Every Friday after work, a mat...

Every Friday after work, a mathematician goes down to the Ice Cream Parlor, sits in the second-to-last seat, turns to the last seat, which is empty, and asks a girl, who isn't there, if he can buy her an ice cream cone.
The owner, who is used to the weird, local university types, always shrugs but keeps quiet. But when Valentine's Day arrives, and the mathematician makes a particularly heart wrenching plea into empty space, curiosity gets the better of him, and he says, "I apologize for my stupid questions, but surely you know there is never a woman sitting in that last stool, man. Why do you persist in talking to empty space?"
The mathematician replies, "Well, according to quantum physics, empty space is never truly empty. Virtual particles come into existence and vanish all the time. You never know when the proper wave function will collapse and a girl might suddenly appear there."
The owner raises his eyebrows. "Really? Interesting. But couldn't you just ask one of the girls who comes here every Friday if you could buy HER a cone? You never know... she might say yes."
The mathematician laughs. "Yeah, right. How likely is THAT to happen?"

Cray supercomputer

In 1977, the first Freon-cooled Cray-1 supercomputer, costing $19,000,000, was shipped to Los Alamos Laboratories, NM, and was used to help the defense industry create sophisticated weapons systems. This system had a peak performance of 133 megaflops and used the newest technology, integrated circuits and vector register technology. The Cray-1 looked like no other computer before or since. It was a cylindrical machine 7 feet tall and 9 feet in diameter, weighed 30 tons and required its own electrical substation to provide it with power (an electric bill around $35,000/month). The inventor, Seymour Cray, died 5 Oct 1996 in an auto accident. His innovations included vector register technology, cooling technologies, and magnetic amplifiers.
