High Quality Content by WIKIPEDIA articles! In physics, a quantum (plural: quanta) is the minimum unit of any physical entity involved in an interaction. An example of an entity that is quantized is the energy transfer of elementary particles of matter (called fermions) and of photons and other bosons. The word comes from the Latin 'quantus', for 'how much.' Behind this, one finds the fundamental notion that a physical property may be 'quantized', referred to as 'quantization'. This means that the magnitude can take on only certain discrete numerical values, rather than any value, at least within a range. There is a related term of quantum number.
