Shirt Pocket

A businessman entered a tavern, sat down at the bar, and ordered a double martini on the rocks. After he finished the drink, he peeked inside his shirt pocket, then he ordered another double martini. After he finished that one, he again peeked inside his shirt pocket and ordered another double martini.
Finally, the bartender said, "Look, buddy, I'll bring ya' martinis all night long. But you gotta tell me why you look inside your shirt pocket before you order a refill."
The customer replied, "I'm peeking at a photo of my wife. When she starts to look good, then I know it's time to go home."

Gerard Henri de Vaucouleurs

Died 7 Oct 1995 at age 77 (born 25 Apr 1918).French-born U.S. astronomer whose pioneering studies of distant galaxies contributed to knowledge of the age and large-scale structure of the universe. He produced three Reference Catalogues of bright galaxies (1964, 1976, 1991). Each was a homogenization of data from widely different sources, so that the catalogues would not be merely finding lists or data collection lists, but astrophysically useful databases. Using data in the Reference Catalogues, he was able to develop new distance indicators and refine others. His unique philosophy on distance matters was "spreading the risks," that is, applying as many different and independent techniques as possible to check for scale and zero-point errors.
