Georg von Peurbach

Died 8 Apr 1461 at age 37 (born 30 May 1423).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.]

An English teacher reminds her...

An English teacher reminds her students of the written test in her class tomorrow:
"Now, I don't want anyone to miss this important finals exam! I will not tolerate any excuse whatsoever for your absence--unless of course you had to go to the hospital because of a serious injury, or someone died in your immediate family."
Just after she spoke, a wise ass in the back of the class exclaims: "Well, what if I were to tell you that I didn't show up for the test because I experienced complete and utter sexual exhaustion?"
The students in the class try to suppress their snickers and muffled laughter.
The teacher looks sympathetically towards the young man, smiles slyly and states: "Well, then...you'll have to write with your other hand".
