As a sergeant in a parachute regiment I took part in several night time exercises. Once, I was seated next to a Lieutenant fresh from Jump School.He was quiet sad looked a bit pale so I struck up a conversation.
"Scared, Lieutenant?", I asked.
He replied, "No, just a bit apprehensive."
I asked, "What's the difference?"
He replied, "That means I'm scared with a university education."
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. |
