In a prior paper [1] we have presented a novel derivation of the special theory of relativity (STR) using only one principle, the principle of relativity. In the current note we present a novel, different derivation that is more direct.

In some situations nonlinearity seems to pervade in nature. Indeed, in adequate conditions, a minor action may give origin to a very large reaction, only apparently providing a gain in output power from a lesser inputted value. Extending de Broglie seminal ideas to a more general pilot-wave theory, we describe the relation between nonlinearity and energy conservation, dismissing any apparent contradiction between the two. We also present what seems to be a possible way to harness energy from the pervading subquantum medium.

This work presents the equations of motion on the basis of which the clear definition of the concept of mass is obtained and the classification of various variants of mass is revealed. Not only the fundamental equations of mechanics but the equations of electrodynamics and thermodynamics have been obtained with the use of the suggested equations of motion. It is shown that the universal constants of physics are the combinations of special dimensional coefficients introduced to impart the dimensional content to physical parameters, the numerical values of mentioned parameters are practically coinciding with the Planck units of length, time, mass and temperature.
