Physics

Thomas explained it all, so go read that ;)

I was there too, played with the camera as well, obviously. In the difficult process of choosing which pic to upload to blip, i eventually thought it might be nice to blip one of the scientists instead of the science. I did, but now I changed it again. Choosing is hard :(

This plasma-ball was there to explain some concepts to the 'high shool'-students that were also there, but it also kept some older folks entertained ;)
