@AstroKatie Way back in the before times, I used to go to PI for public talks. I went to learn something, as they were generally presented in an accessible way. And I would occasionally bring our kids, hoping to engage them in whatever the topic was. I have to say, though, that my favourite talk was by Roger Penrose, even though by about a third of the way in he had completely lost me. But he has a wizard with overhead transparencies and it was mesmerizing to watch.
