Introduction to Quantum Mechanic
... It is not surprising to find that quantum mechanics does not predict the position of an electron exactly. Rather, it provides only a probability as to where the electron will be found. We shall illustrate the probability aspect in terms of the system of an electron confined to motion along a line o ...
