One somewhat ironic fact of this story is that the rogue former employee perhaps deserves some credit for bringing this thing out into the world.

They had been working on this for quite a long time themselves, rightfully so. But now the whole world is working on it and exploring other methods and combinations of materials I would assume (to improve upon the original design and avoid any patents).

How long would they have kept this thing to themselves without the rogue employee bringing this thing to light?

Perhaps that was part of the rogue former employee's motivation in "going rogue": this thing needs to see the light of day so it can start to benefit humanity.

Re:Successful room temperature ambient-pressure magnetic lev... by jjallen on Friday August 04, 2023 @03:36AM (#36996698)
A former employee was the first to publish a paper with only three authors. I am surprised you haven't heard about this.

Then a few hours later a paper was published with six authors (without one of the original three authors), ostensibly by the core team that has been working on this.

There should be much more detail on the Internet if you search for it.

It's one of the reasons people were thinking this might not be a fraud.

Nobel prizes are capped to 3 people, and the speculation is that the rogue person published early to try and ensure they were one of the people that received it. No reason for infighting like that if you know it's a hoax.

There was plenty of bitter infighting over credit during the 1989 cold fusion fiasco.

Knowing it's not a hoax does not mean it is true.

As always, only reproduction attempts matter.

Re:Successful room temperature ambient-pressure magnetic lev... by acters on Friday August 04, 2023 @04:13AM (#36996967)
earlier in the week, someone posted that the person who posted the paper early is someone who wanted to fund the project, but the researchers didn't want to include him. So he took as much data as he could collect and posted it publicly with the addition of his name. He is not a researcher or scientist for the team.

In the early 90s, Prof. Choi theorized a new way of creating a room temperature superconductor but it wasn't really accepted by the mainstream. Supposedly, in 1999, two researchers in Choi's lab, Lee and Kim (hence LK), created the first sample of LK-99. They weren't able to reliably replicate nor were they able to fully explain the theory. In 2017, as a dying wish, Choi asked Lee and Kim to continue on with the LK-99 research but asked to not publish it until they understand the theory behind it. They founded a lab and collaborated with other scientists in the field and Kwon was one of them. 4 months ago, Kwon left the lab and two weeks ago Kwon leaked the paper. The paper Kwon leaked only listed Lee, Kim and Kwon as the authors and excluded other collaborators. Some suspect Kwon excluded the other collaborators because Nobel prize can only be awarded to three people at most. A few days after the leak, Lee & Kim hastily published a paper with four more authors but not Kwon.

Exactly, the 99 stands for 1999, so potentially this material has existed for over 20 years and we could have started testing and replication on a much wider scale a decade ago. What benefit have we gained by disseminating this research so slowly?
Re:Successful room temperature ambient-pressure magnetic lev... by ssl232 on Friday August 04, 2023 @04:20AM (#36997022)
I don't know if this is true or not, but I read something suggesting they produced it in 1999 as a side product of something else but didn't start to examine its properties properly until a handful of years ago.
Re:Successful room temperature ambient-pressure magnetic lev... by marmakoide on Friday August 04, 2023 @04:44AM (#36997211)
It might be that the process to make LK99, produces a fraction of the Good Stuff, which went under the radar until recently. It would not have been the first time. If it is confirmed with the proper methodology ... right now it's too early to build castles on LK99.

I didn't read a lot of Asimov, but one thing that I noticed is that he likes repeating themes like that on several books.

It could be the main theme in one, and then just a short thing in many others; or the main theme in a few.

It's less visible, but at this scale there's a high cost in everyone pausing their research to replicate LK-99. If it turns out to be real that's worth, but if not it could've gone to better use. Think of what we could've done with the time we spent reproducing cold fusion.

It's survivorship bias; yes, you would love to see the significant discoveries happen sooner, but if they were rushed you'd also see a lot of trash that currently never leaves the draft stage. Just look at how many people complained that the LK-99 papers were incomplete and unprofessional!

Also, LK-99 was discovered in 1999 but wasn't known as a room-temperature superconductor then. There are too many things to research and not enough researchers, so it was put on hold for two decades.

This is a (I feel rudimentarily obvious) fallacy of finite time implying there is N researchers working on one thing that must be useful at any given time. The individuals reproducing cold fusion / LK-99 / whichever might not have been spending their energy / time / funding on anything more "guaranteed productive" (nor even on anything at all) otherwise.

