went to cafe scientifique. there was a really good turnout. there was also a speaker without any prepared notes, talking about a Hard topic (quantum mechanics and general relativity), fielding random questions at the start such as "Well, what about quantum tunnelling?" without really explaining the concepts involved. he needed a narrative, but instead was just rambling off the top of his head. lots of people left. including me.

we then went to firefly to meet avstrangegirl, alexa_jay and others. and then to the orange tree. nicely drunk now.

For this to be useful, of course, he needs to make predictions about relativistic effects on quantum scale.

I've wondered about the "spooky action at a distance" thing, because it says that as soon as you measure one particle, the other particle is in the same state, instantly. But GR rejects any notion of "now", ie an external chronological reference frame, as being invalid/nonsensical. It ought to be possible to do experiments involving spooky-distance-action and things travelling Quite Fast (in orbit would do), to see if there is an external chronology or whatever.
