An old lady, who lived on the third floor of a boardinghouse, broke her leg.
As the doctor put a cast on it, he warned her not to climb any stairs.
Several weeks later, the doctor took off the cast.
"Can I climb stairs now?" asked the little old lady.
"Yes," the doctor replied.
"Thank goodness!" she said. "I'm sick and tired of shimmying up and down that drainpipe!"

John A. Pople

Born 31 Oct 1925; died 15 Mar 2004 at age 78.British mathematician and chemist who shared (with Walter Kohn) the 1998 Nobel Prize in Chemistry for his work on computational methodology to study the quantum mechanics of molecules, their properties and how they act together in chemical reactions. Using Schrödinger's fundamental laws of quantum mechanics, he developed a computer program which, when provided with particulars of a molecule or a chemical reaction, outputs a description of the properties of that molecule or how a chemical reaction may take place - often used to illustrate or explain the results of different kinds of experiment. Pople provided his GAUSSIAN computer program to researchers (first published in 1970). Further developed, it is now used by thousands of chemists the world over.
