Document Summary
On april 11, 1846, michael faraday was scheduled to introduce sir charles wheatstone at a meeting of the royal society of london. Unfortunately, wheatstone had a bad case of stage fright and took off just before his lecture was to begin. As a result, faraday was forced to give an unprepared lecture to the royal society of london. Faraday always gave well- prepared lectures punctuated by spectacular demonstrations, but he was totally unprepared for wheatstone"s departure. As a result, faraday was forced to spend an unrehearsed hour speculating on the future. Faraday commented on an 1845 discovery he made concerning the change of polarization caused in light passing through heavy glass when exposed to external magnetic fields. He uncharacteristically speculated on the possible interrelationship between light and magnetism. Unfortunately, faraday did not possess the background or required talent in mathematics required to advance this idea. Besides, his time and energy were consumed by other interests.
