St. Peter and Satan were having an argument one day about baseball. Satan proposed a game to be played on neutral grounds between a select team from the heavenly host and his own hand-picked boys.
"Very well," said the gatekeeper of Heaven. "But you realize, I hope, that we've got all the good players and the best coaches."
"I know, and that's all right," Satan answered unperturbed. "We've got all the umpires."
Faraday discovers diamagnetismIn 1845, Michael Faraday, working in his laboratory at the Royal Institution, hung a piece of heavy glass between the poles of an electro-magnet and observed that the glass aligned itself across the lines of force of the magnet. He further experimented on many other substances, with similar results, a phenomena that he named diamagnetism. These investigations showed Faraday that magnetism was inherent within matter. This led to his lecture “Thoughts on Ray-vibrations”in April 1846, which he expanded in the following years into his field theory of electro-magnetism. This was the progenitor for mathematical descriptions formed by Thomson, and especially for the seminal work of James Clerk Maxwell.« |
