Combinatorics and physics Combinatorics and physics Combinatorial physics or physical combinatorics is the area of interaction between physics and combinatorics. "Combinatorial Physics is an emerging area which unites combinatorial and discrete mathematical techniques applied to theoretical physics, especially Quantum Theory.". "Physical combinatorics might be defined naively as combinatorics guided by ideas or insights from physics". Combinatorics has always played an important role in quantum field theory and statistical physics. However, combinatorial physics only emerged as a specific field after a seminal work by Alain Connes and Dirk Kreimer, showing that the renormalization of Feynman diagrams can be described by a Hopf algebra.

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,
