this is not how you state theorems, you don't state the assumptions inline way above and say "f will be x" and then write sentences starting (and ending) with mathematical notation saying things like N_p \geq 2

what the hell is the ultimate Cauchy theorem

for example, he proves this proposition with strong assumptions and a weak conclusion, while a much stronger statement is true (for principal value sums) for arbitrary analytic f with |zf(z)| = O(1). Then he assigns a bunch of sum problems that are unsolvable with the weak version given in the book

typesetting is nightmarish, everything is some long in-line derivation which randomly introduces 3 or 4 important definitions, generally not in their own environment, which is then used 4 or 5 pages later. exercises in chapter 11 end up using some random prop in chap 6

it's an absolute disaster, random stuff shoved in at every opportunity, most prominently long historical tidbits of various mathematicians. theorems and propositions are not clearly stated or mathematically well-posed, definitions are given extremely implicitly or omitted.

barry simon's complex analysis textbook is, across several axes, one of the worst textbooks I've ever read from a pedagogical standpoint.

not beating the allegations (chose to present Minkowski bound for my final presentation in Galois theory, as the lone discrete probabilist in the class)

this is a regular meal for like 30% of the world but go off...

among all the ways this is deranged and alien (sesame noodles is not a weeknight meal? cannot buy cilantro?), why does it is also lowkey Racist for no reason

I like it when people tell me about the television shows they're watching. I haven't watched a television show in years and have seen maybe 7 in my life but I like hearing about them. tell me what the brigertons are doing.

Just experienced the most intense tear gassing of my life by federal officers outside the ICE facility in Portland where marchers gathered. There was no fast exit as they indiscriminately threw loads of gas and flash bangs. Children were in the crowd screaming. @oregoncapitalchronicle.com

Really important read

I’m sorry but I still can’t get over the fact that the analyst Jean Leray was captured by Nazis in 1940 and knew it was time to become Goblin Wizardman & this is why the world contains sheaves

Man shot in Minneapolis by federal agents identified as VA nurse: ‘He wanted to help people’ Alex Pretti, 37, worked in the ICU at the Minneapolis VA Health Care System and had assisted on scientific research

Alex Pretti took care of veterans as an ICU nurse. “He was a super nice, super helpful guy – looked after his patients," said @dimitridrekonja.bsky.social, who worked with Pretti both at the hospital and on scientific research. "I’m just stunned.”

gave my first conference talk and it went really well!!! so much positive feedback from probabilists I really really admire

nice hit tweet Tim

Why not just say branch...

I can't keep getting away with this (but like actually, I can't keep getting away with this lol)

Maybe it's bad that I'm a math PhD student who doesn't know what div, grad, curl are

The most unsubtle, heavy-handed claims made by pomo academic types have turned out to all be true. Gender is a relation of domination that requires constant, affirming witness. Capitalism will require extractive colonial relations. There’s no subtlety. Every day is like a 101 seminar at Oberlin.

Passage from Lang's Algebra stating that "monoids exist in nature"

Love mathematicians' notion of "exists in nature"

At least 60,000 murdered in Sudanese city, which resembles ‘a slaughterhouse’ Satellite evidence shows extent of paramilitary massacre in El Fasher

So, El Fasher looks like one of the worst single event atrocities to happen this century so far, but the evidence has come in such a trickle it seems to only now be getting verified

seeing my cat and my friends at home for the first time since moving to US for PhD. so very excited

You spent....
• 70 hours thinking about new projects instead of completing old ones
• 42 hours gleefully deluded by an incorrect proof
• 30 hours assuming the wrong hypothesis
• 9 hours thinking about statements that ended up being equivalent to the Yoneda lemma
