It takes a lot of cognitive dissonance to be pro USSR in the first place, so a little more shouldn't hurt.

USSR means something different to Russians than it does to Americans. To Americans it was the Enemy. To Russians it was the last time that Russia was truly important on the world stage and had some degree of prosperity.

I think it's kind of like the 1950's for white supremacists.

There is a Checz lab also documenting the process https://twitter.com/CondMatfyz

I am totally confused, it is documented in the original south korean paper, why anyone would want to rely on such second hand unverified info when first hand info from the original inventors are freely available to everyone?

That's one of the core tenets of science of course: experimental reproducibility given reasonable instructions; the laws of physics are the same everywhere in the universe, well except for possibly blackholes

Seems kind of stupid to do chemistry in your kitchen. What exactly is the rush here to come out with results right now ?!

> What exactly is the rush here to come out with results right now?! Well, the work is happening right now . You seem to want to make it sound like impatient kids being unreasonable or something, which is a ridiculous read. It is more a matter institutions becoming irrelevant because they literally can't keep up with their peers. Which brings me back to, > Seems kind of stupid to do chemistry in your kitchen. When th…

Hmm I'm not convinced that the establishment is sitting it out. Isn't it more likely that they are working the conservative process of registering experimental intent and planning only then to be followed by the experiment and only then to be followed by press release? If a bunch of amateurs can spook the old guys into violating well established procedure then id be pretty concerned about their competence.

It's just done differently, I don't know, it's hard to explain, but: A: [orders some chemicals] B: God damn I love America A: Hell of a thing, America C: greatest country in the world just reads so weirdly to me. Maybe it's partly that I can't imagine finding (or any other British/western European person finding) this a source of national pride to begin with, but even when it's something we do.. I just can't see non-…

While most of it is probably sincere, it's also important to keep in mind that some people do the "overly patriot American" as a joke.

My troll account on twitter is a mishmash of patriotic words that make no sense but I still have 8k followers lol

What would be an explanation for the partial levitation of the LK-99 sample shown in the video?

Could be normal diamagnetism, or even ferromagnetism. Very hard to say as they don't even give any field strengths in the video, it's just a Neodym magnet they hold near the sample. If I understand the video correctly they just orient the magnet by hand, so I would not even rule out a ferromagnetic effect. There can be multiple regions with different orientation in such a polycristalline material, which can produce a…

To me, this video looks like the sample is experiencing a torque, not a force. (Or at least not a force that is sizable compared to the sample’s weight.). The sample is doing a remarkable job of cavorting without actually going anywhere. Magnetic dipoles experience a torque proportional to the applied field, whereas the force is proportional [0] to the field’s gradient. The field gradient may be fairly small near the surface of a big magnet.

Plenty of things are magnetic dipoles or can be induced to become dipoles in the presence of a magnetic field. Ever played with iron filings and a magnet? Or a ferrofluid and a magnet?

[0] Assuming the dipole moment is constant.

He’s replicating a cutting edge material science in his garage. People are celebrating the optimistic spirit of Americans. The indomitable will that this country encourages and the sense that anything is possible if you’re ambitious and smart enough to pull it off.

lmao (a) it's an industrial lab. (b) if there's any optimism to be commended, it's that of the South Korean researchers who worked on this on-off for ~20 years.

(A) It’s a metal garage that has some industrial equipment in it. There’s literally a motorcycle parked in it.

(B) The Koreans will rightly get their Nobel if this pans out. But what McCalip has done could never happen in a place like, say, Europe. The people there just don’t have the fortitude (those that do come here!) for this kind of thing. America is rich with ambition and creating the future. Other places had their time and are just fossilized remains now. But fun to tour, especially when the people there dress up like their glorious ancestors that made them famous did. It’s fun to look at the past sometimes (but obviously not live in it!).

Garage? That’s an industrial lab

With a motorcycle parked in it. It’s a garage space with some lab equipment in it. This is pure modern Americana.

I don’t think the USA is at the forefront of science, and I’m really disappointed to see discoveries like this originating from South Korea, China, and Russia before we saw results here. But even in light of that, I don’t think it’s very controversial to say that the USA is inarguably the greatest country on the planet. While it's true that the USA may not always be the first to every scientific discovery, what it is…

It’s simply because the US is the richest country on the planet[0]. A lot of money buys a lot of science. Many of those great discoveries are not made by Americans, if you look around at any of those American universities you’ll see people from all corners of the world. So yes, the US is quite good at research, but it’s not due to some intrinsic quality of the country any more than a billionaire’s ability to attract…

That's my point exactly. The USA is a melting pot of all other nations. We have some of the most genius minds from around the globe, and it's exactly the fact that it's the richest nation in the world that makes it the best at many things.

I don't deny it's awesome, but this is Varda's lab (pretty well funded VC startup). They're inspirational, but quite far from a lab :)

Lots of bizarre pro-Soviet behaviour from her as well which feels somehow connected

She's _literally_ Russian, not ironically. So not so bizarre.

Well, she said, she's ethnically Ukrainian. It was great times for us during the USSR so not that's why I was finding it a bit odd.
