Donald Knuth's 25th Annual Christmas Lecture: Pi and The Art of Computer Programming
Donald Knuth, Professor Emeritus
2019

The number π appears thousands of times in The Art of Computer Programming, in many different contexts. Dr. I. J. Matrix has remarked that its digits, “when properly interpreted,” actually convey the entire history of the human race! [See page 41 of Volume 2.] This lecture will examine many interpretations of those digits, both proper and improper.

Professor Knuth is the Professor Emeritus of the Art of Computer Programming at Stanford University. Dr. Knuth's classic programming texts include his seminal work The Art of Computer Programming, Volumes 1-3, widely considered to be among the best scientific writings of the century

A genius in so many ways.
A century from now,
reality stars will be forgotten,
and institutes will be named after him.

Dear Stanford University Team, please send Dr Knuth in Europe, so that a maximum of people can have the honor to meet him. God bless him.

28:35: Galle of Art of Computer Programming. It contains dozens of puzzles. The emphasis of the book is on how to create the puzzles, rather than how to solve them.

One tiny mistake: pi in octal is 3.11037552421026... which indeed matches ""But I, I KNOW the octonal facts about pi..."". But he quoted it as "31103552" @22:19, leaving out the 7.

3:48 - At first glance, Pi is a random number. However, we can notice curious repetition patterns, i.e. with the number 26 repeating twice in the first 22 digits.
