Hermitian Operators
Quantum Mechanical operators are hermitian. If a quantum mechanical operator is represented by a matrix then so that is equal to the complex conjugate transpose of For example, the spin Pauli operators may be represented by the matrices Every quantum...

Quantum physics has as it's root that every particle may be described by a wavefunction. The wavefunction – which describes the motion of the particle – has no real physical interpretation. In general the wavefunction may take non real or imaginary...

The Bohr model gave a picture of the hydrogen atom which was very successful, explaining all the lines in the spectrum then known, and predicting more which were found. It put on a semi theoretical basis the Rydberg formula, which until then had been a...
