  • It’s easy to get caught up in the negativity of the LK-99 claim being disproven, but I think there are many positive aspects of this affair that are worth pointing out.

    1. Multiple top labs, including some of the very best cond-mat groups in the world (e.g. Bernevig), were willing to spend time checking out the claim, even though the Korean group were mostly nobodies. People went in with an open mind, and were very calibrated and professional in their criticisms… even when the substance of the criticism was scientifically devastating, like the CAS preprint pointing out the role of Cu2S. This speaks to an egalitarianism in this scientific community that’s wonderful and worth celebrating.

    2. The fact that so many top groups were willing to check this out, on the off chance that LK-99 really was the real deal, demonstrates how real the possibilities are. We honestly don’t know if a room temperature and pressure superconductor is possible; LK-99 isn’t one, but it could very well be that tomorrow someone discovers one. Materials science still has lots of potential, and the dream is still alive!






  • Technically, all ships with a functioning command structure are dictatorships. It’s not analogous at all to systems of government for a whole society. In nautical tradition, the captain on his deck is more powerful than the king and pope combined. Things are watered down a bit more nowadays with military regulations, etc., but the point remains that it’s nothing like how civilian societies function.
