When time allows. Quite a few remaining folks play.

I'm not sure about that 3500BC, but it was certainly widely known and treasured. Here's a fun quote:

Pisthetærus

Hand me the cheese-grater; bring me the silphium for sauce; pass me the cheese and watch the coals.

Heracles

Mortal! we who greet you are three gods.

Pisthetærus

Wait a bit till I have prepared my silphium pickle.

From Birds by Aristophanes

You know, I'm not a fan of chess.com overall (sorry weewoo), from putting everything behind a paywall to fugly interface, but it's undeniable their cheat detection procedures are the state of the art. And Carlsen's gut-feeling it out can just be bias, but equal opponent not looking pensive enough tipped folks even in my small-potatoes club, and it was rarely unsubstantiated later. It may read like a gossip, but barring some solid evidence to the contrary, it looks pretty clear.

Which is why there's the need for more measurements of possible coinciding variables. Changes to pressure, electrical and magnetic fields, LIDAR, doppler and about a hundred other things can be checked or cross-referenced.

Also:

    Seems like anything flying that fast couldn't be matter as we know it.

    I think there's a bias because of the explanation of them being spacecraft.

I would have been so on board with the latter quote if you bothered to start with it instead of the usual.

I guessed and failed from Polish "Czelabińsk," forgetting we usually simplify Russian "lj" sound to just "l" mid-word.

Chelabynsk meteor was faster, tho.

No, but really, unless it's some unheatable adamantine-grumril alloy with active Freedom of Movement, among other things, you should detect a corresponding change in pressure. If their numbers are correct, it's an easy measurement, too.

    Phantoms are observed in the troposphere at distances up to 10 - 12 km. We estimate their size from 3 to 12 meters and speeds up to 15 km/s.

    15 km/s.

That's 54000 km/hr.

That's almost Mach 44.

If it was there, you'd hear it.

    When I grew up there was one form of deprecatory humor that was safe, no matter what: Polack jokes. [...] Persecuted Eastern European minorities? Might as well pick on the Martians.

In 2003-ish, there was a pretty big market for cheaply printed joke books in Poland, and one month they printed Black jokes. Someone objected to it as offensive, so they reprinted a find-and-replace version with same material, but this time about Blue people. I guess it's both the proof and a show of just how lazy comedy can be.

I understood it as c_hawk refusing bulk grunt/admin work for everyone in lab/team, especially one that should be done by persons for transparency. And kudos for that.

It certainly takes prompts into account.

In the pizza box model, the inner door opens with vacuum on both sides, while the outer one would have to open inward with the help of inflowing air or outward against the atmospheric pressure and inflowing air. We can do better.

    I probably need Devac to vet and/or refute the first paragraph, especially. If he wants to, of course.

I'm gonna level with you here: this is far out my zone. Currently reading through this article and sources/followups to get more up to speed, but doubt you'll get much from me. The topic itself is kinda like solving Riemann's conjecture -- I obviously tried, but don't really have an opinion or profound (for a mathematician, at least) grasp of implications?

As far as I see it, the real problem is that, as with Bohmian mechanics and many similar hidden-variable theories, we can absolutely postulate it as valid but decisively testable only under the assumption we can achieve an infinitely-precise time resolution of the measurement... which we obviously can't do so the topic itself is moot at best, faff at worst. Especially in a world with better, more general and easier-to-use theories.

    And yeah, if I didn’t have a physics background, I'm not sure how much I would get out of the PBS Space Time channel.

Dunno, but it introduces you to related vocab and concepts (or even points to a discipline, which is not always a trivial thing to determine), often accompanied with some intuitive animation/diagram, which alone honesty kicks the everloving shit out of many popsci books, picture being worth a thousand words and all that.

Clever. I just thought about pestering him via email and social media, like common rube.

But you just had to interact and collapse the thing, didn't you?
