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
Minimum Wage in Germany adjusted every two years by the German government which is consulted by a minimum wage commission. Thus, the minimum wage was at 8.84€ per hour in December 2018 and is expected to rise up to 9.19 in 2019 and to 9.35€ per hour in 2020. In order to adjust the amount of the minimum wage, the German government implemented a permanent commission, which is composed of nine commissioners. The panel includes a president, three workers’ representatives, three employers’ representatives and two economist advisors that do not have voting rights within the commission. It assesses Germany’s overall economic performance to evaluate
