Excerpt. In 1819 a danish physicist. H. C. Ostered was carrying out an ordinary class demostration. He passed an electric current trough a copper wire wich was joined to a voltaic cell. Amongst the apparatuses on his demostration bench there happened to be a magnetic needle and Oersted noticed that when his hand holding the wire moved near the needle the latter was deflected. With a quick jump of imagination he desconnected the ends of the wwire and connected them to the oposite ends of the cell and found that the needle was deflected in the  opposite direction. Ostered had discovered electromagnetism.

Serendipity is the art of looking for one thing but finding, quite by chance, something different. An american inventor, charles goodyear was trying to make rubber useful. In its natural form, the substance became soft and sticky on cold days. Goodyear heated rubber with sulphur, hopping to make a mixture that would remain dry and flexible at all reasonable temperatures. Success eluded him until, in 1839, he accidentally spilled the mixture on a hot stove. He peeled it off and found he had created the flexible rubber he wanted. The extra heat of the stove had led to the discovery of vulcanizaction.

Alexander Fleming discovered penicillin in 1928 as a result of the chance contamination in his lab of a culture plate of bacteria, known as staphylococci, by spores of the mould penicillin notatum. This mould had a hyghly destructive effect and this fact led him to conduct a close study of the mould which he subsequently called penicillin. Fleming made some discoveries regarding its action, but it was ten years later that other investigators succeeded in purifying the active substance and demostrating its remarkable curative properties.

Michael Faraday was a physicist and chemist. He discovered the principles of electromagnetic induction in 1831, demostrating that an electric current can be used as a source of mechanical power. Two years later he established the identity off the different forms of electricity, Faraday’s electromechanical experiments included the discovery of Faraday’s Laws of electrolyses, the effect of magnetism on polarized light and the phenomena of diamagnetism. His chemical studies included the investigation of chlorine, the liquification of several gases, steel alloys, and the manufacture of optical glass.

Robert watson. From 1915 onward he worked on the idea that the reflection of radio waves could be used to locate other objects beside layers of the atmosphere as had been done by Edward Appleton. He led the team which, in 1935, gave the first practical demostration of the radiolocation of aircraft by using the method now known as radar. It consisted in using short-wave radio to send out impulses which were reflected back from any object hit and the exact position plotted. The development of radar has been an invaluable aid for aerial and marine navegation.
