In between Max constantly begging me for attention I've been studying algebraic geometry occasionally. Anyway this random proof feels really elegant to me.
Most of page 194 of Gortz and Wedhorn's book Algebraic Geometry I: Schemes.

But anyway it kinda works now 😤 I also spent a long time trying to get the text in the diagram to be the same size as the mathjax text, but I literally just couldn't fix it. Oh well.

Still skipping the hell out of these webinars, but also wtf is the current Gmail interface?? Why can I only see *two letters* of the sender's name??? And why are the buttons at the bottom so huge?? Lmao
A screenshot of an email from McGill university titled "Register for our upcoming Pre-Arrival webinars", also demonstrating the horrible Gmail UI.

Wtf!
rak1507: I'm not American but if I was I'd be slightly unhappy about my taxes subsidising people to eat junk food maybe people will have to get a job or eat healthily, not the end of the world syusim: If I have enough money to pay for other people's food who can't afford it and still get by just fine, and I don't want to do it, that would make me a bad person I don't know how to explain that it's good to care about other people rak1507: I used to feel the same way until I volunteered at a food bank/mutual aid organisation, which caused me to become slightly disillusioned. There were entire families who had essentially developed learned helplessness, and were entirely reliant on external support, and then despite receiving thousands of pounds in food every month, they were extremely picky and ungrateful We will only eat x brand of cereal, we don't eat fruit, etc Can't be a good thing long term

theyre calling it the most utterly swagless theorem of all time
Theorem 5.15 from Gortz and Wedhorn, which is a generalization of the Noether normalization theorem

Reviewing the basics of p-adic numbers for fun
On the left, my e-ink notepad with a calculation of the first few terms of the 2-adic representation of 1/3, and on the right, Neukirch's book Algebraic Number Theory open to the introduction to p-adic numbers.

Yves Engler released his platform today and it is actually incredibly good. If you're Canadian I highly encourage you to read it and be astounded by page after page of banger policies. Here's a few favourites.
Establish Affordable Housing Tribunals: ● In order to reduce rent increases and protect tenants, housing tribunals will be established. Rent will be adjusted to income tested thresholds being no greater than a third of income for tenants. ● Ban no-cause evictions. ● Implement a national rent freeze. ● Guarantee free legal counsel for tenants. Public Grocery Network: ● Nationalize large grocery chains under a cooperative, non-profit model by amalgamating existing chains to break corporate price-gouging, end price collusion and ensure Canadians in food deserts have access to fresh, quality food at affordable prices. End Corporate Influence: ● Ban corporate donations and lobbying influence over public policy. Abolish Billionaires through Expropriation Without Compensation: ● The nationalization of key industries without compensation is the only way forward. Canadians have spent decades giving subsidies and handouts in a corporate welfare scheme that is compensation enough.

Quora question: "atheists, imagine you're going skydiving with a Christian baby. Suddenly the baby tells you he won't open his parachute until you renounce atheism and accept Jesus as your lord and savior. What would you do?
