This simulation partially mimics Richardson’s 1898 Slide Rule.
Make parts (semi) transparent, using the sliders,
for instance to see if the parts are essential,
or to compare the zigzag scale with a traditional logarithmic scale
save current settings as a URL
run a magnifier over the slide rule
The simulation can run in two modes:
drag: move the slide and cursor
click: the value at the position of a mouse click is shown in the digital display
