### Jean-Charles-Athanase Peltier

Born 22 Feb 1785; died 27 Oct 1845 at age 60.French physicist who discovered the Peltier effect (1834), that at the junction of two dissimilar metals an electric current will produce heat or cold, depending on the direction of current flow. In 1812, Peltier received an inheritance sufficient to retire from clockmaking and pursue a diverse interest in phrenology, anatomy, microscopy and meteorology. Peltier made a thermoelectric thermoscope to measure temperature distribution along a series of thermocouple circuits, from which he discovered the Peltier effect. Lenz succeeded in freezing water by this method. Its importance was not fully recognized until the later thermodynamic work of Kelvin. The effect is now used in devices for measuring temperature and non-compressor cooling units.«[Image: Peltier's atmospheric electricity gauge.]

### Homework

A little boy was doing his math homework. He said to himself,
"Two plus five, that son of a bitch is seven. Three plus six, that son of a bitch is nine...."
His mother heard what he was saying and gasped, "What are you doing?"
The little boy answered, "I'm doing my math homework, Mum."
"And this is how your teacher taught you to do it?" the mother asked
"Yes," he answered.
Infuriated, the mother asked the teacher the next day, "What are you teaching my son in math?"
The teacher replied, "Right now, we are learning addition."
The mother asked, "And are you teaching them to say two plus two, that son of a bitch is four?"
After the teacher stopped laughing, she answered, "What I taught them was, two plus two, THE SUM OF WHICH, is four."
