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…

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?

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.

This reminds me of an Asimov novel (don't remember the name)

In this universe there are long life humans that don't really collaborate with other humans (like a single person, not a group of quasi immortal humans) in the scientific field to have all the credit because who cares if you take 200 years for a discovery if the glory is all yours

> 6. World recognition to manage resources globally Do you mean communism?

- Protect the Amazon - Distribute food instead of wasting it - Build more trains, turn roads into park ways and bike paths - Recognize climate change globally before it kills us all

The earth's climate changes naturally over the course of tens of thousands of years. The key for us is to minimally impact it and let it do what it wants.

Now.... We may disagree on letting it go as it goes. Ice ages would overtake a ton of countries in glaciers entirely, so we may agree that that should be stopped? But........ Doing that would be directly trying to challenge the solar system and earth on their natural cycles. There would likely be massive unforeseen repercussions.

> Danijel Djurek, a physicist at A. Volta Applied Ceramics in Zagreb, Croatia, claims that he discovered his superconducting ceramic mixture in the late 1980s. But he was unable to pin down the structure and formula of the material, and his research was interrupted by years of war, following Croatia's split from Yugoslavia.

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 t…

>reportedly poor description of how to do so

Isn't it false?

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?

So the description is good but hard to replicate

It’s a breath of fresh air reading about actual revolutionary science happening. The deluge of news about non-replicable results, fabricated data, overhyped press releases from both academia and industry had become really depressing. For once after a long time it’s the real deal. Even if this is not a RT superconductor, it’s now evident that the original authors didn’t cheat and are not crackpots as initially suspect…

You know, most of that stuff you hear about are bad takes on science. Science has moved into the realm of trying to understand complex systems with a lot of noise and with unknown variables. There will be a lot of misses; but that is how sausage gets made.

Well steady on there. The problem people have with bad science is not that there are misses, it's that there's no way for them to reliable decide when they've had a hit and so they end up inventing fraudulent pseudo-science. What's happening with LK-99 is science as people tend to imagine it working. Hypothesis -> experimentation -> replication -> theory.

But that sort of science seems to be quite rare. Most science people are exposed in their daily lives is of the Francesca Gino variety, and that's not merely "a lot of noise with unknown variables", that's "nobody will care if we don't do real science so let's not bother".

Wait, how did co-discoverer a few days ago become rogue former employee today?

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 p…

This is a fantastic rundown of some very confusing events, thank you.

I also hadn't heard about this for what it's worth.

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.

I even wondered about that, is ever a thing?

Like saying "SORRY, FIRST" to the nobel committee?
