- 11. Pi Ponderings Did you know that: “0” is the only digit that does not appear in the first 32 digits of pi? The earliest known reference to pi is in a Middle Kingdom papyrus scroll, written around 1650 B.C. by the scribe Ahmes. The millionth digit of pi is 1. William Jones first gave the Greek letter “pi” its current mathematical definition in 1706.
- 12. Pi Ponderings continued In 1610, German Ludolph van Ceulen completed his calculation of pi to 35 decimal places. This approximation was engraved on his tombstone, and pi is still referred to in Germany as the Ludolphine number. The digit 7 occurs 7 times in the first 99 digits of pi!
