Saint George and the Dragon

April 23rd is St. George’s Day, named after St. George, the patron saint of England.

A weary traveler in 18th century England, hungry and tired, approached a roadside inn with a sign that read: "Saint George and the Dragon."

He knocked on the door. The innkeeper's wife poked her head out of a window.

"Any chance for a bite to eat?" he inquired.

The woman eyed his ragged, filthy clothes and yelled, "No!"

"May I have a pint of ale?"

"No!" she yelled back.

"Can I at least rest in your stable?"

"No!" she yelled once more.

The traveler tried again, "Could I kindly...?"

"What is it now?" the woman snapped, cutting him off.

"Would it be possible," he asked, "to have a chat with George?"

Sir George Porter

Born 6 Dec 1920; died 31 Aug 2002 at age 81. English chemist, who was awarded a share of the 1967 Nobel Prize for Chemistry, with Englishman Ronald Norrish and German Manfred Eigen, "for their studies of extremely fast chemical reactions, effected by disturbing the equlibrium by means of very short pulses of energy." Porter showed how the flash-photolysis method - a technique for observing the intermediate stages of very fast chemical reactions - can be extended and applied to many diverse problems of physics, chemistry and biology. An example is the examination of photosynthesis. He extended these techniques into the nanosecond and picosecond regions. Porter also made contributions to other techniques, particularly that of radical trapping and matrix stabilisation.«
