JavaSlide

the WWW's very first Java Slide Rule

This Java applet implements a fully functional slide rule on your computer screen. The graphics may take some time to download, in the order of a couple of minutes.

The cursor and the slide may be moved with your mouse - just click and drag. The number overlay shows the reading and identification of the scale directly under the mouse pointer (or the hairline reading if over the cursor). Of course, with a real slide rule you must estimate these values by reading the scales! The scales here are accurately portrayed, so you can trust the readings. Note that slide rules do not maintain decimal positioning - you have to do that, too! The S&T scale is slightly off due to the different ways that I, and the original manufacturer of this rule, have calculated the values.
