Baseball boy

A little boy walked up to homeplate in an empty baseball field, with his bat and ball in hand.

As he threw the ball up in the air, he proclaimed, "I am the best ball player ever!" He swung with all his might, but missed.

He did the same thing and missed again.

He picked up the ball, tossed it up one more time, said "I am the best ball player in the world!" Then he swung and missed again.

"Wow!" he said. "What a pitcher!"

Donald R. Griffin

Died 7 Nov 2003 at age 88 (born 3 Aug 1915). Donald Redfield Griffin was an American biophysicist, known for his research in animal navigation, animal behaviour, and sensory biophysics. With Robert Galambos, he studied bat echolocation (1938), a term he coined (1944) for how the bat's ears replace eyes in flight guidance. Using specialized high-frequency sound equipment by G.W. Pierce, they found that bats in flight produced ultrasonic sounds used to avoid obstacles. In WW II, he used physiological principles to design such military equipment as cold-weather clothing and headphones. Griffin also worked extensively on bird navigation. In the late 1940s, he flew in a Piper Cub to observe the flight paths of gannets and gulls. In his career, he pioneered rigorous techniques to study animals in their natural environment.«
