Stretch this wavelength out until it is a line. The stretch it took to become a line is our scale. Retain this information.
Before coming to this, and with each stretching, more and more data is lost. At key points, much data falls off at the same time. We retain this information. Repeating is common in compression algorithms. We can re-run an algorithm a number of times. Like sanding a wall to paint then sanding again.
It was a musical thing, you see. Focus on Hz and it’s all about that PHI, baby.
More on this, perhaps, later on…
