Andrew McCalip demonstrates synthesis of LK99

#52His piece of LK-99 is much bigger than the tiny grains I've seen elsewhere.
On the other hand, his piece is much smaller than two pieces we saw from South Korea.
Those are the original authors pieces, who obviously have secret know-how that they are going to sell for many $millions rather than give out for free.

pardon my ignorance but why are people posting nitter links every time, what is wrong with original twitter urls?
Twitter is basically broken if you don't login, compare this: https://twitter.com/andrewmccalip https://nitter.net/andrewmccalip In Twitter the latest tweet I see is from July, in Nitter is 22 minutes ago. Additionally in Twitter I get 3 notices/popups that I need to close.
We should discourage the use of walled-gardens for public discussion anyway. Otherwise nothing changes ever.

#54This 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…
the difference between doers versus academics has never been demonstrated more beautifully

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're not talking about a vaccine.
Re: Andrew McCalip demonstrates synthesis of LK99
#56the 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.

Does it help?

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…
It's jarring for us Euros (I dunno, ghosts of the war are still alive maybe?), but it's pretty normal stateside.

Someone asked: > If you were to cut off the part that isn't lifting, do you reckon the entirety of the floaty half would float? AKA is this semi-float thing a purity issue? And Andrew responded [0]: > We wanted to do rock surgery, but I was scared we would shatter our biggest piece. It definitely has a piece that isn't contributing lift. I'm guessing once they've prepared more samples and had existing samples tested…

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.
