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
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
