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.

Richard Brooke Roberts

Born 7 Dec 1910; died 4 Apr 1980 at age 69.American biophysicist who contributed most to the discovery of "delayed neutrons" - that uranium fission does not release all the neutrons it produces at one time, but some come off at measurably later times. Some are emitted seconds to minutes later. This is crucial in the operation of a fission reactor. In uranium-235 fission in a thermal reactor, the proportion of delayed neutrons is about 0.65 percent. If the reactivity stays below the proportion of delayed neutrons, the reactor can be controlled. The delayed neutrons modify the rate of fission sufficiently to give time for the insertion of control rods. Without the margin of safety provided by the delayed neutrons, nuclear reactors might not be practical at all.*
