Donald is walking out of the White House and heading toward his limo, when a possible assassin steps forward and aims a gun.
A secret service agent, new on the job, shouts 'Mickey Mouse!'
This startles the would-be assassin and he is captured.
Later, the secret service agent's supervisor takes him aside and asks, 'What in the hell made you shout Mickey Mouse?'
Blushing, the agent replies, 'I got nervous. I meant to shout 'Donald, duck!'
Georg von PeurbachBorn 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.] |
