A man and his young wife were...
A man and his young wife were in divorce court, but the custody of their children posed a problem.
The mother leaped to her feet and protested to the judge that since she brought the children into this world, she should retain custody of them.

After a long silence, the man slowly rose from his chair and replied...
"Your Honor, when I put a dollar in a vending machine and a Coke comes out, does the Coke belong to me or the machine?"

Sir Charles WheatstoneBorn 6 Feb 1802; died 19 Oct 1875 at age 73.English physicist who popularized the Wheatstone bridge, a device that accurately measured electrical resistance and became widely used in laboratories. He didn't actually invent the “Wheatstone Bridge”. His contemporary, Samuel Hunter Christie, came up with the idea of the bridge circuit, but Wheatstone set the precedent for using it in the way in which it has been most commonly used. Over time, the device became associated with him and took on his name. He did, however, invent the concertina (1829), the stereoscope (1838), and an early form of the telegraph. He also developed a chronoscope (1842) to determine the velocity of projectiles at an English gunnery. |
