The "Fibonacci" Sequence Was Actually Discovered In India 1000 Years Earlier
The sequence of numbers 1, 1, 2, 3, 5, 8, 13, etc was described by Fibonacci around 1200 AD. The Indian mathematician Pingala found the sequence at least 1,000 years before (probably 200 BC) while analyzing Sanskrit poetry. This video describes how the sequence arises from metrical analysi

Richard K Guy - Numbers, Pictures, and Richard Guy & The Leaning Tower of Pingala - G4G12 April 2016
The leaning tower of Pingala is a tipped up arrangement of what is commonly known as the Pascal triangle. It leads to the many properties of second order recurring sequences, which are, among other things, divisibility sequences.

A Tribute to Berlekamp, Conway, Guy, Graham, and Randi - G4G14 Apr 2022
In the long four years between G4G13 and G4G14, we lost some towering figures from the G4G community. It is hard for many of us to see how we can go on without them, but their legacy will live on. In this tribute session, we honor Elwyn Berlekamp, John Conway, Richard Guy, Ron Graham, and

Some of the history I describe at the end is not quite accurate- Al Kwarizmi did not calculate the size of the earth- this had been done long earlier by Eratosthenes & Ptolomy. Kwarizmi wrote an updated version of Ptolomy's geography book, and made super-accurate computations of the latitu
