Inventions
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.
