Stephanie Kwolek

Died 18 Jun 2014 at age 90 (born 31 Jul 1923). American chemist and inventor of Kevlar. Shortly after graduating with a bachelor's degree in chemistry (1946), she began a career at DuPont's textile fibers department in Buffalo, New York. Kwolek was assigned to search for a new, high-performance fiber that would be acid- and base-resistant and stable at high temperatures, suitable to replace steel in radial tyres. After extensive experimentation, she created a polymer solution which, when spun into a fibre, was five times stronger than steel and had half the density of fiberglass. It was named Kevlar. Today, this fibre is used to make bullet-proof jackets military helmets, aircraft parts, inflatable boats, gloves, rope, and building materials. Kwolek never pursued a Ph.D. degree. She was the fourth woman inducted into the National Inventors Hall of Fame (1995).

A blonde was hard up for money...

A blonde was hard up for money, so she walked around her neighborhood, trying to find a job.
She met a nice man who said he would give her work. All she had to do was paint his porch white. He gave her a bucket of paint and left.
He walked into his house, laughing. He told his brunette wife what he had done. "Frank, our porch covers half of the house! You're so mean." his wife replied. Three hours later, the blonde went in the house, and gave the bucket of white paint back to the man.
The astonished man handed her a $100 bill, and asked how she finished it so quickly.
"It takes time, but it was easy." was her reply. "Oh, and it's a Ferrari, not a Porsche."
