Absentee Slips

In the HR department in the large corporation where I work, I receive absentee slips for all the employees.
Over the years I’ve heard every excuse, but the other day I found one in my voicemail that I never heard before.
“I won’t be in today,” said my absent coworker. “I’ll call back later with an excuse.”

Blaise Pascal

Died 19 Aug 1662 at age 39 (born 19 Jun 1623). 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.
