The bookie slowly counted out...

The bookie slowly counted out the money into the old lady's wrinkled hands.
"Lady," he said, "I just don't understand. However did you manage to pick the winner?"
The old lady patted her white locks in place. She looked a little bewildered. "Really," she said, "I don't know myself. I just stick a pin in the paper and, well, there it is."
The bookie took a deep breath. "That's all very well, lady," he cried. "But how on earth did you manage to pick four winners yesterday afternoon?"
"Oh," replied the old lady, "that was easy. I used a fork."

Giambatista Beccaria

Born 3 Oct 1716; died 27 May 1781 at age 64. Giambatista (orig. Francesco) Beccaria was an Italian physicist who spread knowledge of Benjamin Franklin's discoveries with electricity, which he extended with his own research. He designed an electrical thermometer and investigated the relative powers of parallel plate condensers (capacitors). He formed explanations for meteorological and geophysical phenomena in terms of “natural electricity.” With his students, he experimentally probed the atmosphere with metal poles, kites and rockets. He published his work in five books.
