There is nothing special about the transmission and absorption of photons through a polarizing film. Exactly the same conclusions as those outlined above are obtained by studying other simple experiments, such as the interference of photons (see Dirac, Section I.3),
There is nothing special about the transmission and absorption of photons through a polarizing film. Exactly the same conclusions as those outlined above are obtained by studying other simple experiments, such as the interference of photons (see Dirac, Section I.3), and the Stern-Gerlach experiment (see Sakurai, Chapter 1; Feynman, Chapter 5). The study of these simple experiments leads us to formulate the following fundamental principles of quantum mechanics:
- Dirac's Razor. Quantum mechanics can only answer questions regarding the outcome of possible experiments. Any other questions lie beyond the realms of physics.
- Principle of the Superposition of St
