Your assertion is like saying some term in the Fourier expansion of a square wave exists.* *Yes but.... some terms in the Fourier expansion of a square wave DO exist. As I said in my previous post, there is almost always more than one way to derive something in physics or mathematics. * But those terms don't exist in the wavelet expansion of a square wave or many other decompositions of the square wave. So they only "exist" for certain interpretations of "exist". Brent Maybe someone can explain this; if, say, the momentum operator always returns an eigenvalue of the momentum of the system being measured, then when used in the UP, how can there be an uncertainty in momentum to give a statistical variance?

If you assume that virtual particles are real you are then able to make the most precise theoretical prediction not just in physics but in all of science, one part in 10 trillion. The theory of Quantum Electrodynamics, which is about virtual particles, predicted that the electron's magnetic moment should be approximately 0.001,159,652,181,643, the most accurate experimental measurement says it's approximately 0.001,159,652,180.* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
