The other class took theirs on Friday and has started BFPM. Today was supposed to be about learning to draw a useful FBD.But then they asked some really interesting questions, so instead of practicing FBDs, we talked about theories of gravity, FTL neutrinos, and the nature of science. Well, we didn't call it the Nature of Science, but we talked about evolving knowledge and not having a final answer, with a mention of experimental error and needing confirmation of an astounding result. It was fun (at least for me).
- Leaping "off-topic" in response to a good student question always engages students.
- Everything we talked about was either topical or timeless. Most of it ranged from genuinely puzzling to mind-bending. (If your mind doesn't bend while thinking about General Relativity or FTL communication, you're not thinking about it hard enough.)
- We didn't practice using FBDs.
