N2 - The quantum mechanics courses include semiclassical methods based on certain representation of the wave function, starting with the celebrated Bohr–Sommerfeld quantization condition, applied to the oscillator and hydrogen atom, and the Wentzel–Kramers–Brillouin (WKB) approximation, developed in 1926. Unfortunately, subsequent study has shown that generalization of those to systems with more than one degree of freedom, as well as to systematic order-by-order account for quantum fluctuations are difficult.
