Aug 24, 2020 at 5:30 comment added anna v It is mathematics. Once an interaction occurs, visualize the feynman diagram , the outgoing particles energy momentum four vectors, are free to enter into another interaction, they no longer have a "memory" of the first. The individual event behavior cannot be predicted, what is predicted is the cummulative behavior of same condition interactions for which the probability distribution is determinable. Look at this single event interaction . The vertex is where the quantum behavior is calculated, ant the probability predicted. A great number of exact events have to be measured to get the probab
Aug 24, 2020 at 5:13 comment added smallest quanta in you 3rd paragraph, do you mean that, if we try to do position measurement on a particle in superposition state, then its wavefunction will collapse to delta function, but since the momentum is uncertain, we cannot tell anything about the second measurement ( since the particle has left that place while interacting with photon)?

Apr 18, 2018 at 14:38 comment added Acccumulation It's the absolute square, not the complex conjugate squared. The complex conjugate squared is just the conjugate of it squared.

Apr 18, 2018 at 3:44 comment added anna v @Acccumulation it is the complex conjugate squared
Apr 17, 2018 at 22:03 comment added Acccumulation Isn't it $\overbarΨ∗Ψ$?

minor spelling
Apr 17, 2018 at 4:03 comment added anna v @BenCrowell I mean the exact real numbers that have to be introduced in the mathematical formula so that the results can be compared with data from an experiment, as, for example, dimensions and distance between slits, in the double slit experiment and energy of the photons. Input energies and momenta in scattering etc.
Apr 16, 2018 at 20:03 comment added user4552 they only prediction they give is a probability distribution, which depends on the boundary conditions of the problem This doesn't make much sense. What do boundary conditions have to do with this? Do you mean boundary conditions in the sense in which the phrase is normally used in mathematics, or in some looser sense?
