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
Physics (American Physical Society magazine) Physics (American Physical Society magazine) Physics is an open access online publication containing commentaries on the best of the peer-reviewed research published in the journals of the American Physical Society. The editor-in-chief of "Physics" is Jessica Thomas. It highlights papers in "Physical Review Letters" and the "Physical Review" family of journals. The magazine was established in 2008. "Physics" contains three types of commentaries on research papers: journalistic articles ("Focus"), in depth pieces written by active researchers ("Viewpoints"), and short summaries of a research paper ("Synopsis") written by editorial staff. Readers get free access to the underlying research papers on which
