Exactly!!!

This timeline feels like the last season of a prestige TV show. I can’t get over the irony that humanity is signing its own environmental death warrant by getting companionship from a computer.

Nikola Tesla would consider Elon Musk a moron.

Mathematics: Sudoku as a Graph

Sudoku cells are like dots, and the rules are like lines connecting them, showing which cells can't share numbers. This allows mathematicians to use graph theory to analyze and solve the puzzle.

This week, I recorded 4 new videos on the isomorphism theorems.

I do them in a nonstandard order, but I hope to convince you that it's the most natural.

Please share, because every algebra student (and instructor!) should find this helpful!

U.S. early-career researchers struggling amid chaos Uncertain funding, government firings, and distressed universities hit vulnerable groups especially hard

A whole generation of early career scientists and physician-scientists, including colleagues and myself, are particularly vulnerable to these funding freezes and cuts, with jobs and careers depending on federal grants.

“Displacing poverty, centring wealth” – @wealtherty.bsky.social on the need for a new articulation of the problem of wealth inequality. Rather than poverty, should we foreground “wealtherty”? #LSEInequalitiesBlog

This one goes out to all the Americans

We are sorry. Take him out, Please

In order to get rid of Income Tax which is what Donald Trump really wants to do, he will need to put a Tariff of 250% on everything, including the things made in the USA.

That is exactly what he will try to do.

If you support Mexico, like.
If you support Canada, RT.

Say no to Donald Trump and Elon Musk and watch their empire collapse.

I made two new #VisualAlgebra videos about semidirect products, that are done even before I introduce the concept of a normal subgroup. Check them out! #MathSky

Lecture 2.9: Semidirect products, intuitively

New #VisualAlgebra video!

Lecture 3.2: Subgroup lattices

There are LOTS of fun pictures in here. I'm obviously biased, but I really think that this will be greatly beneficial to anyone taking or teaching abstract algebra. Check it out!
