Classical Physics versus Quantum Mechanics
Observables are numbers.
All observables are independent.
Conjugate observables (potential/momentum) must have a non-zero commutator to quantize a field.
Observables are operators that act on the wave
function psi to generate a number.
Most observables are independent.
called the commutator
Conjugate observables are not independent.
