Classical Derivation of Planck's Radiation Law and Planck's Constant

Causal classical derivation of Planck's black-body radiation law is presented. A novel physical meaning of Planck's constant as Lorentz-invariant product of the energy and space-time interval of photons is introduced. It is shown that h can be derived, and its numerical value can be calculated from classical physical quantities, furthermore that the physical meaning and the numerical value of the fundamental quantum constants; quantum Hall impedance, magnetic flux quantum, and the fine structure constant can be derived and calculated from classical physical quantities.
