A man is dining in a fancy restaurant, and there is a gorgeous redhead sitting at the next table. He had been checking her out since he sat down, but lacked the nerve to talk with her.
Suddenly she sneezes and her glass eye comes flying out of its socket towards the man. He reflexively reaches out, grabs it out of the air, and hands it back.
"Oh my, I am so sorry," the woman says as she pops her eye back in place. "Let me buy you dessert to make it up to you."
They enjoy a wonderful dessert together, and afterwards, the woman invites him to the theater followed by drinks. After paying for everything, she asks him if he would like to come to her place for a nightcap...and stay for breakfast the next morning.

Saul Dushman

Born 12 Jul 1883; died 7 Jul 1954 at age 70. Russian-American physical chemist, a world leader in vacuum science and technology, a GE assistant director of research and author of several standard scientific textbooks. One example is Scientific Foundations of Vacuum Technique (1922). It is very readable and he gets to the hows and whys things work the way they do. One of the true classics, it was completely revised in 1961 by his colleague James Lafferty. Using a formula he derived, Dushman calculated the conductances for cylindrical tubes based on their measured dimensions and produced the table which he included in the book that is still used to design a vacuum system.
