The computer was invented in the 30s: not the 1930s, but the 1830s. British mathematician Charles Babbage designed and prototyped a fully functional mechanical computer he called the Analytical Engine, but it was never completed. Now a team in Britain plans to build the machine for display at London’s Science Museum before the 2030s come around.
