IV: Relativistic Quantum Mechanics

  • Page ID
  • This volume gives an introduction to incorporating special relativity in quantum mechanics. That is, described here is a theory which includes Einstein's and Heisenberg's relationships. How does relativistic quantum mechanics differ from non-relativistic quantum mechanics? That is, what new feature does special relativity bring to quantum mechanics? The answer lies in the possibility of converting energy to mass and vice versa.
