According to many researchers, the very first computer in the world was invented by Charles Babbage. This man was fascinated by the idea of ​​creating a mechanical machine capable of performing complex calculations. In 1822, a small difference machine was designed and built, consisting of a huge number of levers and gears. Even then she could operate with 18-bit numbers. The accuracy of the calculations reached the eighth decimal place.

In the same year, the scientist began work on a larger and more advanced machine, but the technology of that time did not allow this to be done. Only in 1854, the Swiss Scheutz was able to build several such devices according to Charles’s drawings, and it weighed 14 tons.

By the way, Ada Lovelace, Babbage’s colleague and close friend, is considered to be the very first programmer in the world.
