It's IA time again, I don't mean with the second years, they finished ages ago, their work is all off loaded, I mean uploaded. No. it's time for the first years to get started. we've got as far as defining research questions and some preliminary dirtying of hands but that's all. having done this for many years I find it difficult not to dissuade student's from trying investigations that didn't work in the past, to be honest I should say I find it easy to dissuade them, I much prefer fresh ideas and here's one. It's the classic demo with a ball bouncing between two charged plates. Interesting motion, not SHM, turns out that the ball has pretty much constant velocity. I'll keep you updated.
