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
Amount in controversy $75,000 in 1996. The use of the word "exceeds" in Section 1332 implies that the amount in controversy must be more than $75,000; a case removed from state court to federal court must be remanded back to state court if the amount in controversy is exactly $75,000.00. Congress did not create a consistent federal question jurisdiction, which allows federal courts to hear any case alleging a violation of the Constitution, laws, and treaties of the United States, until 1875, when Congress created the statute which is now found at : "The district courts shall have original jurisdiction of all civil
