Slide x from 1/8 to 1024 along a ruler whose position is log₂ x. The ×2, ÷2, ×10 and ÷10 buttons show equal ratios as equal steps, with log₂ and log₁₀ readouts.
The claim above is what this widget demonstrates. Disagree with it?
On a log-scale ruler equal ratios of x are equal distances, so every ×2 moves the marker one doubling and every ×10 moves it log₂ 10 ≈ 3.32 doublings.
