In measuring the x component of angular momentum of a state, by using the expectation value calculation of Lx, i got i/3 h bar - i/3 h bar, does this means that the probability of h bar is i/3 and the probability of 0 h bar is 0 and the probability of -h bar is i/3...
Alleviating the almost century old confusion, the correct laws of statistics and logic pinpoint the true oddity of quantum objects: duality. As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal ...
This chapter first discusses statistical techniques and concepts — including probability, probability distribution, average and expectation value, and uncertainty — that are relevant to quantum mechanics. The physical interpretation of probability in quantum mechanics is then discussed. It is argued that ...
In order to understand the Schrodinger equation, you must know what the state vector is http://en.wikipedia.org/wiki/Quantum_state. Before we mesuare the system, its state could be any linear combinations of eigenvectors. The probability of obesrved value is square of the coefficient (also ...
Inquantum physics, a particle is considered to be an object that is localized in a physical space, i.e., 3-Dimensional Euclidean Space. The particle is described in terms of states, observables or expectation values these are given by vectors in Hilbert Space. Thus, this space aids in fin...

What is the quantum level? How to calculate expectation value in quantum mechanics? Which quantum number signifies the size of the electron cloud? How many calculations per second can a quantum computer do? How to determine magnetic quantum number What are quantum laws in quantum physics? I...
Expansion is Speeding Up, Supernovae Show Scientists previously thought that the universe’s expansion would likely be slowed down by gravity over time, an expectation backed by Einstein’s theory of general relativity. But in 1998, everything changed when two different teams of astronomers observin...
But all expectation values and hence all predictions agree with our first representation. And isn't this the only important thing? So what is the significance of unitary (in-)equivalent representations? It seems that I am missing a crucial thing here. quantum-mechanics hilbert-space ma...
PhysicsandSuch 39 2 First off, thanks for the response. by calculating the expectation value of F from -∞ to 0 you calculate the average value of the force the particle is likely to experience given it is on the left side of the potential well, and is described by the wavefunction ...
