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 a suitable minimum wage amount. The first minimum wage adjustment was made in June 2016, and was followed two years later by another adjustment, in June 2018, that rose the minimum wage to 9.19€. The minimum wage was one of the most controversial topics during the 2013 legislative election campaign. While the social democratic party - SPD, the green party - die Grünen and the left-wing party - die Linke, were in favor of a general minimum wage, the liberal party – FDP, and the conservative party – CDU, remained skeptical Leading economic research institutions, such as the CESifo Group
