I don't understand why she would be like this. Why would anyone hold back the production process for a material that could change humanity forever?

Why? Simple, there's lots of mentally ill people on this planet. Anime profile pictures are usualy a redflag. These kind of people should only be ignored since they never want to cooperate.

This isn't a big deal but to explain a bit why it came off wrong, sometimes I have a hard time socially and wish people would just explain their reactions instead of focusing on having the reaction: - It's not the first, to wit, the repro's author pointing out it looks the same as effect from China repro from...3 days ago? Time is elusive. - The Russian catgirl superconductor theory stuff is a blind alley, you've gon…

You could have just requested more contexts then. You instead picked three particular phrases, which are actually least relevant parts of the linked article, and concluded (or appeared to conclude) that my article is not worthwhile to read. It might be, but I want it to be worthwhile to read and your reply had no hints to avoid that. Especially given that the very point of my article is about providing those contexts…

Darn, didn't expect this. :(

I suggest revisiting this thread in a week.

I think you're joking, I'd 100% assume it, except that I ran into some truly bizarre US patriotism while trying to follow McCalip's updates a few days ago - last relevant one I could find was 'materials coming tomorrow' on 27th, but then I couldn't find anything about using them or any update. Just a decent into people tweeting (in thread) about how great America is, the best country, etc. Really surreal. Think it wa…

He’s replicating a cutting edge material science in his garage. People are celebrating the optimistic spirit of Americans. The indomitable will that this country encourages and the sense that anything is possible if you’re ambitious and smart enough to pull it off.

These are rather common. Often used in metalworking for steel hardening.

yeah but OP said 'high school lab'... which granted may be true in the US but certainly not what I'd call 'common' or even 'rare' where I live. a good description would be 'completely unheard of'.

>which granted may be true in the US

I'm a graduate of the public school system in the US in a state that is not in the top 10-15 for education - my high school had a pretty impressive furnace. I'm too far removed to remember what it's maximum temperature was but I wouldn't be surprised if it was 1000C+

This makes me extremely bullish about Varda Space, they have engineers of high quality and expertise that they could do a decent replication very quickly (if they got access to raw materials earlier, they might have been first to do so, comparable with the Chinese Groups) while working on their off time (from what I’ve seen of their twitter) and not a single big academic lab has managed to complete any sort of replic…

World first replication was done by Iris Alexandra using her own accelerated process and there is no way Varda Space could have beaten her.

I don't understand why people are attaching any weight to Alexandra's claims. AFAIK, it's a pseudonymous account that has provided no evidence that couldn't be easily faked. You might object that the evidence provided by the non-pseudonymous scientists could also be faked, but the key distinction is that they're attaching real, professional identities to their claims. There are reputational consequences to making things up. They have skin in the game. A pseudonymous account doesn't. Why should we believe them?

pardon my ignorance but why are people posting nitter links every time, what is wrong with original twitter urls?

How’s Nitter still working after all these recent restrictions from Twitter?

All I see from US academics on Twitter are debates about this and that. Borderline annoying. This is the first result from mighty US capitalist machine meanwhile 3 Chinese labs have published pre prints and Russian replicated it in her kitchen.

This, its utterly shameful. Hot takes here, hot takes there, skepticism here, tell people to calm down there. Yet not a single replication! China has gone through multiple failed and successful replications so far. And the first US replication is from an amateur. If LK-99 works out, expect some congressmen to use this as a bludgeoning tool against the state of US public science.

> If LK-99 works out, expect some congressmen to use this as a bludgeoning tool against the state of US public science.

I hope for the same here in Germany. It's way past time we actually deal with the sorry state of science funding and academia in general across the Western world.

The first pre-print came out on 22 July (if I am not mistaken). Not enough time has passed pure and simple. If I was an academic working on this, I would be following the Sagan Standard and triple checking my results before claiming anything. I think we are all suffering from 24 hour news cycles. The work in China and now Varda is very exciting but they are warp speed developments.

This is simply what post-peer-review looks like. Instead of a few anonymous peer reviews, you get the entire planet to replicate. Moment you get something meaningful, publish it on arxiv. Quantity, not quality is king. Anomalies are drowned out by large samples. Questionable methods get mass debated in public. Scientists are dependent on public funding, why squander the biggest moment in pop science for literal decad…

Only if you’re doing sexy science.

The peer review system is broken but I think we still need some sort of structured system in addition to this “hey world, check this out!” method.
