Introduction to Quantum Physics (M.I.T. Introductory Physics Series)

We know that classical physics, as represented by Newtonian mechanics and Maxwell’s laws of electromagnetism,
works marvelously well for the analysis of the behavior of
macroscopic objects in terms of empirically determined laws
of force. But as soon as we enter the world of the atom, we find
that new phenomena appear, requiring new concepts for their
analysis and description.
