Difference Engine No. 1

Difference Engine No. 1, designed by Charles Babbage in the 19th century, is an early mechanical calculator that could compute and print mathematical tables. It used a series of gears and levers to perform addition and subtraction automatically, relying on the principle of finite differences to handle more complex calculations. This revolutionary machine aimed to eliminate human error in mathematical computations and is considered a precursor to modern computers, showcasing the potential of automated calculation long before electronic technology emerged. Although never completed in Babbage's lifetime, it laid important groundwork for later developments in computing.
