This is the best state of affairs sum up at the moment and my favorite plot line is the soil scientist. https://twitter.com/8teAPi/status/1685960703658860544?s=19

Can we put this LARPing scam artist out of the conversation? They are setting up a bitcoin wallet to, "raise money" to post a video of their admitted non-replication (They didn't use the original replication steps at all), but still superconducting result using kitchen cookware? Also they spend more time promoting bizarre Soviet propaganda, furry porn, and LARPing than science. Please, can we stop taking this serious…

Who’s taking it seriously? It’s fantastic armchair entertainment.

There's a certain subset of people on the intersection of high IQ, high-functioning ASD and LGBT that produces a lot of high impact activity in STEM fields.

High-functioning LGBT for sure

Do you have a point or did you just feel like inserting your homophobia?

Iris Alexandra's twitter is especially enthralling. Seems like so much discoveries and innovation happens from computer science to physics, chemistry and biology all from people with anime profile pictures.

She's acknowledged her results were a hoax at this point.

I haven't seen any such acknowledgement in her twitter feed?

Don't get me wrong, I want to believe (tm) as much as anyone, but this particular part of the story has a lot working against it: * This person is anonymous (account created in Apr 2023), so we don't know anything about their affiliation or credentials. * They do seem to have good knowledge of materials science (although I have no way to judge), but the rest of their twitter history, which is all we have to go on, do…

If 1000 people with geeky interests all try to make this stuff I would be surprised if one did not get lucky with the variations in their uncontrolled home lab environment and hit the perfect sequence for making a grain of it... unless the material does not exist; but honestly if you want to hear the opinion of some person on the internet, I think that it is real.

That may be true, but I'm not seeing 999 other people with geeky interests reporting their failed attempts. We are, however, starting to see actual labs reporting negative results.

I've only seen one picture of an alleged successful replication yet: https://twitter.com/iris_IGB/status/1685731177523449856

The author has acknowledged that one as a fake.

Where? I haven't seen that in her twitter feed.

Prediction markets got Donald Trump wrong on the election night and Brexit too[0]. Given such a huge failure why should we care what they say? [0]: https://archive.li/7m8s6

Are you saying they are no better than chance? Or just that they are not 100% perfect? Because we should deeply care about any source of information that beats chance, even if it is imperfect.

I mean that is two fucking big ones to get wrong, no?

Would maybe be interesting to see some data to look back and see how correct they are in general, but to be practically useful it would have to be quite a lot better than chance.

As I learned from the Dave's EEVBlog video [1], their demonstration video [2] says in the description that the material was deposited onto a copper plate which could probably explain the interaction with the magnet. And as I just noticed, the description has since been changed and now says »The sample was thermally deposited on a enriched uranium 235 plate.« EDIT: Correction, I got the link to the video saying deposi…

That's highly suspicious. I guess they're banking on nobody having an enriched uranium 235 plate at hand to verify what happens if you do this without any LK99...

Its not like nobody has ever investigated the magnetic properties of uranium. You could just look it up.

The first time it demonstrated superconductivity they dropped the quartz tube it was in, cracking and accidentally oxidizing it at a specific point in the heating process and providing vibration that caused the formation of a crystal structure in the material. That's... not easily replicable.

I hope this doesn't end up like a physics equivalent to Fermat's Last Theorem

That would be better than the physics equivalent of cold fusion (which seemed promising at first, but turns out to not exist - at least so far). Only time will tell, though if it really is, but so difficult to replicate that we need a few hundred years it may as well never exist for purposes of our lifetime.

So, Russian anime cat girl seems to have cooked a sample and demonstrated some of the claimed properties, although she's explicit that it shouldn't be considered a "replication". https://twitter.com/iris_IGB/status/1685731177523449856

By their own admission, they've messed with the prep and synthesis stages mentioned in the paper: https://nitter.net/iris_IGB/status/1685774956330635264#m Also, forgive me for taking this person's word with a massive grain of salt when they post stuff like this: https://nitter.net/iris_IGB/status/1686017042665582593#m

huh lol ... Well she obviously has the time to tweet a lot of sh*t while being much faster than any other team on earth. She alone from the USSR must still be the primary (progressive) power worldwide ... who knows ...
