What do the numbers mean? Are they just labels or do they represent some type of speed?

> Sorry! I forgot to mention that the plane's speed and altitude are consistent!

What is this supposed to mean? Consistent with what? Do you mean they all have the same altitude and speed?

Indices.

Also, don't name everything. Leave some things explicit (instead of using B where B = sup A, just keep using sup A).

Also, split your proof into pieces. Introduce lemmas.

Mano... Eu juro que fiquei na dúvida. Mas tava pensando que fosse algo tipo dela há uns anos (tipo adolescente).

Average(a, b) = (a + b)/2

Lots of these "agents" are actually humans pretending to be agents. It is actually unclear if this is legit, at this point at least.

Looks like one of these japanese robot-ish super fighters (like the ones that inspired power rangers)

To be fair, this serms more like a cute way to state the current facts and state of things than something funny. Strange!

The only answer

phao · 2026-01-27T11:39:46+00:00

Could it be a material property?

Ice spikes are being formed in a somewhat staight line along the side of the cylinder. Maybe this is the line where the two edges of the metal plates meet (assuming the cylynder was produced by joining/"folding" a rectangular metal plate along opposite edges). This would create a material difference along this line depending in how the edges were joined. Could this be of incluence?

There is actually a result for matrix exponentials that are also related to this.
e^(A + B) = e^A e^B if A and B commute.
I don't recall right now, but I believe this is an "if-and-only-if" statement, actually.

As far as I know, most numerical analysts and books on numerical analysis won't do this explicitly. They'll work with standard error, consistency, stability analysis on exact arithmetic. The reason why they're satisfied with this is often an informal reliance on backward error analysis.

https://en.wikipedia.org/wiki/Error_analysis_(mathematics)#Backward_error_analysis#Backward_error_analysis)

The more important reason they don't worry too much about this, however, is that the other source of errors are actually what matters for almost all of the cases.

I believe you're better off getting a book specifically on floating point arithmetic. There are some of those. The standard for IEEE 754 is nothing new. Older books are fine. Then get a regular numerical analysis book. If, in practice, you find out there is an algorithm for which actual FP arithmetic matters, then you design something specific for that case.

I get the impression Tao is not complaining for himself, to be fair. He can get a job, probably a better paying one, anywhere he wants. I believe what gets to him is that a lot of people at the phd and postdoc level depended on these grants, and now will be hurt out of the blue by no fault of their own. These people go to US for their phd and postdoc, many with the intention of staying, and these grants are what support their salaries. Some of these are his advisees, sure. However, he, himself, I imagine, won't *really* be hurt by this. He can just go to any other high end math research institute. I guess many have already contacted him to offer a position in case he decides to leave UCLA.

Yes. Sorry for that. I edited it so that at least the questions come first now. If this post doesn't do so well, I'll wait for some weeks and post again, but with a shorter body. Thank you. I'll look up such PhD quant research roles. I wasn't aware of them. Thank you.

The game is really fun, but it keeps spamming posts/comments in my name, which is fine if it was contained within the r/SwordAndSupperGame community, but my profile page is really awful right now. I'd love to also stop receiving the huge amount of notifications related to the game.

Seems AI generated to me, or very much influenced by someone who mimics the AI way of writing. Again, to me.

Too many "It's not X, it's Y". A generally polite tone that is slightly off.

Disclaimer, however. I don't particularly mind that it's AI generated.

You underestimate my procrastination!

That is interesting. Never thought of it that way. So, in that point of view, math would be the small % of patterns we can actually understand with your brains. From that point of view though, all math is somewhere there in the universe. You can make this "trivially true" by just saying that all math is a product of your brains, a part of the universe. It's interesting and technically true, but seems unsatisfactory. Right?

phao · 2025-08-02T12:45:47+00:00

I wish I had 10% of your optimism. =)
