philosophy of physics

Basically there is no physics experimental evidence that can make one formulation or interpretation distinguish itself from others.

9 formulations of quantum mechanics

  1. Matrix - Heisenberg
  2. Wave function - Schrodinger
  3. Path Integral - Feynman
  4. Phase Space - Wigner
  5. Density Matrix
  6. Second Quantization
  7. Variational Formulation
  8. Pilot Wave - de Brogile-Bohm
  9. Hamiltonian-Jacobi

5 Important Aspects of an interpretation

There are many standards to evaluate a theory, there are 5 most important ones.

  1. Determinism?
  2. Is there are Hidden Variables?
  3. Do wavefunction collapse?
  4. What is the role of observer?
  5. Locality?

6 basic interpretations of quantum mechanics

  1. Consistent History
  2. Copenhagen
  3. De Broglie-Bohm
  4. Everett
  5. Information based
  6. Objective collapse (GRW / Penrose)
