Scotland as a nation has been responsible for so many of the world's crucial inventions we rely upon today, without which the world would have been a very different place. The TV, and the telephone are probably the greatest advancements in communication since man learned to talk and write. Nowadays we can virtually talk to anyone on the planet with a mere phone call, and TV has become the most used method of communicating and entertaining to the masses. Medicine has benefited greatly from Scot's too, anaesthesia and sterilisation, two common surgical techniques we nowadays take for granted, revaloutionised medicine. Penicillin, the discovery of DNA, and many other things beside can be added to the list of medical accomplishments of Scotland and her inventors. For centuries now Scots have led the way in scientific breakthroughs, from Watt and his Steam Engine in the 18th century right through to the present day, with many new discoveries being made by Scots every year. It is a heritage to be proud of, and one which many Scots aspire to become part of.
