History of variational principles in physics involves integrals over an interval of time and (for fields) extended region of space. Moreover, in the usual formulation of classical action principles, the initial and final states of the system are fixed, e.g., In particular, the fixing of the "final" state appears to give the action principle a teleological character which has been controversial historically. This apparent teleology is eliminated in the quantum mechanical version of the action principle. History of variational principles in physics A variational principle in physics is an alternative method for determining the state or dynamics of a physical system, by identifying it as an
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
