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

number.
