Each evening bird-lover Tom st...

Each evening bird-lover Tom stood in his backyard, hooting like an owl. One night, an owl called back to him. For a year, the man and his feathered friend hooted back and forth. He even kept a log of the "conversation."
Just as he thought he was on the verge of a breakthrough in interspecies communication, his wife had a chat with her next-door neighbor.
"My husband spends his nights... calling out to owls," she said.
"That's odd," the neighbor replied. "So does my husband."

Stephanie Kwolek

Born 31 Jul 1923; died 18 Jun 2014 at age 90. 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).
