Dirac equation in the algebra of physical space Dirac equation in the algebra of physical space The Dirac equation, as the relativistic equation that describes spin 1/2 particles in quantum mechanics, can be written in terms of the Algebra of physical space (APS), which is a case of a Clifford algebra or geometric algebra that is based on the use of paravectors. The Dirac equation in APS, including the electromagnetic interaction, reads Another form of the Dirac equation in terms of the Space time algebra was given earlier by David Hestenes. In general, the Dirac equation in the formalism of geometric algebra has the advantage of providing a
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,
