I found the problem of the ocsillating molecule interesting as well as the electron revolving around the nucleus, in both cases there is energy loss due to radiation and eventually the molecule will stop ocsilating and the electron will be together with the nucleos. the times when this happen are really low we got 10^-5 s for the molecule and 10^-38 seconds for the electron. If we get something like the age of the universe make sense, but those times are really fast! How to explain why the molecule doesnt stop oscilating? it actually oscialting?? I think that doesnt happen due to the uncertanty principle, that gives kinetic energy 0.5m(h/x)^2 when the position is localized, that could compensates the energy loss due to radiation?. but it actually radiates by the ocsilation (I now the QM description... hw and selections rules...) but what are the asumtions or facts that make classical electrodynamics fail a low scale????
