Join us at the Great Circle in Heath, OH for the 2016 Pi Measurement Challenge!

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.


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



Where: Newark Earthworks, 455 Hebron Rd, Heath, OH 43056

When: Saturday, March 12, 2016; 1pm – 3pm

Who: All members of the public are invited to observe and participate!
