Once upon a time I imagine people were very happy to think of Lie algebras as “infinitesimal groups,” but presumably when infinitesimals fell out of favor this interpretation did too. In this post I’ll record an observation that can justify thinking of Lie algebras as groups in a strong sense: they are group objects in a certain […]

Sébastien Bubeck mentioned it on his blog here is his new introduction to convex optimization entitled: Convex Optimization: Algorithms and Complexity", AbstractThis monograph presents the main complexity theorems in convex optimization and their corresponding algorithms. Starting from the fundamental theory of blackbox optimization, the material progresses towards recent advances in structural optimization and stochastic optimization. Our presentation of blackbox optimization,

I got an email a few days ago telling me that my MathJobs account will be deleted in a month after nearly two years of inactivity. The 4 years I spent on the job market have given me a Pavlovian … Continue reading →

By A.K. Whitney, journalist. In 2009, Whitney went back to school to find out, once and for all, if journalists really are as bad at math as they fear they are; her blog about the experience, Mathochism, runs on Medium three days a week. … Continue reading →

image by Alberto G.. CC BY 2.0 Almost all American colleges used to require standardized test scores from the SAT or ACT. The scores are meant to assess student ability across many educational experiences, public and private schools alike. But the test scores have been criticized as being biased. There are large gaps in scores … Continue reading Why have 850 colleges made the SAT/ACT optional for admission? Game Theory Tuesdays

We are working on a unit on polynomials. Today's target  dividing by long division and synthetic division.I knew we would spend about half of our class time in direct instruction, I do ... you do, dividing polynomials. We discussed the Factor Theorem and the Remainder Theorem. Our challenge question ...But it is the second half of class when students were excited, engaged, and enthused! It's a dot and boxes game ... with a division problem in each square. As

that moment when u open a topology book to some weird shit like this which your brain now registers as completely plausible and reasonable from all the damage your math major has done to your mind and for a fleeting, fleeting second of lucidity u wonder to urself “wtf am I doing with my life?”
Oh man, you should’ve included the name of the theorem that allows all this. It’s called “the Hairy Ball theorem”, and I’m not

Coffee And Bacon: The Math Mistake That Makes Health Studies So Misleading: Faye Flam:The problem is not with your math. This kind of percentage figure is used more often to impress consumers with the importance of a study than to enlighten us about our health. In this case, there’s a critical piece of information missing.

KBeauty is the first test: there is no permanent place in the world for ugly mathematics.~Godfrey Harold HardyThe 335th day of the year; 2335 is the smallest power of two which equals the sum of four consecutive primes. *Prime Curios This seems astounding to me, that such a huge number would be the first. There are 67 primes smaller than 335, and so 335 is divisible by the number of primes less than itself.. How common is that for integers. EVENTS1729 Euler/Goldbach […]
