## Main Question or Discussion Point

I saw this Einstein, Podolsky, Rosen paradox in one of my textbooks and it is very interesting. The paradox simply challenges the Copenhagen (Orthodox) Interpretation of Quantum Mechanics by using the constancy of the speed of light.

It simply states that if we observe a pi meson decay into a positron and an electron, then wait long enough that

{delta}x >> ct

and measure the spin of the electron, we are going to collapse both the wavefunction of the electron and the positron. If we find the electron spin to be +1/2 the positron spin will be -1/2.

Thus it is claimed that then information will be carried over much faster than the speed of light which is not possible, so they conclude that the electron and the positron had definite spins prior to the measurement.

What do you make of that?

P.S. I would also be glad if someone would provide me a good source showing how Schroedinger came up with the Schroedinger Equation, I have looked at a bunch of books and could not find one, I am really curious about that.

P.S. How do you implement latex code in your messages???

Thanks.
