Radar?
How about Radar. Uses doppler principles and the maths isn't too intense. I carried out an undergraduate project last year to build a range detecting radar set up. It's interesting and good fun to build. Needs some electronics knowledge though.

Hello,
Does anyone know why in pionic hydrogen the strong interaction should be attractive whilst in kaonic hydrogen it is repulsive. I have heard it is something to do with a sub-threshold resonance but nothing more.
Thanks
