Tour Bus Driver

A tour bus driver is driving with a bus full of old aged pensioners when he is tapped on his shoulder by a little old lady.
She offers him a handful of peanuts, which he gratefully munches up.
After about 15 minutes, she taps him on the shoulder again and she hands the driver another handful of peanuts.
When she is about to hand him another batch again, he asks her "Why don't you eat the peanuts?"
"We can't chew them because we have no teeth", she replied.
"We just love the chocolate around them."

Sir Ambrose Fleming

Born 29 Nov 1849; died 18 Apr 1945 at age 95. John Ambrose Fleming was an English electrical engineer who invented, and coined the name for, the first thermonic valve (also known as a vacuum tube). It was a diode with two electrodes, that acted as a rectifier, restricting current to flow in only one direction in a circuit (patented 1904). It made use of the Edison effect— the emission of electrons from a heated metal surface. By sealing a heated filament in a glass envelope containing a vacuum, the internal movement of electrons was not obstructed by gas molecules. The second electron at high positive voltage attracted the electrons released from the surface of the first, heated, electrode. It was applied the device in circuits for the nacent telecommunications industry. His name is remembered in the Fleming “Left Hand Rule” mnemonicfor relating the directions of motion, current and magnetic field for a motor.«
