Oh, sorry, for statistics, i mean Statistical math along the probability theory ..

Hi at all, maybe it's a bit trivial. However, the question that i ask myself is ; that relation there is between statistics-probab theory & theoretical physics. What role does it play in theoretical research ? (apart from the probabilistic amplitudes encountered in qm) Thanks for the answers

so , correct me if I'm wrong, the wave-function represents the state of the particle as a localized wave packet..

therefore the waves of matter should be represented as localized waveforms of wave packets right ?

Hi at all, I've the following question: How the fondamental particles (electrons, protons) are seen as matter waves, what shape and size should be these waves? They are wave-packets?

Hi at everyone, why on wiki there is written: " According to modern understanding, the electron is a point particle with a point charge and no spatial extent. Attempts to model the electron as a non-point particle are considered ill-conceived and counter-pedagogic " I don't understand this...

Yes that i know, but i meant if it is necessary to study all Goldstein for good, for begin to grasp qm...

Hi at all. I'm wondered is necessary learn well analytical mechanic ( eg learning The Goldstein's book), for understand and study QM ?

Yes, Goldstein, I'm apologize for the mistake. Thanks for the suggestion !

Hi at all. According to you which of the two texts, between Landau-Lifshitz (mechanics) and the Goldberg (classical mech) is better for study Analytical Mech ? Or there are other better ones ?

Yes..

Hi at all, I've a curiosity about the role that the weight function w(t) she has, into the define of adjoint & s-adjoint op. It is relevant in physical applications or not ?

Sorry, I've been absent for a few days.. anyway yes, but how?
