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 the United States Hispanics supporting a $15.00 federal minimum wage, and 54% of whites opposing it. A Lake Research Partners poll in February 2012 found the following: This is a list of the minimum wages (per hour) in each state and territory of the United States, for jobs covered by federal minimum wage laws. If the job is not subject to the federal Fair Labor Standards Act, then state, city, or other local laws may determine the minimum wage. A common exemption to the federal minimum wage is a company having revenue of less than $500,000 per year while not engaging in any
