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.
