Every time you switch on a light, start up a computer or turn on a television, you do it because of discoveries related to the work of Michael Faraday. In a swimming pool you will be guarded from disease because of liquid chlorine in the water: this is because Michael Faraday first liquefied chlorine. Faraday built the very first electric motor and later the first generator and transformer of electricity. But Michael Faraday also suffered from a disorder known as dyslexia. This meant that he had difficulty in learning to read or interpret words, letters, and other symbols. Faraday however, overcame this problem to become one of the greatest public lecturers in history.
