The church thesis has been often criticized that is responsible for the difficulty of solving the P vs NP problem. There is a percentage of truth in it. The P vs NP problem has been considered important because there was the hope that we could prove that P=NP, in which case for many exponential time problems (all the NP=complete problems) there sho...

HOW TO DERIVE THE FORMULAS OF SPECIAL RELATIVITY WITHIN CLASSICAL GALILEAN RELATIVITY WITHOUT ASSUMING THAT NOTHING GOES FASTER THAN LIGHT OR THE THE LIGHT HAS THE SAME SPEED ON ALL INERTIAL SYSTEMS OF REFERENCE. THE LORENTZ INVARIANT LINEAR INERTIAL.

In this article we present a new simpler and physically more meaningful and intuitive principle of gravitation, which derives the Newtonian gravitation as a special case. It is based on the heat of the fieldmatter of the classical fields. Compared to the general relativity gravitation of Einstein seems to have at least the same experimental verific...

In this article we derive the Maxwell equations as linear approximations of more true non-linear equations of electromagnetism which in their turn are derived from the laws of newton in fluids. All it takes is realize that the molecular matter vacuum is not really material vacuum , it is filled with the fieldmatter (of the classical fields) which i...
