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…

It's really disappointing that no other US lab has engaged with the public in the same manner. Regardless of the outcome, I think seeing things get built and experimented with in mostly real-time is a massive source of inspiration.

the difference between doers versus academics has never been demonstrated more beautifully

The problem is they needed academics to show them what to do.

There is a Checz lab also documenting the process https://twitter.com/CondMatfyz

I am totally confused, it is documented in the original south korean paper, why anyone would want to rely on such second hand unverified info when first hand info from the original inventors are freely available to everyone?

the really amazing part of the LK99 is that you don't any big name with access to some national labs to demonstrate that for you, all you need is some high school lab equipments and some very basic understanding of the subject.

Yes and no. You still need access to red phosphorous which is not all that easy to get hold of.

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

If not logged in, Twitter shows no replies, not even ones in the same thread.

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

Oh yeah, the commercial "doers" are happy to have a go once academics have slogged away at the hard, risky, expensive, and often thankless trial-and-error before the discovery. Not to do down the people in this particular example, and I'm happy to assume they aren't claiming any credit they shouldn't, but the dichotomy really isn't as you make it out to be.

Twitter isn’t loading at all for me at this moment. No idea if it’s me, or twitter or being logged out or logged in or what.

Nitter let’s me see the content instantly.

That's not entirely accurate. For my understanding, it is a private institution which employed the individuals who made the discovery. Some of whom have alternative backgrounds in academia, and some of whom have it in industry.

100% true and actually a very interesting statement. Can you imagine if he had tried to present this idea to the c-suite as a potential marketing or PR coup?!

Do we really care if they confirm it in a week or two ? Are we on a hurry ? I don't know anything bout supraconductors but given the number of failing attempts to repicalte (and the number succeeding), I would not be suprised if it'd take quite some time before we can be certain. Moreover, we'll need a consensus among all the people who understand the subject. So, a week or even a month won't make any difference. We'…

As engineers we are given building blocks that we can build things from. Iron, steel, copper, plastic. Every once in a while a new building block arrives. It takes a while for us to figure out how to use it. But when we do, the world changes.

- batteries + touch screens => iPhone

- batteries got better => Tesla

- reinforced concrete => pretty much all the worlds buildings and bridges

- neodymium magnets + gyros => drones

A room temperature superconductor... well, that changes things on a completely new level. Order of magnitude smaller losses plus order of magnitude higher magnetic fields? OMFG can we build SciFi things from this if it pans out.

So yeah - we are in a hurry. If this pans out, there will be a massive shift in how pretty much anything is made. And the reward for the people who can figure it out first are insane, in terms of potential value created.