Knowledge motivates research. That motivating is not a classsically scarce resource, its multiplicative.

Seems extremely unlikely there's a "high cost" because it's already clear there's some strange properties involved in LK99. Cracking the explanation for this could potentially help advance material science in all sorts of ways.

In some ways this is pure science. Multiple groups working on the same thing increases the chance of searching the problem space thoroughly, and not missing out on finding better local maximas.

Less visible? More like invisible if you ask me. There's all sorts of seemingly frivolous research going on at any given moment. A red herring in this case would be no different.

The instant strange behavior becomes apparent it becomes worth researching. I don't see how keeping it silent is anything other than a tragic waste.

If it's bogus, we discover that sooner.

If it's legitimate, we discover that sooner, AND the benefits to humanity can begin 24 years earlier. Think of how much we've accomplished in the last 24 years. Now think of how many benefits could have been reaped during that time by building on this new knowledge (assuming it has practical applications).

If it's truly useful and they knew this 24 years ago: what a waste.

I'm sorry but this is BS (and I don't mean that as a personal attack, just a repulsion to the idea)

As if researcher must drop everything they're doing and attempt to reproduce every wild claim. It simply doesn't happen because these people are able to work through hypotheticals and form value predictions... Just like they do with any other research resource allocation decision.

No, it's far worse to lock up knowledge behind academic institutional norms and hide and yell "rigor" when anyone is curious to see what's being worked on. People can decide for themselves what is worth pursuing and the OP is likely correct that we're doing damage to our own progress by not disseminating a hypothesis that's being worked on but could use more resources. Furthermore this fear of someone publishing before you in a race to claim the Nobel prize likely doesn't help.

The institutions should formalize and normalize a method for broad open access to research in progress and broader collaboration.

The people deciding to pause their research are experts with their own agency. If they are pausing their own research then it's because they've made an expert determination that it's worth doing so. So you don't need to worry yourself over it. Open the information up so that other experts can decide what to do with it.

I'd like to add that if this claim of having replicated the material with the reportedly poor description of how to do so is true then it really isn't that hard to replicate. I am surprised they haven't published a paper by now.

And this suggests that they were conflicted for some reason about publishing, likely commercially so (as evidenced about the patent). Maybe they were trying to create a product with it that they could sell before others could replicate the material.

So the rogue employee does absolutely deserve credit for bringing this thing into the world and humanity should not stigmatize them for doing so; perhaps we should do exactly the opposite.

I have read that the description is pretty extensive, just the yelds are really bad because the production method is 1) hard and 2) inconsistent?

There's 3 main parties to LK99.

L&K, are two PHDs taught by their now dead former professor. Their research into LK-99 is inherited from their former professor but they lacked funding, hence it was a hobby project for a long time, and they needed funding to work on it full time.

The Korean professor: A professor who started taking interest and sponsoring the project for the last few years. However, he likely didn't participate directly in the research much.

The American professor (Ethnically Korean): A professor who was brought in rather recently (Maybe last 1-2 years?), to help bring credibility to the team. He is probably the one with the expertise to perform measurement and ascertain that it is a superconductor.

The Korean professor got kicked out from the team for unknown reasons. This was evidenced in the April paper published in Korea, which lacked the Korean professor's name. Quantum center also removed him from the website.

4 months later, he was back with a vengeance, and published the paper, with only him, and L&K on it (ie, the 3 man paper). The Korean professor possesses no sample, and also lacks the original data for LK-99.

A day later, the american professor hastily rushed out another paper (The 6-man paper), with L&K, himself, and 3 irrelevant lab assistants.

Since the earlier Korean paper in April got 0 attention and was treated like a typical troll paper. They probably assumed posting on arxiv was just good material for later legal battles, but they could otherwise continue happily researching and patenting their material. However, interest in LK-99 exploded like a nuke, because the first signal for credibility: That two professors were in a bitter battle over authorship, did not escape people's eyes.

2 days later, the Korean professor had a presentation at a Korean conference, but attendees were disappointed by his data and lack of samples (Prediction markets hit a low of 15% at this point).

