Seven New York City bartenders...

Seven New York City bartenders were asked if they could nail a woman's personality based on what she drinks. Though interviewed separately, they concurred on almost all counts. The results:
Drink: Beer
Personality: Casual, low-maintenance; down to earth.
Your Approach: Challenge her to a game of pool.
Drink: Blender Drinks
Personality: Flaky, whiny, annoying; a pain in the buttocks.
Your Approach: Avoid her, unless you want to be her cabin boy.
Drink: Mixed Drinks
Personality: Older, more refined, high maintenance, has very picky taste; knows exactly what she wants.
Your Approach: You won't have to approach her,> if she is interested, she'll send YOU a drink.
Drink: Wine - (does not include White Zinfandel, see below)
Personality: Conservative and classy; sophisticated yet giggles.
Your Approach: Tell her you love to travel and spend quiet evenings with friends.
Drink: White Zinfandel
Personality: Easy; thinks she is classy and sophisticated, actually has no clue.
Your approach: Make her feel smarter than she is.... this should be an easy target.
Drink: Shots
Personality: Likes to hang with frat-boy pals and looking to get totally drunk...... and naked.
Your Approach: Easiest hit in the joint. You have been blessed this evening. Nothing to do but wait. However, be careful not to make her mad!
Then there is the MALE addendum. The deal with guys is, as always, very simple and clear cut:
Domestic Beer: He's poor and wants to get laid.
Imported Beer: He likes good beer and wants to get laid.
Wine: He's hoping that the wine thing will give him a sophisticated image to help him get laid.
Whiskey: He doesn't give a hoot about anything but getting laid.
Tequila: He is thinking he has a chance with the toothless waitress.
White Zinfandel: He's gay.

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.
