This is a quite biased view. As a non-Chinese scientist, I can attest that there is intense pressure to publish as many papers as possible pretty much everywhere , and this leads to a problem of bad research across the world. China may be among the worst offenders in this respect, but the particular thing the OP is asking about doesn't strike me as a Chinese-specific thing at all. I see non-Chinese scientists rushing…

It's not biased, it's a fact. I see it all the time as PC/AC/reviwer/etc. There is deluge of terrible papers from China that are just a mess, below any imaginable standard. Ones that labs in the EU/US/Russia/Japan/etc. don't put out. Yes, everyone has to publish, and there are bad papers out there, but the volume and low quality from China is unmatched.

Unmatched doesn’t make it qualitatively unique. It’s a problem everywhere.

very interesting, is there a an article about it?

not an article, but there's a tweet (yeah oftentimes Twitter can be useful :) ): https://nitter.net/sanxiyn/status/1686782919178911744

nationalism/patriotism is gross, except for the people who happened to be born in the same country/political system/religion as myself

> I think there are multiple big reasons they didn't publish sooner. It is pretty clear that they were convinced, but had insufficient evidence to convince others. Additionally there had recently been a sensational fraud in their field so journals would have been extremely sceptical. But hasn't it been 24 years since they discovered LK-99? Or am I missing something? If that's true wouldn't it be a tragic shame that i…

It was originally discovered in 1999 but was shelved for over a decade due to insufficient funding. As I understand it, they only received funding in 2018 and became more confident in their discovery after that. Here is some (speculative?) backstory: https://twitter.com/8teAPi/status/1684385895565365248 It is a tragic shame in hindsight, but no doubt there are many earth-shattering discoveries lying within reach, if…

This is obviously a quickly produced paper to get the finding out but.... I find there to be so much missing and so many things poorly worded or posed about their process that would have taken zero time to expound upon, it's infuriating. "All the reactions are carried out under 10^-2 Pa" OK, I know they mean 10^-2 of vacuum. But why not say that? "10^-2 Pa" isn't enough. Was this a full vacuum oven? Done in sealed qu…

What personal benefit does this gain someone to publish it so quickly? Is it just social media attention?

Citations. The early papers will be cited more often. And citations are kind of a currency in science.

People called the Soviet anime lesbian kitchen chemist a LARP but this is either Nobel or a fraud, personally very heavily leaning towards fraud.

Do we have russian anime lesbians doing superconductor chemistry in 2023? I'm here for it.

EDIT: This is probably fake. The account was just created and can't find any info online. Also the pellet returns to its starting position for some reason. Just saw another unconfirmed replication here: https://twitter.com/instsondaw/status/1687433935012139008?s=...

I thought for a second you were referring to the original post with the edit

I no nothing about superconductors. And have been largely ignoring this until it seemed more certain. Can someone ELI5 why this matters? What does it enable technologically? Flying cars? Fusion reactors? Magic fix for global warming?

You could run a cable from sahara to the America to send solar power in the night

The conductors of your ohmmeter are not that important, though. You can work around that by using four-terminal sensing, and you can of course also calibrate your probes by directly touching them together. Even if your ohmmeter conductors have a resistance of several ohm, you could still get an accurate measurement if your tool has a high enough resolution. A bigger issue is going to be sample size. A 1mm-diameter 1m…

How about the wires connected to your probes? Or the internal electronics that are used to gauge resistance? How do you work around those?

simply build the material into a device that cannot work without superconduction and then see whether it does ;)

A good one would be "productive AI." People forget, but a short while ago, AI was treated as something where being actually useful was perpetually 20 years away, and the real-world status of it was exemplified by a chatbot like Eliza.

When AI was 20 years away, people seemed more optimistic about it than now when its inevitable transformative societal impact is seemingly right around the corner, are you sure this is the kind of example they were going for?

Because AI is a tool of corporations. Corporations that already show a massive indifference/hostility to "customer service". Corporations that reduce you to data points, that treat regulation with open disdain (see: Uber), corporations that built perpetual private surveillance empires (and therefore the actual state has a turnkey infrastructure for total information awareness).

THESE are the companies wielding AI, but this time without nary a "do no evil" in their ethos, long expunged. They are wielding AI with dystopian surveillance and the inputs.

In the era where the Supreme Court has declared them immortal citizens with allegedly the same rights as a real human, except they can't be killed, they can't be imprisoned, they can hop jurisdictions with the filing of a document. They operate under citizens United so there are no limits to their influence on elections and politicians. They can "bribe" with speaking/speech fees. They gain tax breaks that a "real" human can't possibly imagine.

Do you trust Google, especially these days? Do you trust Microsoft, unrepentant sociopathic MBA monopolizers galore? Do you trust Amazon who reduce humans to robots, with the outright stated goal of replacing them someday and churn through human resources at rates that make the Soviet Army in WWII blush?

If a firearm is just a tool and its danger depends on the owner, who is brandishing AI-the-tool?

Uhoh.

Cold fusion all over again. All the internet predictions of what this will bring are kinda cringey and pathetic

Not even close. Cold fusion was not something we thought was possible under our understanding of physics at the time (Muon-catalyzed fusion isn't what they thought CF was and there are all sorts of things that make it not really something that we expect to ever be particularly useful for power generation, etc., so not much purpose in talking about it) Meanwhile, all our known physics have no issue with an RTAPS exist…
