Jim was a just out of boot cam...

Jim was a just out of boot camp, and was on his first ship. About two hours out of port, he began to get a bit ill from the motion of the ship. He approached an ensign, also just out of training and on his first cruise.
He saluted and said, "Excuse me sir, I am feeling seasick, and I wondered if I may have permission to go downstairs to the dispensary."
The ensign returned his salute and replied, "Sailor, you are in the Navy now. You don't go downstairs, you go below! There is no dispensary on this ship, there is sickbay. Not only that, that is not the floor, it is a deck; that is not the ceiling, it is the overhead; that is not a pillar, it is a stanchion; that is not a water fountain, it is a scuttlebutt. If I ever hear you using civilian words instead of Naval jargon, I will throw you out of that little round window over there."

Arago announces electromagnetism

In 1820, Francois Arago announced that a copper wire between the poles of a voltaic cell, could laterally attract iron filings to itself (Ann. de Chim. et de Physique., xv. p.93). His discovery came in the same year that Oersted discovered that an electric current flowing in a wire would deflect a neighbouring compass needle. Arago in the same publication described how he had successfully succeeded in causing permanent magnetism in steel needles laid at right angles to the copper wire. Arago and André-Marie Ampère, discussed and experimented with forming the copper wire into a helix to intensify the magnetizing action. However, it was not until 1825 that the electromagnet in its familiar form was invented by William Sturgeon.«
