AFAICT this has not yet been published in a scientific journal, and has not passed peer review of any sort. Having said that, there's been at least one story on HN this past week where researchers were chastised for going to the press before properly vetting their results.

It seems to have been published in a Korean journal: http://journal.kci.go.kr/jkcgct/archive/articleView?artiId=A...

Back in April and there's been no other cites of it since then?

Will they invite a wide range of experts to publicly test their material?

This stuff is the materials science equivalent of making a baking soda volcano, in terms of difficulty. If their results are BS we will know quite quickly. I have no doubt people are attempting to reproduce their results right now. If they wanted to get the credit for a BS discovery they definitely could have picked something harder to reproduce. They're making a very easily verifiable or falsifiable claim.

That's a good way of putting it. If you are a fraud, why make it so easy for someone to call your bluff.

Word is one of the most common tools for writing papers. There was a study a while back that looked at the quality of Word or Latex papers. The study found that researchers using Word were more effective, and the working theory that explained it was that people who focused on the research did better research, and people focusing on the typesetting do better typesetting.

Latex is a waste of human potential. I've done professional typesetting and cataloging with QuarkXPress and InDesign both and it was extremely fast, that's for professional high quality publishing. .doc and .md is fine for information first publishing. Latex is not simple and is in my opinion just a big nerd snipe, its the intrusive thought of layout software, for humanities sake we'd be better off with simpler tools…

Reminds of "command line is faster than GUI" folks who get timed doing every task slower. "But it feels faster!"

Levitation is to be expected for any superconductor when it's in a superconducting state; that part is banal. The big question is whether it's actually a superconductor at RTP. Their results are strong enough that it's unlikely to be a mistake, though fraud is possible too (although it is so easily uncovered given the simplicity of preparing the material and the strength of the reported effects that fraud seems almos…

The recipe in the paper is so simple that it's giving me Pons-Fleischmann vibes. It reads more like an entry from an alchemist's journal, reproducible with chemicals and equipment you could buy on eBay or Amazon. So, yeah: big if true.

Silicon is one of the most abundant elements on Earth and for thousands of years humans had no idea what would be possible with very controlled etching of it.

> the biggest scientific discovery of the last hundred years I would say that electronic computers would take take the first spot for me, but I don't deny that room-temperature superconductors would be pretty close to the top.

This (or something derived from it) would be used for power delivery literally everywhere in the world. It might well be bigger in scale and volume than all the computers.

While that would be nice, it's not exactly revolutionary. We can already build cables to transmit power over vast distances and can certainly imagine a world where we do the same, but with higher efficiency. The computer transformed how we live our lives and reshaped our culture, to the point where what we are doing right now - casually chatting with anonymous people spread around the globe about a scientific paper that we can all read at our leisure immediately upon publication - was inconceivable within living memory.

After skimming the paper, it reads like a legitimate paper even though I have zero expertise in the area. That it is in Word instead of LaTeX makes it feel a bit less legitimate to me and they could of course always have some error in there setup. The most notable thing to me was that this was done in a thin film where structural defects are supposedly responsible for strain in the material which in turn enables the…

Ironically, the paper itself was republished to fix figure placement [1].

To your main point, no, theoretical physics paper are almost all written in latex. I can't recall word-written theory paper. Experimental papers are sometimes word, but pretty rarely. You can try randomly sample papers from cond-mat arxiv to verify it.

A sister paper [0] has a photo of the material exhibiting the Meisner effect and levitating over a magnet, and claims to have a video too. Either they blatantly photoshopped the photo or they actually made a room temperature super conductor. I can’t see how the could have made a subtle mistake that resulted in magnetic levitation at room temp without making a superconductor. [0] - https://arxiv.org/abs/2307.12037

I really need someone to bring me down a notch. This is too exciting!

Dunno. A fancy tape or such made out of lead compounds would be a hard sell in comparison to ordinary copper for household wiring. But yes, for serious uses, this will be a big deal if it works out and can be made into a flexible cable. And I’m sure people will work on a less-toxic version.

I think we'd get over the whole RoHS thing, if room-temperature superconductivity is part of the deal.
