🧵 My 3rd book is now out! It is on the fascinating history of math. How did people throughout history think about math?What problems did they care about? How did they express them? How were they solved? This book includes a lot of historical math. a.co/d/gsoNKxP

René Descartes, 1637:

@l__zOz__l I did not know! Very excited!

@LongFormMath They are planning to make this movie you know!

Emmy Noether

A Hamilton-style play about Évariste Galois would be perfect

@HeNordlinder Lovely!

@LongFormMath We have that quote posted outside the maths department at Stockholm University, where Kovalevskaya was active

“It is impossible to be a mathematician without being a poet in soul.” —Sofia Kovalevskaya

Was so focused on checking his math that I didn’t see the guy in the back without a head?! Is this some sort of gorilla-suit experiment??

@miniapeur Me too!

@LongFormMath I hope you do a book on functional analysis one day!

Btw I have slowly but surely been making videos over the content of my Proofs book. This week I began chapter 4. Check it out and subscribe if you’re interested! Eventually I will go through all the other books too. Proofs by Induction and Dominoes: youtu.be/X2IgwuKlIVs

@VergaraLautaro Personally, I think “straightforward” is only a little overused :-)

@LongFormMath I thought it was "straightforward"

“Obviously”

Fun Fact: when he wrote it, the equal sign had not yet been invented

Endre Szemerédi (b. 1940 in Budapest, Hungary) is a Hungarian-American mathematician specializing in combinatorics and theoretical computer science. Szemerédi proved Szemerédi’s theorem in 1975: any subset of the integers with positive upper density contains arbitrarily long arithmetic progressions, resolving a 1936 conjecture of Erdős and Turán. He introduced the Szemerédi regularity lemma in 1978, stating that every sufficiently large graph can be partitioned into a bounded number of parts such that most pairs of parts induce regular bipartite graphs; this became a fundamental tool in extremal graph theory. In 2012 he received the Abel Prize “for his fundamental contributions to discrete mathematics and theoretical computer science, and in recognition of the profound and lasting impact of these contributions on additive number theory and ergodic theory.” He has authored over 200 papers and received awards including the Rolf Schock Prize in Mathematics (2008).

Students like this warm my heart. It’s effortless to be dishonest, and yet they make an honest effort anyways!

Btw on July 4, 1776, Leonhard Euler was 69 years old, was almost completely blind, and was still writing over one paper a month at a very high quality. For example, in 1776 Euler wrote his landmark memoir giving the modern formulation of linear and angular momentum in mechanics. And in another paper he introduced and studied double zeta values. GMOAT things.
