## Main Question or Discussion Point

Frequency can be fourier-transformed into time and vice versa. They're inversely related.

In QM, momentum can be fourier-transformed into position and vice versa. But they're not necessarily inversely related. The uncertainty in time and the uncertainty in position merely have a lower bound.

So how do you determine how one variable can be fourier-transformed into another variable?
