Try To Get Some Rest

A man had been driving all night and by morning was still far from his destination. He decided to stop at the next city he came to, and park somewhere quiet so he could get an hour or two of sleep. As luck would have it, the quiet place he chose happened to be on one of the city's major jogging routes. No sooner had he settled back to snooze when there came a knocking on his window. He looked out and saw a jogger running in place.
"Yes?"
"Excuse me, sir," the jogger said, "do you have the time?" The man looked at the car clock and answered, "8:15". The jogger said thanks and left. The man settled back again, and was just dozing off when there was another knock on the window and another jogger.
"Excuse me, sir, do you have the time?"
"8:25!"
The jogger said thanks and left. Now the man could see other joggers passing by and he knew it was only a matter of time before another one disturbed him. To avoid the problem, he got out a pen and paper and put a sign in his window saying, "I do not know the time!" Once again he settled back to sleep. He was just dozing off when there was another knock on the window.
"Sir, sir? It's 8:45!."

Jean Picard

Born 21 Jul 1620; died 12 Jul 1682 at age 61. French astronomer, cartographer and hydraulic engineer who is regarded as the founder of modern astronomy in France. He introduced new methods, improved the old instruments, and added new devices, such as Huygens' pendulum clock to record times and time intervals. Picard was the first to put the telescope to use for the accurate measurement of small angles, making use of Gascoigne's micrometer. He devised a movable-wire micrometer to measure the diameters of celestial objects such as the Sun, Moon and planets. For land surveying and leveling, he designed instruments that incorporated the astronomical telescope. Picard was one of the first to apply scientific methods to the making of maps. Among his other skills were hydraulics; he solved the problem of supplying the fountains at Versailles with water. His most important work was the first measurement of the circumference of the earth. He used the method of Eratosthenes, but with greater accuracy. He greatly increased the accuracy of measurements of the Earth, using Snell's method of triangulation (Mesure de la Terre, 1671). This data was used by Newton in his gravitational theory. The concept behind neon signs began in 1675, when Picard observed a glow in a barometer.
