Uncharted, Unexplored, and Unexplained: Charles Babbage

In 1815, there weren't any computers. Electricity hadn't yet been discovered as a way to make things run. Calculating sums of numbers had to be done by hand. One mistake would mean adding everything up all over again. But English scientist Charles Babbage was planning to change all that. He planned to use his knoweldge of mathematics and engineering to build a machine that would be able to work out the most complicated sums instantly. But someone would have to give it the right program to follow.
