Jean Picard

Jean Picard

Birthday of the day: Jean Picard; Jean-Felix Picard (July 21, 1620 – July 12, 1682) was a French astronomer and priest born in La Flèche, where he studied at the Jesuit Collège Royal Henry-Le-Grand. He was the first person to measure the size of the Earth to a reasonable degree of accuracy in a survey conducted in 1669–70, for which he is honored with a pyramid at Juvisy-sur-Orge. Guided by Maurolycus’s methodology and Snellius’s mathematics for doing so, Picard achieved this by measuring one degree of latitude along the Paris Meridian using triangulation along thirteen triangles stretching from Paris to the clocktower of Sourdon, near Amiens. His measurements produced a result of 110.46 km for one degree of latitude, which gives a corresponding terrestrial radius of 6328.9 km. The polar radius has now been measured at just over 6357 km. This was an error only 0.44% less than the modern value. This was another example of advances in astronomy and its tools making possible advances in cartography. Picard was the first to attach a telescope with crosswires (developed by William Gascoigne) to a quadrant, and one of the first to use a micrometer screw on his instruments. The quadrant he used to determine the size of the Earth had a radius of 38 inches and was graduated to quarter-minutes. The sextant he used to find the meridian had a radius of six feet, and was equipped with a micrometer to enable minute adjustments. These equipment improvements made the margin of error only ten seconds, as opposed to Tycho Brahe’s four minutes of error. This made his measurements 24 times more accurate. Isaac Newton was to use this value in his theory of universal gravitation.

Joke of the day: Mr. Johnson was overweight, so his doctor put him on a diet. He said, ‘I want you to eat regularly for two days, then skip a day, and repeat this procedure for two weeks. The next time I see you, you should have lost at least five pounds.’ When Mr. Johnson returned, he shocked the doctor by having dropped almost twenty pounds. ‘Why, that’s amazing!’ the doctor told him. ‘You did this just by following my instructions?’ The slimmed down Mr. Johnson nodded. ‘I’ll tell you, though, I though I was going to drop dead that third day.’ ‘From hunger, you mean.’ ‘No’, replied Mr. Johnson, ‘from skipping.’

Thought of the day: There is no wealth like knowledge, no poverty like ignorance.
