Antibiotics Antibiotics transformed medicine. The discovery of antibiotics began by accident. On the morning of September 3rd, 1928, Professor Alexander Fleming was having a clear up of his cluttered laboratory. Fleming was sorting through a number of glass plates which had previously been coated with staphyloccus bacteria as part of research Fleming was doing. One of the plates had mould on it. The mould was in the shape of a ring and the area around the ring seemed to be free of the bacteria staphyloccus. Further research on the mould found that it could kill other bacteria and that it could be given to small animals without any side-effects. However, within a year, Fleming had moved onto other medical issues and it was ten years later…show more content…
They wanted to devise an inter-networking system (or internet) whereby different networks could ‘talk’ to one another. Arpanet devised TCP/IP (Transmission Control Protocol/Internet Protocol). This was a set of rules for communication between networks. The Internet became a network of networks. Only the military stayed outside of this for security reasons. In 1988, there were 50,000 computers attached to the Internet. By 1991, there were 1 million. However, it was difficult to access the information contained on the Internet as the system had little organisation. This problem was solved by Tim Berners-Lee, a British scientist studying at a research facility in Switzerland. He invented a method of organising information which he called the world-wide-web (www). His system linked documents from different sources and guided users to related information. The www was first used by the public in 1991 and it allowed the transfer of text, sound, images and video clips. Above all else, it was simple to use. In 1998, 130 million people were using the Internet and the figure continues to grow annually. The Jet Engine Sir Frank Whittle's jet engine transformed travel. The jet engine has allowed millions of people now to do something that was barely thinkable just 70 years ago - crossing the Atlantic at speed. The Wright’s may have invented the first real aeroplane, but the credit for the invention of the jet engine goes to Sir Frank Whittle. In 1937 he
