Introduction to Mathematical Thinking
Keith Devlin is going to be offering another instance of his online course, Introduction to Mathematical Thinking, starting on March 4. The idea is to serve as a bridge between high school mathematics— which focuses on solving specific types of … Continue reading
A computerchecked proof of the odd order theorem
Big news: a proof of the FeitThompson Theorem (also known as the “odd order theorem”) has been completely formalized and verified by a computer, using the Coq proof assistant! Wait, what? Huh? you’re probably thinking. Well, let me unpack that … Continue reading
More factorization diagrams
My post on factorization diagrams from a month ago turned out to be (unexpectedly) quite popular! I got ten times as many hits as usual the day it was published, and since then quite a few other people have created … Continue reading

Wythoff’s game at ThreeCornered Things
I’ve really been enjoying Zachary Abel’s series of posts on Wythoff’s game [Wythoff’s Game: Red or Blue?; A Golden Observation; The “Fibonacci”est String; Wythoff’s Formula], over on his blog ThreeCornered Things. The Fibonacci numbers show up in the strangest places! … Continue reading
Nature by Numbers
This has been making the rounds of the math blogosphere (blathosphere?), but in case you haven’t seen it yet, check out Cristóbal Vila’s awesome short video, Nature by Numbers. Especially appropriate given that I have been writing about Fibonacci numbers … Continue reading
