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.]

Cotton Candy

So this old man is walking down the street in Brooklyn.

He sees a young boy sitting on the street in front of a candy shop, shoving sweets in his mouth as fast as possible.

The man walks up to the boy and says "You know son, it's really not healthy to eat all that candy."

The kid looks up at him and says, "You know my grandfather lived to be 97 years old."

The man replies "Oh and did he eat a lot of candy?" The kid looks at him and says "No, but he minded his own fucking business."
