Small-Scale Question Sunday for July 23, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

A claimed Chinese replication at very small scale and low purity showing reaction to magnet, some fascinating theoretical approximations that have give a weakly plausible theory, albeit with many limitations, and a number of failed replication attempts. Manifold's floating 40%+ for replication by 2025; I'm a little more skeptical than that, still, but I'm not sure I'm skeptical enough to sell at those prices.

And a guardedly-optimistic summary from Derek Lowe.
