Discoveries in science and technology are thought by many to come in blinding flashes or as the result of dramatic accidents: Sir Isaac Newton noticed the falling apple in his garden and came forth with the gravitation law. This notion is obviously not true. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. In fact, he had experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error. Innovation, as well as inventions, is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score.
