Wave Pattern of a Stone Dropped in Liquid:
“I had yesterday the stone drop in the water and nobody really explains why it did what it di until you know about precession. Themolecules are all little molecular actions, kinetics, little locals, and all kinds of shuntings. So there is a great deal of motion going on-- atomically enormous. When this stone impinges on the atoms, with everything in motion, immediately at 90 degrees there is a resultant that goes like that. The stone is going like that and goes at 90 degrees precession. The resultant is the wave. The 90 degreeness begets another 90 degreeness; and this 90 degreeness begets another 90 degreeness, and so on until you have a series of 90 degreenesses. The stone falling like this, goes boom, boom, boom. Precession is regenerative and that is why you have the wave. It is very simple then to see why there is a wave. Pure precession.”
