You are describing the constant advancement of science I was telling you about. My argument is not with you, Jim. It is with the people who assert that scientific theories are never wrong - they just need new boundary conditions imposed from time to time. The evolution of the conservation of energy principle of which I am aware went like this: 1. Energy and matter are separate things and energy cannot be created or destroyed. (1900) 2. Matter can be turned into energy by splitting the atom so energy cannot be created or destroyed by ordinary chemical means. (1950) 3. Let's redefine matter as a form of energy - therefore energy cannot be created or destroyed. (2000) The theory was never wrong. :-) -- 73, Cecil, w5dxp.com |
