If it doesn't filter frequencies, does it filter amplitudes? So (a) will filter out everything brighter than something, and (b) will filter out everything dimmer than something?
It does filter frequencies. Not time frequencies, though.

Spatial frequencies? i.e. wavenumbers / lengths? Surely that's the same as filtering time frequencies or colour?
I can't think of any other types of frequency

was it one of fermat's theorems?
Describe the form of all integers that are sandwiched inbetween a perfect square and a perfect cube.
(i.e. all x such that a*a*a+1 = x = b*b-1 or a*a+1 = x = b*b*b-1). [with a, b integers too of course]
Who first proved this?
