­The Association for Mathematical Research Association for Mathematical Research has announced a new $50,000 Prize in the Mathematics of Artificial Intelligence. It will be awarded for research performed in the last 10 years in mathematics relevant to Artificial Intelligence and Machine Learning, or in AI

It seems that the AAUP has decided that academic boycotts are now legitimate. If you are so inclined, you can sign a petition in opposition to their new position. docs.google.com/document/u/0/d…

I’m very sad to learn that Pierre Cartier passed away yesterday. A long time ago, when I was a depressed 22 yo math student who was going through very hard times and had just abandoned his PhD, Cartier helped me get back on track. He tutored me during a full transition year,

I first heard about this result at Sarnak's conference, where Calegari spoke about it. Blown away. So so cool, both the result, and especially the method! With the wonders of the internet, you too can be blown away; here's Calegari's lecture: ias.edu/video/arithmet…

I was sent Bourgain’s video from when he won the Shaw Prize. Can’t believe this was already 14 years ago, how time flies… youtu.be/apbNY9IuuOQ

I’m giving some lectures on a History of Math at Princeton University this term. Here is Lecture 1; a broad overview, some discussion of number systems, and an analysis of the famous YBC 7289 clay tablet: youtube.com/watch?v=ZSk63k…

Fun aside: Imagine trying to solve the equation: 2 * 7^2 - 4 * 7 - 3 = 0, where the unknown is “7”. That cognitive dissonance is what it would be like to do algebra (even in this modern, compressed form), if Fibonacci et al hadn’t brought the Hindu-Arabic numerals to

A vignette on using AI for research math: I wanted to add a little example in a paper I’m working on, something combinatorial, with graphs that needed to be computed and then drawn. It would have likely taken me 3 hours to figure out the complete classification, remember the

I have recently written a new curriculum for 5-18 mathematics. I think the approach to curriculum design is unlike anything that currently exists. I also think it is precisely what we need. I will publish a full discourse shortly. But first, I would like to stress test my

This was so fascinating. I had a teflon knitting needle on @ISS and charged it by rubbing with my Russian fur boots. Then I directed water droplets from a syringe towards the charged knitting needle and this is the resulting dynamics. The droplets, due to charge forces, go

Lecture 2 is posted: youtu.be/k8J4eA2xsVE “We hold these truths to be self-evident” We discuss the direct line from mathematical epistemology (what mechanisms we use to determine TRUTHs) and issues therein, to the preamble of the US Declaration of Independence. My claim is

An interesting side discussion here was: who gets to determine whether a claimed PROOF is correct? (I was trying to make the point that they should never merely accept what I’m saying; they should wrestle with the ideas presented until they themselves believe them to be true

Lecture 3 is posted: youtu.be/Ot5RMgV7k8A Theorem: Pianos do not exist! That is, we discuss Pythagorean music theory (how you can “predict” the overtone series just from prime number multiples of frequencies), the Pythagorean comma, equal temperament tuning, and Hippasus