However, the American professor took control of media communications, and quickly dissociated with the Korean professor, yet he completely stood by the claims of LK-99. Now the American professor has talked to numerous Korean media and directly sent an exclusive video to NYT.

Its interesting why L&K chose the American professor over the Korean one. Needless to say, if this works out, the interpersonal saga will end up in a Netflix documentary, and probably many court cases.

I should also note that the nobel prize is likely a secondary concern for the group. They aren't in a comfortable academic position where money is only a bonus. They were struggling PHDs for a long time. Nobel prize money is too little, and will come way too late to make a difference for their lives. L&K and the American professor are likely trying to maximize the value of their patents and know how to sell to investors, rather than to make public verification ASAP, which would be optimizing for a nobel prize.

It is not a contradiction. One can be both.

The alegation is that the person in question worked with them on the research, and they published it on arxiv without the permission of the others. Thus they can be a co-discoverer and also rogue former employee.

Supposedly he worked there until four months ago. I am just repeating stuff I read on the Internet and I don't know that we know all of the facts just yet FYI.

Young-Wan Kwon's legacy will undoubtedly be that of the hero of LK99. There is a lingering thought that had this discovery been made in the US, it might have been hidden indefinitely by the military-industrial complex, never to see the light of day.

They can still recover from this reputationally very easily assuming egos are not in the way.

Accept it happened and make amends and make those things very public and move forward to making an official announcement together with the so called 'rogue' author (in my opinion he did the world a favour).

Re:Successful room temperature ambient-pressure magnetic lev... by DoctorOetker on Friday August 04, 2023 @05:40AM (#36997628)
A funny theory, especially since this good samaritan only prematurely published after his connection to the research was severed.

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.

It seems to me they were just in the process of constructing a convincing paper, which included convincing tests and could have been acompanied by sending out samples to independent labs. Then they were essentially forced to put out what they had, which made their claims even more unconvincing.

Re:Successful room temperature ambient-pressure magnetic lev... by jjallen on Friday August 04, 2023 @07:38AM (#36998523)
Evidently they did have sufficient evidence. With such a big potential payout of such a world changing material, others have invested a few days of time into verifying their rushed paper and indeed their weak evidence was enough.

Again, with a payout so big and ease of replication fairly low, the evidence doesn’t even have to be that convincing.

Re:Successful room temperature ambient-pressure magnetic lev... by reacharavindh on Friday August 04, 2023 @07:59AM (#36998734)
An argument probably could be made for normal run of the mill improvements and confirmations that make the scientific state of the art move inch-by-inch versus such ground breaking discoveries that has the potential to help the world to such a big degree. They could very well write their finding in a way that we claim we discovered that this works, these features work, but we suspect these may also work, and XYZ needs to be tested further and those are reserved for future work either they themselves are doing are can be sped up by others participating. They still get the claim as the pioneers for the discovery(rightly so), and still accelerate the rate of practicality.

The only problem would be if they worded it in a sensational way without evidence to backup their claims like almost all battery tech seems to be these days "we discovered a solid state battery that will change the world, make EVs, flying planes, ships, trucks and remote control toys orders of magnitude cheaper, faster, safer blah blah ** once we figure out how to get it working in real world conditions and test it for real. We were talking about possibilities extrapolated from our little theoretical progress."

I still believe the scientific community is smart and moral to accept statements held true by evidence. Scoffs are reserved for hyperbolic claims.

To make my argument, see the recent paper on achieving energy positive nuclear fusion - the authors didnt wait until they could achieve Nett energy positive condition (where total energy to the system is lower than what was produced). They published when they achieved energy to the reaction < energy output from the reaction which was a big deal in itself eventhough the practical goal would be achieved in future by building upon this..

It's also worth mentioning that room temperature superconductor "discoveries" happen a lot, and have always turned out to be a disappointment.

It's been considered to be within the same bermuda triangle of scientific vaporware that demarked by quantum computers performing useful tasks, fusion power generation, that sort of thing. Always just around the corner. It's basically a meme in physics.

Room temperature superconductivity is not demonstrably impossible like a perpetual motion machine, but mainstream press picking up on yet another set of amazing claims in this field tends to (deservedly) lead to a lot of eye rolling.

The consequence is that if you've actually made actual progress in the field, you'd better be very sure you are right and able to back it up.

