Johann Salamo Christoph SchweiggerBorn 8 Apr 1779; died 6 Sep 1857 at age 78.German physicist who invented the galvanometer (1820), a device to measure the strength of an electric current. He developed the principle from Oersted's experiment (1819) which showed that current in a wire will deflect a compass needle. Schweigger realized that suggested a basic measuring instrument, since a stronger current would produce a larger deflection, and he increased the effect by winding the wire many times in a coil around the magnetic needle. He named this instrument a “galvanometer”in honour of Luigi Galvani, the professor who gave Volta the idea for the first battery. Thomas Seebeck (1770-1831) named the innovative coil, Schweigger's multiplier. It became the basis of moving coil instruments and loudspeakers.
That Darn Cat
A man who absolutely hated his wife's cat decided to get rid of him one day by driving him 20 blocks from his home and leaving him at the park.
As he was nearing home, the cat was walking up the driveway.
The next day, he decided to drive the cat 40 blocks away and try the same thing.
As we was driving back into his driveway, there was the cat! He kept taking the cat farther and farther away, but the darn cat would always beat him home.
At last, he decided to drive a few miles away, turn right, then left, past the bridge, then right again and another right and so on until he reached what he thought was a safe distance from his home and he left the cat there.
Hours later, the man calls home to his wife: "Jen, is the cat there?"
"Yes," the wife answers. "Why do you ask?"
Frustrated, the man answers: "Put that damn cat on the phone. I'm lost and I need directions!"
