(P1 + P2)2 - 4P1P2 = (P1 - P2)2 (A - B = C)

The reflection and transmission probabilities are

R = C/A

T = B/A

Can one understand this from the first equation?

Is the first "equation" one or two equations? It is written a bit unconventionally.
 
That is not an equation. Are the brackets in the right places?
 
i just wrote A - B = C
to label the terms in the equation.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
