Discover Leibniz's Stepped Reckoner in Hanover, Germany: An extraordinary mechanical calculator designed by the mathematician and philosopher Gottfried Leibniz. The Leibniz Step ReckonerGottfried Leibniz’s 1673 “Step Reckoner” introduced a design innovation that enabled a single gear to represent any digit from 0 to 9 in just one revolution. [2], Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably.[3][4]. Accordingly, he eventually designed an entirely new machine called the Stepped Reckoner; it used his Leibniz wheels, was the first two-motion calculator, the first to use cursors (creating a memory of the first operand) and the first to have a movable carriage. The basic operation performed is to add (or subtract) the operand number to the accumulator register, as many times as desired (to subtract, the operating crank is turned in the opposite direction). This stepped-drum approach dominated calculator design for the next two centuries. Though Aristotle spoke of “energeia” in the fourth century BC, the Greek word was not directly translatable. The first (least significant) digit of the. Figure 3. ?tte, 1894. Its fine workmanship and impeccable mechanism wouldn't be matched for more than 1000 years.
