13 Black-body radiation and Planck`s formula
... of Planck’s formulation of the Second Law is this: Since a system in thermal and mechanical isolation is known to evolve toward thermodynamic equilibrium, then in this equilibrium, the system’s entropy must be a maximum. It is this connection between a thermodynamic equilibrium and the entropy that ...

The relation of W to the action S is basically that one trades the time t for the energy E, by making a so-called Legendre transform. More on this can be found in “Classical Mecha ...

Feynman Diagrams for Beginners
... To describe kinematics of some physical system or event we are free to choose units of measure of the three basic kinematical physical quantities: length (L), mass (M) and time (T). Equivalently, we may choose any three linearly independent combinations of these quantities. The choice of L, T and M ...
