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 Minimum Wage in Germany Germany’s minimum wage legislation - "Gesetz zur Regelung eines allgemeinen Mindestlohns" - was introduced, on January 1, 2014, by Merkel’s third cabinet, composed of a coalition between the SPD – the social democratic party - and the CDU – the conservative party. The implementation of a minimum wage was the SPD’s main request during the coalition’s negotiations. Indeed, it was its central electoral promise during the 2013 federal elections’ campaign, to replace negotiated wages within branches that were previously set below the current minimum wage, Initially, the minimum wage was set to 8.50€. Its amount is
