Descrição:

Differential analyzers were one of the main calculating tools in use for solving differential equation problems from the 1930s into the 1950s. Vannevar Bush´s Rockefeller differential analyzer (RDA2)was the most sophisticated analyzer of its time. Using a mechanical analogue computer design, powered by a wheel-and-disc mechanism the RDA2 read a paper tape describing the connections to be made, then automatically route the correct signals to the required equipment. The design of the machine was primarily for military use especially during WWII.
