Speeding Ticket

Cop pulls over a car with a couple in it.

"What's the problem officer?"

"Sir, you were going 68 in a 50-zone."

"What, that's ridiculous! I did no such thing!"

"Sir, I caught you with my radar gun, and it's always accurate, but I’ll give you some leeway and reduce it to 62.

"Well, not this time, asshole. I know I was doing 54! I'll take it to court, you son of a bitch!" The cop hands the man the ticket, and he rips it up.

"Sir, I'm going to have to insist you calm down, or I'll put you under arrest."

Suddenly, the wife interjects, "Mister, I wouldn't push it. There's no use arguing with him when he's drunk."

Charles Proteus Steinmetz

Born 9 Apr 1865; died 26 Oct 1923 at age 58. German-American electrical engineer and inventor whose theories and mathematical analysis of alternating current systems helped establish them as the preferred form of electrical energy in the United States, and throughout the world. In 1893, Steinmetz joined the newly organized General Electric Company where he was an engineer then consultant until his death. His early research on hysteresis (loss of power due to magnetic resistance) led him to study alternating current, which could eliminate hysteresis loss in motors. He did extensive new work on the theory of a.c. for electrical engineers to use. His last research was on lightning, and its threat to the new AC power lines. He was responsible for the expansion of the electric power industry in the U.S.