Re:Successful room temperature ambient-pressure magnetic lev... by pmoriarty on Friday August 04, 2023 @10:31AM (#37000606)
So how sure are we that this isn't yet another in a long line of disappointments?

What’s the track record of open prediction markets (no barrier to join) vs super predictor markets (have some requirements - be it credentials, proven expertise, or track records)?

I keep seeing markets like this posted for LK99 and personally find it unconvincing more than a sentiment analysis of the twitter and news hype cycle.

Re:Successful room temperature ambient-pressure magnetic lev... by collective-intl on Friday August 04, 2023 @11:14AM (#37001152)
The track record is pretty good, even including a bunch of small markets with few traders: https://manifold.markets/calibration

We're not, and don't think there's a physicist in the world who wouldn't advice tempering expectations at this point. Yes it would be exciting if it's the real deal, but it's also far from the first candidate we've seen and so far they've never been replicated.
Re:Successful room temperature ambient-pressure magnetic lev... by eastbound on Saturday August 05, 2023 @03:52AM (#37009943)
Talking about fusion, isn’t the major part of the Tokamak plant in Cadarache in France, dedicated to cooling down the superconductors to zero temperatures?

If we make a leap in room-temperature superconductors, do we also make a leap in fusion?

Re:Successful room temperature ambient-pressure magnetic lev... by marginalia_nu on Saturday August 05, 2023 @09:04AM (#37011625)
It would help with one (out of many) problems in that field, sure. Though it would likely depend quite a bit on the nature of the superconductors we're able to produce.

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 it wasn't revealed earlier, so that progress and applications could occur?

Re:Successful room temperature ambient-pressure magnetic lev... by shepardrtc on Friday August 04, 2023 @09:48AM (#36999988)
I can't wait to read the history of this material. 24 years... I can only imagine the conversations and drama surrounding it.
Re:Successful room temperature ambient-pressure magnetic lev... by fwipsy on Friday August 04, 2023 @10:52AM (#37000860)
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 only we knew where to look.

But surely not many of them involve a recipe we know about but have chosen to keep secret from everyone else.

Thanks for the link. Assuming it's accurate it sounds like the 24-year delay was just a bit of misfortune.
Re:Successful room temperature ambient-pressure magnetic lev... by fennecfoxy on Monday August 07, 2023 @04:49AM (#37031974)
I agree, the world still doesn't really care about science. And yet everyone's living lives that are all the more better because of science.

It's a human problem, we only care about what happens to us or our tribe and most of our focus is not very forward looking. We're better than other animals as evolution favoured us looking just a little more forward than other animals, but now we have to escape the timekeeping of our meaty flesh and think "if we dump money into science then this generation will get some cool stuff and the next will get a shit tonne of cool stuff".

Re:Successful room temperature ambient-pressure magnetic lev... by BiteCode_dev on Friday August 04, 2023 @07:26AM (#36998426)
We will never know, but maybe they receive some governmental pressure to never publish and pretend the research lead nowhere so that their country only gets the benefit.

But the rogue scientist wanted to share it with the entire world.

It would make for a nice movie.

Re:Successful room temperature ambient-pressure magnetic lev... by numbsafari on Friday August 04, 2023 @09:00AM (#36999356)
One, slightly more cynical, theory is that the rogue employee's motivation was to push the research out there in order to create an opportunity for them to engage in their own research or get funding to do that research by making public what they may otherwise have not be authorized to make public. It'll be interesting to see if there are any threats over an NDA or trade secret violations that come out of the original, premature, publication.

Everyone's assuming it's about the Nobel, but it is much more likely it's about far more lucrative goals.

Re:Successful room temperature ambient-pressure magnetic lev... by toolz on Friday August 04, 2023 @09:10AM (#36999488)
I think an interesting outlook on these situations is that if you believe someone has the right values (e.g. earning money and earning respect from peers) then greed towards those values is a nobel pursuit.

If society can't make greed go away then maybe it's better to celebrate human nature and contextualize/guide it into being pro-social.

No, they are not. The only consequence of that action was a worldwide mess of people trying to reproduce the experiment or disavow it. Original authors needed a bit more time to polish their discovery, write solid paper with undeniable proofs and maybe even prepare handout samples.
