Pi Day 2021:
Who needs high tea when you can have pi glee?
Sunday, March 14
2:00 pm to 3:00 pm ET (New York)
Pick up your fun Pi Day items — including the ever-popular pizza pi wheel — at MoMath: shop.momath.org/pi-items.
Don't forget to set your clocks forward on Sunday, March 14, for the beginning of Daylight Saving Time.
2:00 pm ET (New York): "Probably Pi?"
While it is impossible to write pi in its entirety, various methods exist to generate better and better approximations. In this crowd-sourced experiment, we see how the law of large numbers lets us confidently approach pi by using probability. By randomly dropping a needle onto a set of lines, we can converge on pi experimentally, without the need for direct measurement. Come help us generate data to see how many digits of pi we can get — the more, the mathier!
2:30 pm ET (New York): "What is the value of Pi?"
Throughout history, people have tried to compute the exact value of pi. Ancient Babylonians believed that pi = 25/8, Egyptians thought that pi = (16/9)^2 = 256/81, while the Indiana state legislature almost passed a bill in 1897 to legislate the value of pi. We know now that pi cannot be computed exactly; join us as we use geometric constructions to find rational approximations.
To fully participate in both sessions, have the following handy:
- Pen or pencil
- Two pages of graph paper
- Compass (for drawing circles)
- Ruler
