#2Thoroughly upvoted and discussed "The first room-temperature ambient-pressure superconductor?" https://news.ycombinator.com/item?id=36864624
has barely fallen to second page yet, but as the topic is of exceptional interest, and under development, and Lowe's commentary is usually welcome and well received on HN, maybe some duplication can be justified in this case?

#3One odd thing that I've not seen any discussion on: the reported heat capacity of LK-99 decreases above 250K, which is pretty atypical. Has there been any commentary on that?

#4Lots of people are saying there should be a quick turnaround time here for trying the replication. I wonder how much it would cost to try and replicate this, in materials, labor costs, and vacuum furnace time/costs. My naive thought is that that labs in general aren't just going to drop everything to try an replicate every instance of someone declaring they've discovered room temperature superconductivity. Seems more like a "there's a lull in paying work, so hey, why don't some of you junior technicians try this out" thing? Anyone have insight into this? I suppose a university lab might have more leeway here to try out spur of the moment experiments? Maybe this is a "I'm personally interested in this and I'll work in the evenings to test it out, instead of on company/university time"? Or are the authors high profile enough in the community that it meets a certain threshold of credibility that it seems more worthwhile than the average?

Not much, see article (~1 day), or article + thread from yesterday. https://news.ycombinator.com/item?id=36864624
I don't think, at least generally, work is as rigid as indicated. At least at white collar jobs, and especially a research lab, and most especially a university research lab.

It's a reasonable enough paper, and replicating should be pretty easy (an undergrad could do it). Because the implications are so massive if true, people are going to jump on it.
From the linked article:
> You can bet that furnaces in solid-state materials labs around the world have been cooking yesterday and today to try to reproduce its synthesis and the properties, and we should be hearing about the results of these experiments very soon. The first samples should be coming out of the quartz vessels. . .sometime tomorrow, perhaps? Depends on what was available around the lab!

$10, $100, $1,000? 1 hour, 10 hours of labor?

South Korea has been waiting for a (real, STEM) Nobel prize for decades.
These guys will be worshipped as gods if they deliver

Yes, that quote from the article makes it seem like everyone is dropping everything and jumping right on it. I'm wondering how likely that is we'll find out this Friday vs. in the next couple of months, as people get around to it.

If i make an analogy to p=np.
If someone claimed to have a complex proof, i dont think people would stop and drop everything.
If someone claimed to have a constructive solution to p=np, claimed to have implemented it, and put the code on github - yeah i think lots of people would drop everything to run it and see if it works.
Im not a physicist, but maybe with the relative ease on making this material (according to other comments) it is more like the second situation.
