'''Quantization''' (in British English '''quantisation''') is the  systematic transition procedure from a classical understanding of physical phenomena to a newer understanding known as [[quantum mechanics]].  It is a procedure for constructing  [[quantum mechanics]] from [[classical mechanics]].  A generalization involving infinite degrees of freedom  is [[Second quantization|field quantization]], as in the "quantization of the [[electromagnetic field]]", referring to [[photons]] as field "[[Quantum|quanta]]" (for instance as [[light quanta]]). This procedure is basic to theories of [[atomic physics]], chemistry, [[particle physics]], [[nuclear physics]], [[condensed matter physics]], and [[quantum optics]].
