• Ever wanted to know how engineers made their calculations before digital calculators were on every workbench? • [Richard Carpenter] and [Robert Wolf] have just the thing-a sliderule simulatorthat can teach you how to do a whole bunch of complex calculations the old fashioned way! • The simulator is a digital recreation of theHemmi/Post 1460 Versalog slide rule. • This was a particularly capable tool that was sold from 1951 to 1975 and is widely regarded as one of the best slide rules ever made. • It can do all kinds of useful calculations for you just by sliding the scales and the cursor appropriately, from square roots to trigonometry to exponents and even multi-stage multiplication and divisions. • You can try the simulator yourselfin a full-screen window here.It’s written in JavaScript and runs entirely in the browser.
