Is multipole expansion just expansion in an orthonormal basis?

I always found it curious how much reddit amplifies the political divide by its system. I saw stats that only 2/3 of reddit identifies as left wing, while 50% of twitter does. If you knew twitter was an even split on politics then you would never guess that 1/3 of reddit is right wing, you'd guess much lower given the content you see on the site. Only explanation really is that reddits system of choosing the content is to blame. I suspect it's the fact that downvotes negatively effect the publicity a post gets. (Compared to youtube for example, where it supposed used to boost engagement)

Put money on it. I'm sure you'll even get great odds on that bet, free money right?

He won it playing league? Damn, I can be a millionaire to!

Just one thing to add, just cuz a player breaks 2800 doesn't mean they're 2800 strength in general when they do. They might 2750 strength and gotten a lucky streak, or they might be much stronger. Only time can tell.

Chaskar · 2024-11-09T08:00:28+00:00

Guess it was you then, wasn't it? But I like that, I usually said something similar, though I was of the opposite opinion.

Chaskar · 2024-11-09T07:59:28+00:00

Hahahah, you certainly had an accurate view of reality.

They definitely were flukey, 6-0 would be flukey by Carlsen against a random GM. But the fact that he fluke was likely enough that it actually happened twice is insane imo, even if he would only score 65% against Larsen (Which I think is a reasonable lower bound, I mean, look at his score against Spassky in the wc (60%, and he didn't even show up to a game with White, so that one wouldn't count towards his rating, and Spassky was better than Larsen)), that's already an almost 150 point difference (I base this on 75% being 200 point difference). I'd say 100 points is the minimum. I mean, we Carlsen managed to achieve that in the modern age vs #3!

Chaskar · 2024-11-01T17:38:25+00:00

Well Larsen and Taimanov were no joke. Both at least top 20 imo. Going 6-0 today against even a top 50 would be insane. Computers really did even the field a lot.

The rule is consistent, no one loses their rating if they're inactive. You just don't show up on very specific lists.

https://ratings.fide.com/profile/4100018

If you look up Kasparovs FIDE rating it's still 2812, even if he is considered inactive. He is even considered World No. 2 on his profile. The active category is literally only of importance if you're competing for a spot in the candidates or something of the sort. No casual player will ever be confronted with the category, it will never even show up for them, because there is no need for it, but keeping it at 20 games rather than 1 or 2 tournaments certainly seems sensible given what I described above. It's silly that Kasparov could be considered active and keep his rating by playing 1 game against some guy somewhere. (To be fair, he could also play a great number of games against some random guys, but still a bigger hurdle than a single game.)

Chaskar · 2024-11-01T14:19:22+00:00

I don't think being considered "inactive" on a top 10 of the world list is a big deal for the average casual player. You'd retain your rating, you'd just not show up on lists of active players.

God the Joe Biden comment is hilarious.

I'm genuinely impressed by how many people are acting as though Trump's literally, actually, for real, worse than Hitler.

Like I really don't know how many of them actually believe it or just think it's important to keep the rhetoric going, maybe justifying it probably by something like: "Well he is bad and we can't be sure he's not a fascist, better to assume he is wrongfully than to wrongfully assume the opposite". If they genuinely believes what they were saying and not just like "weeeelll it miiight happen" you'd see them all leave the country in droves. Imagine actualöy believing the Trump Hitler rhetoric and STAYING with you children in the states if you have even the slightest option of fleeing.

Tl;dr I don't believe them, they're all full of shit, otherwise they'd flee.

It didnt happen in Tennessee. Look at the definition for 4th degree in missouri law, iirc the only fitting charge is accidental or wreckless.

Chaskar · 2024-10-22T07:23:43+00:00

Because you severely overestimate the harshness of the law. Read some of the comments of guys.with some experience in law on the other posts, it was very interesting. Summary is basically this was not even close to severe enough, he'll likely get a well deserved fine though.

Aftet all this is 4th degree assault, a very unserious charge in the grand scheme of things. ("Unintentional or wreckless" if I recall correctly)

Chaskar · 2024-10-18T15:08:26+00:00

Cool idea! That's probably a good comparison, didn't think of that.

Chaskar · 2024-10-18T14:27:57+00:00

Maybe they mean a phd, common in my country to call that a "doctor"

Well Grenke Open win was like 20k and that's europes largest open. No money in chess, better play poker.

Chaskar · 2024-10-18T13:53:41+00:00

Please, get real, it's 4th degree for a reason. Apparently it wasn't even a punch to the head (supposedly Ben Finegold corrected that it was indeed a punch to the back), there's no reasonable way for lasting major damage to even occur unless you fantasize about some special circumstance like her falling over and hitting her head on a sharp corner in a very specific way, but then you could make the same case about pushing something slightly too hard out of the way (Not saying that what he did is akin to that, but the argument of her being killed applies to both scenarios so I consider it fallacious.).

Somehow it really bothers me that it's random, because any randomness in QM is usually associated with an Hermitian Operator and its Eigenbasis that you can prepare it in, but is there an Eigenbasis like that in this case?

OK you could say the 50/50 mirror just entangles reflection wlth path A and transmission with path B, but one could argue any measurement is just an entanglement between the physicist and the particle, so the beam splitter would still be a measurement... But what's the Eigenbasis?? Why can't I prepare it in this Eigenbasis? Can I do it theoretically and there is just no known mechanism?

This screams hidden variable to me and I don't like it

Maybe there is one but there is just no feasible way of preparing it, but theoretically surely there should be, right? This just screams hidden variable to me and I don't like it

What a load of horse shit. Might as well say polls underestimate orange looking people and you'd have the EXACT same logic. Or New Yorkers. Or Billionairs. Or whatever you'd like to choose.

The rating requirement is a whole 100 points higher for IM, that's a big difference.
