Quantum Quantum In physics, a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property may be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation). Similarly, the energy of an electron bound within an atom is quantized and can exist only in certain discrete values. (Indeed,
Australasian College of Physical Scientists and Engineers in Medicine 1986. The ACPSEM facilitates training and professional accreditation for practising medical physicists in Australia and New Zealand. This includes significant support for the TEAP training program for medical physics trainees. The ACPSEM also promotes education and research into the biomedical applications of physics, mathematics, engineering and computing. The ACPSEM has an official scientific journal, Australasian Physical & Engineering Sciences in Medicine, which is published 4 times a year. The ACPSEM holds an annual Engineering and Physical Sciences in Medicine conference, and has done every year since 1961. The ACPSEM is governed by an elected board known as the ACPSEM Council,
