In Love

The pretty teacher was concerned with one of her eleven-year-old students. Taking him aside after class one day, she asked, "Little Johnny, why has your school work been so poor lately?"
"I'm in love," the boy replied.
Holding back an urge to smile, she asked, "With whom?"
"With YOU!" he said.
"But Johnny," she said gently, "don't you see how silly that is? It's true that I would like a husband of my own someday. But I don't want a child."
"Oh, don't worry," the boy said reassuringly, "I'll use a rubber!"

Robert L. Banks

Born 24 Nov 1921; died 3 Jan 1989 at age 67.American chemist who co-discovered crystalline polypropylene polymer, with J. Paul Hogan. They were assigned by Phillips Petroleum, in 1946, to research ways to take the natural gas products propylene and ethylene and turn them into useful gasoline components. On 5 Jun 1951, their experiments using catalysts yielded polypropylene - now used in fibers for rope, indoor-outdoor carpeting and plastics. Banks and Hogan also found how to make a new high-density polyethylene which was more heat resistant than the previously existing polyethylene. Further, their catalysts produced the new polyethylene at only a few hundred psi pressure instead of the existing free radical process which required pressures of up to 30,000 psi.«
