Nikon has developed what I consider the best representation of base ten exponential representation I have ever seen.
Universcale allows you to navigate a two dimensional Base 10 landscape linearly.
I see the possibility here to develop a visual model to linearly navigate any pair of exponential scales.
I can also see the possibility to develop a visual model to tabularly navigate any pair of exponential scales.
Truly a brilliant innovation that deserves to be extended to its fullest potential.
I highly recommend a visit.
