could someone explain this paragraph taken from "concepts of modern physics" by arthur beiser pg175? I'm having trouble understanding it...
"A dynamical variable G may not be quantized. In this case, measurements of G made on a number of identical systems will not yield a unique result but instead a spread of values whose average is the expectation value
<G>=(integrate) G(psi^2)dx"
and why if the electron's position in the hydrogen atom isn't quantized, we have to think of the electron in the vicinity of the nuvleus with a ceratian probability?
