Chapter 10: an Excellent Days Work

After the acute attack Faraday had in 1839 that made him suspend his research, he sank into a period of depression and self enforced isolation. He suffered from low nervous attacks and memory loss so bad he couldn't finish a scentence. His condition was unpredictable. Nobody knew if he would ever return to his lab.
His wife Sarah did all she could but most of the time she took him out of the house and walked around town and went to the zoo. Faraday stopped writing letters also claiming that it was too exhausting for him. In 1845, a young researcher named William Thompson questioned Faraday and backed him why he didn't have any equations among his electricity books. Thompson also said that electricity or magnetism should have an effect on the travel of light. On august 30,1845, Faraday returned to his lab to redo an experiment he failed at nearly a decade ago to prove what the young Thompson said...
He did this by using polarized light and reflecting the glow of an oil lamp off an upright pane of glass. He then rotated the lenses until the lamps image was extinguishable. He then applied electricity to see if he could get a blackout image. In his first set of trials he disproved it but then he shifted to magnetism hoping for a different result and he succeeded. He was able to connect light and magnetism. It was called magnetism-diamagnetism.
