Here is a neat visual demonstration of the principles of harmonic and non-harmonic pendulum waves. See the kind of toys you get to play with for $45,000 per year tuition.

John - that is fascinating.. I watched it 3 times and had my husband come over and watch it all the way through again... the idea that it is *all mathematical, and PREDICTABLE (by those who are into thast kind of math... weird and fascinating...
Am going to send the link later to my brother who was a research scientist (retired) from UpJohn... math isnt his specialty... but he may know of this harmonic thing and you know, its one of those things that if you mentioned to everyday people... its not a subject you get a response on LOL.... Thanks so much for posting that link. (sheeps)
