Pi Measurement Challenge at the Great Circle Earthworks

Pi Symbol
March 12, 2016
1:00 pm - 4:00 pm
Great Circle Earthworks 455 Hebron Rd, Heath,OH 43056

This is a collaborative outreach event organized by mathematician Niles Johnson (OSU Newark) and historian Richard Shiels, director of the Newark Earthworks Center.  Additional support has been provided by the Ohio State STEAM Factory.  If you have further questions, please contact Niles.

The number π (pi) is the ratio of circumference to diameter in a circle.  This ratio is the same for all circles, and is just a bit larger than 3.

On Saturday, March 12 2016, we will visit the Great Circle to measure its circumference, measure its diameter, and divide!  Participants of all ages are invited to help with the measurement and learn more about the history and mathematics of this spectacular site.  Experts at the Newark Earthworks Center will join us and explain how the mathematics of this site connects it with other sites in Ohio.

How close will our measurement be to the true value of π?  Join us to find out!  We’ll announce the results publicly on π day, Monday March 14.
