Georg von Peurbach

Born 30 May 1423; died 8 Apr 1461 at age 37.Austrian mathematician and astronomer who promoted the use of Arabic numerals (introduced 250 years earlier in place of Roman numerals), especially in a table of sines he calculated with unprecedented accuracy. He died before this project was finished, and his pupil, Regiomontanus continued it until his own death. Peurbach was a follower of Ptolomy's astronomy. He insisted on the solid reality of the crystal spheres of the planets, going somewhat further than in Ptolomy's writings. He calculated tables of eclipses in Tabulae Ecclipsium, observed Halley's comet in Jun 1456 and the lunar eclipse of 3 Sep 1457 from a site near Vienna. Peurbach wrote on astronomy, his observations and devised astronomical instruments.[Image: from Epitome of the Almagest.]

Horse Pulls The Car


An out-of-towner drove his car into a ditch in a desolated area. Luckily, a local farmer came to help with his big strong horse named Buddy.
He hitched Buddy up to the car and yelled, "Pull, Nellie, pull." Buddy didn't move.
Then the farmer hollered, "Pull, Buster, pull." Buddy didn't respond.
Once more the farmer commanded, "Pull, Jennie, pull." Nothing.
Then the farmer nonchalantly said, "Pull, Buddy, pull." And the horse easily dragged the car out of the ditch.
The motorist was most appreciative and very curious. He asked the farmer why he called his horse by the wrong name three times.
The farmer said, "Oh, Buddy is blind, and if he thought he was the only one pulling, he wouldn't even try!"
