He didn't even try to hide the imperfections in his idea. In his Nobel lecture Feynman said: *"I don’t think we have a completely satisfactory relativistic quantum-mechanical model, even one that doesn’t agree with nature, but, at least, agrees with the logic that the sum of probability of all alternatives has to be 100%. Therefore, I think that the renormalization theory is simply a way to sweep the difficulties of the divergences of electrodynamics under the rug. I am, of course, not sure of that."* He is also well known for saying: *"**I think I can safely say that nobody understands quantum mechanics."* John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
