By the way, in case you lost track of this among other news, the scientific consensus now is that "LK-99" is not a room temperature (or any other kind of) superconductor, and that the "levitation" noted was a magnetic effect caused by copper sulfide impurities. Oh well ...
@lauren But despite the outcome, this was a very nice teaching experience: In contrast to other big science claims of the past decade, this one could be tested by many labs and the public could see how science really works. So, overall, a positive! #lk99
@J12t A bit pretentious of CMTC. Is #LK99 a superconductor? Unknown. Is what CMTC synthesized, according to the scant details available in pre-publication, LK-99? Probably not. There’s no shortage of LK-99 replication attempts that have reported unusual or interesting properties.
It is interesting watching #Twitter (from afar) sheepishly backtrack on the #LK99 hype.
There were three, maybe four ringleaders as far as I could tell - which included some that are competent in science and physics that should have known better.
But whipping up useless hype gets people paid by Twitter at the moment.
It all really underscores my position on how unsuitable Twitter is for actual science and public education - and that was fairly true even in the pre-#Musk Twitter Era.
Some (perhaps even many) have now argued that the #LK99 hype was, in fact, good for science.
Sure, if the public was left with an understanding of actual scientific foundations so that, possibly, the next conversations could be more productive and informed.
A missed opportunity, if there ever was one.
But, crucially, one that us in former “System Safety Twitter” community know all too well - and there, the #Twitter hype has killed people.
Don't get me wrong, I'd love for #UFOs to be visiting aliens, for #LK99 to actually be a room temperature superconductor and for #Fusion Power to be here already, but the evidence just ain't there and hucksters are preying on our optimism.
A lot of people got excited by a report that a material called LK99 is a room-temperature superconductor. Researchers raced to validate the claim. Now the early results are out--and they don't look good.
"I expected that interest in LK-99 would just die a slow death after no one could replicate it; rarely is a smoking gun found that explains the spurious observations.
But in this case it seems we have a full coroner's report!"
To everyone freaking out about how the definitely-real 100% replicable room-temperature superconductor will fix climate change, apparently overnight: what if I told you that there’s a miraculous power source that literally converts sunlight straight to electricity? And that it’s existed for decades? And that, thanks largely to fossil fuel interests, we barely use it?

Room temperature superconductors will destroy hundreds of jobs in the magnet production field and need to be stopped until we understand the implications.
They had to pivot from Ukraine War Experts to UFo Experts to Russian Coup Experts to Women Soccer Experts to Maritime Drone Experts and now they need to become Superconductor Experts.
If the LK-99 “superconductor” is the real deal, it could be revolutionary in a number of ways. But it’s not without its share of skeptics. The Verge spoke with a handful of experts in the field to try to sort the science from the hype. https://flip.it/Z4Yw6D #Tech#Superconductor#LK99#Science
First independent verification that LK-99 does in fact display superconductivity at temperatures up to around 300ºK - room temperature. And possibly up to the boiling point of water, folks!
If this keeps up we have a genuine scientific revolution on our hands.
Look a room temperature super conductor that is patented, needs highly specialised equipment and will be owned by corporations is cool and all.
BUT it is not revolutionary like massive batteries just about anyone can build with a cement mixer and can be built into your house, path, windfarm, solar farm concrete using simple readily available materials.
We succeeded in synthesizing superconductor (Tc≥400 K, 127∘C) working at ambient pressure w. modified lead-apatite (LK-99).
LK-99 superconductivity shown w. critical temperature, zero-resistivity, critical current, critical magnetic field, Meissner effect ...
127degC is not room temp
nice if true 🤔 👍
RT ambient pressure superconductors will be revolutionary when available
