The career of a young theoretical physicist consists of treating the harmonic oscillator in ever-increasing levels of abstraction.
I was very eager to produce an oscillator for short waves. I was doing science with microwaves, and I would get down to a few millimetres in wavelength, but I wanted to get shorter wavelengths; I wanted to get into the infra-red because I saw there was a lot more to be done there.
A badly designed oscillator circuit may suddenly begin oscillating on an overtone.
A crystal oscillator depends for its frequency on its physical dimensions, which vary with fabrication and environmental conditions.
A consequence of these activity dips is that the oscillator may lock at a spurious frequency at specific temperatures.
Adding or removing bosons from each state is, therefore, analogous to exciting or de-exciting a quantum of energy in a harmonic oscillator.
