Some Families of Probability Distributions Within Quantum Theory
... Some basics of quantum theory are presented including the way an experiment is modeled. Then states, observables, expected values, spectral measure, and probabilities are introduced. An example of spin measurement is discussed in the context of Stern Gerlach experiments. In order to describe an exam ...

The Mystery of Matter: The Course
... If a photon is emitted from a moving source in my direction, do I see any effect from the moving source? Yes, if the source is moving toward me, the source is “pushing” the photon in my direction. That adds energy to the photon. Since the energy of the photon is E = h , the frequency n increases. I ...
