon full of spherical fun, for the special admission price of just $3.14 (free to all Explorit members).


The festivities begin at noon with circle fun ongoing throughout the day. Sidewalk-Chalk It Up to Math by drawing and measuring your own circles. Discover Pi with LED tape-lights. Or test out the water columns in our Exploration Gallery with the Sphere Drop to explore the area of various objects.


And don’t miss “Mathful of Pi”, an interactive math exploration in our West Wing. It’s an awesome opportunity for some incredible, innovative math experiences!


Or bring your own bike to find out What’s the Deal with Wheels? Use a bike “calculator” to measure how fast you’re pedaling and discover how Pi can help you track your bike’s speed.


Plus, enter the drawing to win one of six certificates for a free fruit pie from Ikeda’s Fruit Stand. Come on out and celebrate some math this March with Pi Day at Explorit!
