Invention of Computers
It all started a long time ago, in the 19th century, when clever people like Charles Babbage and Ada Lovelace had really smart ideas about making machines that could do complicated math. They called these machines the "Difference Engine" and the "Analytical Engine." But it wasn't until around World War II that things really started to take off. The war made people realize they needed machines that could do math really fast to help with important things like planning battles and decoding secret messages. In 1941, a guy named Konrad Zuse made what many people think was the first real computer. It was called the Z3, and although it was big and clunky, it could do math without people having to do it by hand. Then, in 1946, another big moment happened when a super-smart machine called ENIAC was born. It was huge and filled up an entire room, but it was super fast at doing math. After that, things started getting smaller and faster. In 1947, someone invented somethi...
