Recording of Pi Day 2021: Pi by night

This is a recording of a live-streamed event that took place on Sunday, March 14, 2021.

Appropriate for all ages.

Join MoMath’s Distinguished Visiting Professor, Alex Kontorovich, for an exploration of pi.  What does pi have to do with circles?  How can we be sure that pi is bigger than three…or smaller than four?  How can the power of pi surprise us when we look at everyday household items?  And how can we use everyone’s favorite food to learn more about this amazing number?  Join us to find out…and bring your own pizza pi!

The following materials may be helpful but are not required:

  • a pizza pie and a pizza wheel or knife — we will be both cutting and eating the pizza!
  • a string, dental floss, or a thin strip of paper cut from the long side of a sheet of printer paper
  • an assortment of cylindrical household containers such as a:
    • tennis ball can
    • tuna fish can
    • soup can
    • soda can
    • water bottle
    • thermos
    • pasta canister (spaghetti container)
