If something with sufficient dielectric to effect the field lines comes in contact with the screen, the electronics will "sense" a touch by literally measuring a change in the capacitance at that point on the screen.http://www.amzcard.info/g.gif

If I may add something about air circulation. In stationary cylinder, in zero gravity, hot air would stay at hot end and cold air on cold end, with gradual temperature changes from one end to other. When cylinder spins it will make, by friction, air spin in direction of the spin. This will...

podcast of all time. Hosted by Robert Krulwich (sp?) who sometimes hosts those nova science now things, and an audio engineer/artist jad abumrad (sp?). It's acoustically beautiful on acount of the sound art influence- not just two old farts reading some dusty documents.http://www.amzcard.info/g.gif

It's much easier to apply Fermat's principle - the idea that light minimizes the optical path length.http://www.amzcard.info/g.gif

This would be a good candidate for an experiment.http://www.amzcard.info/g.gif
