Different scientists discovered different devices. But among all, there was a man who thought little more and tries to discover a new thing. From that, they can do almost all things. Do you know who was that person? He was Charles Babbage. Who wants to the discovered computer. But, Unfortunately, while working day by day he becomes blind. But although he did not give up and convince his junior to make they did not succeed.
