LK-99 isn’t a superconductor

Re: LK-99 isn’t a superconductor
#322You can publish an article with a title like this and probably not end up embarrassed. Room temperature and pressure super conductors seem hard enough to find that chances are any given paper claiming to have found one will end up with a more mundane explanation. And I do think the information about the phase change of Cu2S is highly relevant, as it points at a way the original researches my have fooled themselves. T…
>so something in those samples the original team recorded must be extremely diamagnetic to make up for it!
I wonder what would have happened if they would have pushed a paper out talking about anomalously high diamagnetism and skipped any mentions of superconducting. And let people speculate if it is a superconductor. I suppose we wouldn't be talking about it. But I hope that we see some group try to replicate the diamagnetic material properties.

#323Company that has already lied in the past lies again, and everyone eats it up, again... The internet has taught me to never trust material science advancements at face value. Batteries, solar power, superconductors, nanomaterials.. Even when they legit work, there is usually a straight forward reason why it just isn't feasible, and that is conveniently left out of the press release. I have to go to the HN comment sec…
"Company that has already lied in the past lies again, and everyone eats it up, again" - what are you referring to?
Re: LK-99 isn’t a superconductor
#324I felt like folks were getting too optimistic in the early days and now I feel folks are getting way to pessimistic. We don't know if any of these failed replication experiments actually made the same LK-99 the Korean team did. The only way of knowing for sure if LK-99 is a room temp superconductor is if outside labs test the samples the Korean team has made. It's entirely possible that the exact impurities in their material caused by their exact manufacturing process are required for superconducting properties to emerge. Seems like that will be done in the next few weeks. Still betting against it working but keeping my fingers crossed.
Re: LK-99 isn’t a superconductor
#325While there's certainly a lot of evidence that its not a superconductor, no one can make the definitive statement that this article does without testing the original sample.
Re: LK-99 isn’t a superconductor
#326Honestly, I feel bad for the original authors, who were correctly holding out for stronger evidence but were forced into publishing early by the actions of a third party going behind their backs. I hope they don't experience undue blowback because of this.
I'm not aware of it, anything to read about the said third party?

Yeah, the power of Randlow's law cannot be understated.
yes, Steven's law has such utility
Do I read it correctly that doubling the amount of current through your fingers feels like 10x’ing it? If so… shocking.

I think the story might be more complicated than that, I remember reading that the "third party" was the one paying the bills for the experiment so pushing it out early and even publicly failing would've been preferable to getting it dragged out infinitely for an unlikely hope of it being successful.
This funder-rushed science exactly what created Doc Ock and the Green Goblin.
They both had some pretty ground breaking technology to be fair

Agreed! There's this bizarre reaction I see from many where they see the excitement and curiosity and hopefulness as a form of error and source of embarrassment. When mixed with an open mind and reasonable skepticism, it's a powerful opportunity to get people engaged in imagining a different world. I had all kinds of exciting conversations about what a validated, commercially viable LK-99 could produce. Why would I e…
> When mixed with an open mind and reasonable skepticism, it's a powerful opportunity to get people engaged in imagining a different world. I feel like this line is doing a lot of lifting in your comment. The problem is that as lay people we are completely unequipped to gauge a claim like this. I followed along on HN and there were plenty of posts by people who were giving LK-99 crazy odds of success, fueled in no sm…
What's "crazy odds of success" to you?

In this case, I think the excitement and hopefulness was not dangerous or wrong, but I do see a risk to this kind of preprint hype in other contexts. During COVID there were multiple cases like this where a study got a lot of hype and discussion from non-experts and turned into "the science says X", when in fact the science was as of yet extremely unsettled. Sure enough, as the experts came to a consensus it rarely m…
Have we been so throughly baked into anti-intellectualism that people who can read, and use that advanced skill on Wikipedia, along with the other skill of critical thinking, are to be denigrated as "armchair X-ologists"? I know our country's rallying cry is "Math is hard, let's go shopping", but not all of us have bought into that anti-science, anti-knowledge, anti-being-smart-at-all attitude. Thanks to a lot of har…
You're attacking a very elaborate straw man constructed around a single phrase in my comment. I didn't say what you think I said.
