Difference Engine No. 2
The Difference Engine No. 2 was an early mechanical calculator designed by Charles Babbage in the 19th century. It could automatically perform complex mathematical calculations, particularly polynomial functions, by using a series of gears, levers, and wheels. Unlike manual calculation, it aimed to reduce errors and speed up computations, paving the way for modern computers. Its design marked a significant step in automating mathematical work, demonstrating how machinery could reliably handle calculations that previously required human effort. Although it was never fully built during Babbage’s lifetime, its innovative concept influenced future technological developments.
