Double Martini

A businessman enters a tavern, sits down at the bar, and orders a double martini on the rocks.
After he finishes the drink, he peeks inside his shirt pocket, then orders the bartender to prepare another double martini.
After he finishes that it, he again peeks inside his shirt pocket and orders the bartender to bring another double martini. The bartender says, "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 replies, "I'm peeking at a photo of my wife.
When she starts to look good, I know it's time to go home."

Rudolf Wolf

Died 6 Dec 1893 at age 77 (born 7 Jul 1816).Swiss astronomer and astronomical historian. Wolf's main contribution was the discovery of the 11 year sunspot cycle and he was the codiscoverer of its connection with geomagnetic activity on Earth. In 1849 he devised a system now known as Wolf's sunspot numbers. This system is still in use for studying solar activity by counting sunspots and sunspot groups. In mathematics, Wolf wrote on prime number theory and geometry, then later on probability and statistics - a long paper discussed Buffon's needle experiment. He estimated πby Monte Carlo methods.
