A photon, for example, is a single quantum of [[light]], and may thus be referred to as a "light quantum". The [[energy]] of an [[electron]] bound to an [[atom]] (at rest) is said to be quantized, which results in the stability of atoms, and of [[matter]] in general.

As incorporated into the [[theory]] of [[quantum mechanics]], this is regarded by physicists as part of the fundamental framework for understanding and describing [[nature]] at the infinitesimal level, for the very [[practical]] [[reason]] that it works. It is "in the nature of things", not a more or less [[arbitrary]] [[human]] preference.
