Over the years scientists have invented a great number of things, which we now use in everyday life, for example, computers, printing machines, telephones, radio, television, automobiles, photography, electricity, steam engine, planes etc. One of the most useful and handy devices today is the computer. It is a comparatively new invention, which came into use in the 20th century. However, the form of computer was designed already in the mid- 1830s by the British mathematician Charles Babbage. Today, people simply can’t imagine their lives without computers. There is a whole generation which has grown up with calculators, computer games, word processor, Internet and else. 

Another vital device is the TV. This invention has truly changed the leisure habits of millions of people worldwide. Television was pioneered in the 1920s by Scottish electrical engineer John Logie Baird. He was the first to realize that light could be converted into electrical impulses, which are then transmitted over a distance. Electricity, perhaps, is even more important. We wouldn’t be able to use computers and TVs without it. The invention of electricity dates back to the 19th century and is connected with such renowned names as Michael Faraday, Alessandro Volta, Humphry Davy and Andre Marie Ampere. For the invention of telephones we should be grateful to Alexander Graham Bell. He is an Edinburgh-born scientist who patented the invention of telephone in 1876. A year later a great American scientist Thomas Edison produced the first working telephone. 

The invention of different types of transport has also changed the world, for example, airplanes and motor cars. Planes have brought distant lands within easy reach of ordinary people. American-born Wright brothers were the first to make the flight in 1903. The first petrol-driven car was produced in 1885 by the German engineer Carl Benz. Whether we like them or not, cars have given people great freedom of travel. переводчик думаю имеется
