Little Johnny was eating breakfast one morning and got to thinking about things. “Mommy, mommy, why has daddy got so few hairs on his head?” he asked his mother.
“He thinks a lot,” replied his mother, pleased with herself for coming up with a good answer to her husband's baldness.
Or she was until Johnny thought for a second and asked, “So why do you have so much hair?”
Blaise PascalBorn 19 Jun 1623; died 19 Aug 1662 at age 39. French mathematician and physicist who was a child prodigy. He laid the foundation for the modern theory of probabilities. In hydrodynamics he formulated what came to be known as Pascal's law of pressure, and invented the syringe and hydraulic press. Pascal invented the first digital calculator to help his father with his work collecting taxes. He worked on it for three years (1642-45). The device, called the Pascaline, resembled a mechanical calculator of the 1940s. This, almost certainly, makes Pascal the second person to invent a mechanical calculator for Schickard had manufactured one in 1624. He died at the young age of 39 having been sickly and physically weak through life. Autopsy showed he had been born with a deformed skull. |
