Wrong Way

As a senior citizen was driving down the freeway, his car phone rang.
Answering, he heard his wife’s voice urgently warning him.
“Herman, I just heard on the news that there’s a car going the wrong way on 280 interstate. Please be careful!”

“It’s not just one car,” said Herman. “It’s hundreds of them!”

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).
