Pilot balloon slide rules were used by meteorologists in weather services to determine the upper wind velocities from an ascending hydrogen or helium-filled pilot balloon. [27] The E6-B is a circular slide rule used by pilots and navigators. Circular slide rules to estimate ovulation dates and fertility are known as wheel calculators. [28]
A slide rule scale is a line with graduated markings inscribed along the length of a slide rule used for mathematical calculations. The earliest such device had a single logarithmic scale for performing multiplication and division, but soon an improved technique was developed which involved two such scales sliding alongside each other.

Schumacher's original design, from which the Model 366 slide rule deviates only slightly Number table depicted on the slide rule. The A. W. Faber Model 366 was an unusual model of slide rule, manufactured in Germany by the A. W. Faber Company around 1909, with scales that followed a system invented by Johannes Schumacher (1858-1930) that used discrete logarithms to calculate products of ...
