Variation principles (de)

In this article variation principles in modern physics  are reviewed. Thes principles are used to derive equations of motions and are therefore of fundamental importance. This article focuses on the comparison between the classical variation principle used in modern physics and my approach of a new variation principle. The major difference are:

classical variation principle for mass points

  • requires known boundary conditions 
  • requires the use of energy conservation 
  • quantization of energy in quantum mechanics

my new variation principle for mass points

  • does not require precisely known boundary conditions (e.g. is valid for continuous systems).
  • requires only particle number conservation (e.g. annihilation of particles such as e- and e+ annihilation is forbidden)
  • does not require the principle of energy conservation (!!!)
  • does not require the quantization of energy in quantum mechanics
