One day in class, the teacher...
One day in class, the teacher brought a bag full of fruit and said, "Now class, I'm going to reach into the bag and describe a piece of fruit and you tell me which fruit I'm talking about. Alright, the first one is round, plump, and red. Little Johnny raised his hand high but the teacher ignored him and picked Deborah who promptly answered, "Apple." The teacher replied, "No Deborah, it's a beet, but I like your thinking. Now the second one is soft, fuzzy and colored red and brown." Johnny is hopping up and down in his seat trying to get the teacher to call on him but she calls on Billy. "Is it a peach?" Billy asks. "No, it's a potato, but I like your thinking," the teacher replies. "Okay the next one is long, yellow, and fairly hard." Johnny is about to explode as he waves his hand frantically but the teacher calls on Sally who say, "A banana." The teacher responds, "No, it's a squash, but I like your thinking." Johnny is irritated now so he speaks up loudly, "Hey, I've got one for you teacher. Let me put my hand in my pocket. Okay, I've got it. It's round, hard, and it's got a head on it." "Johnny!" she cries, "That's disgusting!" "Nope," answers Johnny, "It's a quarter, but I like your thinking!"

Richard P. FeynmanDied 15 Feb 1988 at age 69 (born 11 May 1918). Richard Philips Feynman was an American theoretical physicist who was probably the most brilliant, influential, and iconoclastic figure in his field in the post-WW II era. By age 15, he had mastered calculus. He took every physics course at MIT. His lifelong interest was in subatomic physics. In 1942, he went to Los Alamos where Hans Bethe made the 24 year old Feynman a group leader in the theoretical division, to work on estimating how much uranium would be needed to achieve critical mass for the Manhattan (atomic bomb) Project. After the war, he developed Feynman Diagrams, a simple notation to describe the complex behavior of subatomic particles. In 1965, he shared (with Julian Schwinger and Shin-ichiro Tomonaga) the Nobel Prize in Physics for work in quantum electrodynamics. |
