Computer.
When Ch. Babbage, a professor of mathematics at Cambridge University, invented the first calculating machine in 1812 he could hardly have imagined the situations we find ourselves in today. Almost everything in modern world is done with the help of computers - the complicated descendants of his simple machine. Computers are being used more and more extensively in the world today, for the simple reason that they are far more efficient than human beings. They have much better memories and can store great amount of information and they can do calculations in a fraction of the time required by a human mathematician. No man alive can do 500,000 sums in one second, but a modern computer can.
In fact, computers can do many things we do, but faster and better. They can control machines at factories, work out tomorrows weather and even play chess, write
