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 Germany adjusted every two years by the German government which is consulted by a minimum wage commission. Thus, the minimum wage was at 8.84€ per hour in December 2018 and is expected to rise up to 9.19 in 2019 and to 9.35€ per hour in 2020. In order to adjust the amount of the minimum wage, the German government implemented a permanent commission, which is composed of nine commissioners. The panel includes a president, three workers’ representatives, three employers’ representatives and two economist advisors that do not have voting rights within the commission. It assesses Germany’s overall economic performance to evaluate
