The Kelly criterion says you should take green if your net worth is over $10k.
Out of Context Human Race@NoContextHumans
What you choosing?
English
@GarrettPetersen That seems too aggressive. You should probably take red unless your net worth is at least 1 million already.

What was the 10-year period in which the least important stuff happened since 1870?
Indonesia
@QiaochuYuan Yes. Claims of discrimination or oppression that are controversial (to put it mildly) when applied to the US are just true in many other parts of the world. The places most in need of wokeness are the ones most impenetrable to it.

like this is just wild, wtf

so far non-american (i've seen korean, japanese, russian) gender discourse seems heavily on the side of the women and it's not even close. the women are complaining about not being treated with, like, basic human dignity and respect, and the men are... huge fucking assholes?
QC@QiaochuYuan
started the day with russian tweets being like "how wonderful to make friends from all around the world and discover that people don't hate russia actually!" but i have now found myself at the korean tweets being like "it's clear now that we need to unalive all men"

@bryan_caplan Both correlate with the things determining moral value, one very weakly, one very strongly. What does “matters” mean?
English
Citizenship matters for a person's moral value.
Species matters for a creature's moral value.

@Uppity_Blacky @Aella_Girl Have you used these models and talked to people especially software engineers — in the last 2 months, using best available models? Far away is much closer now.
English
@Aella_Girl I wish people actually used these models and talked to people especially software engineers. These models are dumb GPT is the smartest but it's still far away.

I’ll soon send off my book manuscript to my editors. Are there any pop culture examples about smell you desperately want me to include? Think film, (fictional and reality) tv, books, trends, news stories, products, quotes etc. Just want to make sure I’m covering all my bases!

@Golovanov_ammoc Not a comment on Aluffi vs Lang, but this is just a categorical definition of Ker, right? Like in the above snippet from Vakil’s “The Rising Sea”.
English
This is the kind of insight that makes Paolo Aluffi a legendary expositor better than overhyped and completely dry Serge Lang’s book on algebra.
Yaashaa Golovanov@Golovanov_ammoc
Sergei Makarevich, a protege of AMMOC, goes to Stanford Online High School, and attended Stanford’s prestigious SUMAC. He joined AMMOC because he felt he needed to be challenged far above his the then curriculum. I initiated him on Aluffi’s Algebra. We are closing the 2nd chapter

Anecdote about math learning through LLMs:
I'm trying to figure out Fourier transforms, and for the life of me this proof doesn't make sense. It "works" but just feels totally unintuitive to me. But, while showering, I got an idea for a new, more intuitive proof strategy...

@IsaacKing314 You are mixing levels of description. Natural numbers are not “amount you can have of something”, they are “amount you can have of something you can count, naively speaking” - or whatever similar you phrase translates “isomorphism classes of finite sets” ;)
English
If you accept the argument that 0 is a natural number because you can have 0 of something, then you must also consider 3+5i a natural number, because Schrodinger showed us that you can have 3+5i of something.

P.S. Сегодня я впервые послушал концерт Дениса Чужого. Денис оказался своим - настолько хорошо зашли некоторые его шутки. Как вот эта, про российско-американские отношения, гуманитарную помощь, гордость и москвичей - глубоко срезонировала, от сетапа до панчлайна ;)

@lucaslugao @francoisfleuret Sorry, meant to write “graphical over p coordinate “ (no two different q’s have the same p=(Df at q)).
English
@lucaslugao @francoisfleuret (Because there is no first homology.) This defines an f* on L. Moreover the fact that f is convex means that the lagrangian is graphical over the q coordinate. So f* can be viewed as a function on projection of L to that dual space. That is your Legendre transform.
English
What is something in math that you find confusing while you feel it should be simple?
English
@lucaslugao @francoisfleuret All the usual formulas follow from this. Also the favt that it squares to identity is obvious.
English
@lucaslugao @francoisfleuret The natural setting for those is symplectic geometry. A function defines an exact Lagrangian submanifold in cotangent space of the domain. If the donain is R^n, switching the 1-form the tautological one (pdq) to -qdp the Lagrangian stays exact.

@klayzerd @DrEmmaZang See we are improving your world model! Highly beneficial use of everyone’s time, I’m sure.

@MMM4699201609 @DrEmmaZang You are so stupid I am surprised you can breathe without assistance.

It’s been surprising (and honestly a bit fun) to see how much interest this little math question generated on X. Since I’m not great at expressing thoughts in short posts, I wanted to write down one last clarification and then step back from the conversation. Among all the simulations people shared, this one (x.com/chlorophilosof…) is the clearest and most aligned with the underlying math (thank you to the person who ran it so thoughtfully). It captures the key point much better than my original quick explanation did. I also want to gently note: I’m not here to compete with anyone. I’m not interested in status games or in conversations rooted in arrogance. Those dynamics don’t help anyone understand the math better, and they only distract from what should be a simple, interesting problem. This will be my final comment on the topic. Thanks to everyone who engaged in good faith and contributed helpful insights.
English
@klayzerd @DrEmmaZang That only matters on tests, and then only if you can’t talk to the test setter. Anywhere else other things matter more.
English
@MMM4699201609 @DrEmmaZang Are you stupid? The question is FROM this book lmfao. The interpretation of the question by the AUTHOR of the question is what matters. There is no death of the author in test questions.

I have terrible intuition for these problems
I'm not a real probabilist
more like an analyst masquerading as one

yep definitely captures the spirit
English
@ElliotGlazer That sometimes (often?) means “it’s more complicated than that, so different people map it to different things (“norm is good” or “norm is bad”), or refuse to equate what’s going on with the oversimplified version (“doesn’t exist”)”.
English
Looks like I got a healthy mix of "the norm is good," "the norm is bad," and "the norm doesn't exist." Successful thread.

There's a strange norm in math courses that a proof must get full marks if it's correct, no matter how unclear the writing is. In an English course, you don't get full marks on an essay just for having proper grammar, so why is that effectively the standard in math classes?
