My wife and I went to the County Agricultural Show and one of the first exhibits we stopped at was the breeding bulls. We went up to the first pen and there was a sign attached that said:
THIS BULL MATED 50 TIMES LAST YEAR
My wife playfully nudged me in the ribs ..... Smiled and said, "He mated 50 times last year, that's almost once a week".
We walked to the second pen which had a sign attached that said:
THIS BULL MATED 150 TIMES LAST YEAR
My wife gave me a healthy jab and said, "WOW~~That's more than twice a week! .......... You could learn a lot from him".
We walked to the third pen and it had a sign attached that said:
THIS BULL MATED 365 TIMES LAST YEAR
My wife was so excited that her elbow nearly broke my ribs, and said,"That's once a day .. You could REALLY learn something from this one".
I looked at her and said, "Go over and ask him if it was with the same cow".
My condition has been upgraded from critical to stable and the doctors say I should eventually make a full recovery.

John William Draper

Died 4 Jan 1882 at age 70 (born 5 May 1811). English-American chemist who pioneered in photochemistry. He recognized that light initiated chemical reactions as molecules absorbed light energy. The Draper Point is the name given to the point at which all substances glow a dull red (about 525 degrees C.). He described the effect of rise in temperature as the addition of more and more of the visible light region produced a white glow (1847). His interest in spectroscopy and photography was applied to give the first astronomical photograph. Its subject was the moon (1840). He also studied photographs of the solar spectrum to show that contained both infrared and ultraviolet light. His photographs of persons include the oldest surviving photographic portrait (1840), and he was one of the first to produce microphotographs.
