Joy of Pi

Sir Cumference

Check out my Pi Day list on I’m just starting with this bookstore and I love it! It supports local bookshops. Personally, I think you should check books out of the library, and then if you love them and want to add them to your home library, find a used copy locally.

Pi in the past

  • About 2000 BC, Babylonians used π = 3 1/8. Egyptians used π = 256/81 = 3.1605.
  • Archimedes used a spiral to square the circle sometime in the third century BC.
  • Isaac Newton discovered calculus and calculated pi to 16 digits in 1666.
  • In 1873, William Shanks published his calculation of pi to 707 digits. But in 1945 D.F. Ferguson found Shanks’ calculation wrong from the 527th place on. Then he took a year using a desktop calculator to calculate pi to 808 digits.
  • In 1996, the Chudnovsky Brothers computed over 8 billion digits of π using a supercomputer they built in their apartment from off-the-shelf parts.

Trivial trivia

If a billion digits of pi were printed in normal-sized font, it would be over 1200 miles long.

If Pi day were actually celebrated correctly, it would never end.
