Checking in: The effects of gravity are NOT slight. I am reminded of this every morning when I get out of bed. The effects of gravity are NOT constant. I am personally affected about twice as much now as when I was a teenager. I can attribute the change mostly to Pizza and Pepsi. The frequency of gravity is quite easy to measure by simple observation. Just watch the tide on a daily basis, and another harmonic related to the monthly lunar cycle. I did watch the video, and I find the guy to be quite enthusiastic. The variation he measures is far too small in magnitude to ever concern me.= .. But if I were the manufacturer of that frequency counter, I might be paying a bit more attention. And here's to wishing you all a wonderful weekend! :) --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
