Been following this very closely. Seems like the one takeaway is that whatever material this is, it's interesting. It's also difficult to synthesize in bulk, which is a shame because superconductivity is not easy to observe in non-bulk materials (think: powder).

Assuming LK99 is legitimate, my hope is that the principles that make it work are more broadly applicable - and with that, refined production processes or newer alloys can be found.

I wonder what was involved in the discovery of stone.

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.

> anime profile pictures

Either that or furry ones. Amusing apparent correlation.

This live crowdsourced approach is a far better way to test and refine hypotheses than peer review and the current state of science journals.

requires a really significant result in order to demand widespread effort in to replicate.

Highlighting this tweet in particular:

> Here's a chunk of pyrolytic graphite on the same magnet with the same stick. Even with less density and more surface normal to field.... It doesn't lift off. If it's diamagnetism it's a fucking absurdly strong one

Her findings, and suggestions of manufacturing process improvements, are very interesting.

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.

Could this be the new 4 minute mile? Will [humanity] evacuate on ourselves? Whatever this may be, it’s exciting.

I don’t know what you’re trying to say, but to “evacuate on ourselves” means to shit ourselves.

That is exactly what I intended to say.

Everyone thought the 4 minute mile was impossible, until it was done, and then everyone started doing it. Had Roger Bannister had a cardiac arrest and evacuated on himself, people would have stopped trying for it.

Why is it hard to make in bulk? I thought the chemicals were easy and cheap to obtain, and then you bake it at a high temp? What makes it difficult?

Evolution of enough intelligence to use stone as a club, or make an edge on flint for cutting?

A rigorous peer review by graduate students.
