Improvements in Hell

An engineer died and ended up in Hell. He was not pleased with the level of comfort in Hell, and began to redesign and build improvements. After awhile, they had toilets that flush, air conditioning, and escalators. Everyone grew very fond of him.
One day God called to Satan to mock him, "So, how's it going down there in Hell?"
Satan replied, "Hey, things are great. We've got air conditioning and flush toilets and escalators, and there's no telling what this engineer is going to come up with next." God was surprised, "What? You've got an engineer? That's a mistake. He should never have gotten down there in the first place. Send him back up here."
"No way," replied Satan. "I like having an engineer, and I'm keeping him."
God threatened, "Send him back up here now or I'll sue!"
Satan laughed and answered, "Yeah, right. And just where are YOU going to get a lawyer?"

Shin-ichiro Tomonaga

Died 8 Jul 1979 at age 73 (born 31 Mar 1906).Japanese physicist whosharedthe Nobel Prize for Physics in 1965 (with Richard P. Feynman and Julian S. Schwinger of the U.S.) for independently developing basic principles of quantum electrodynamics. He was one of the first to apply quantum theory to subatomic particles with very high energies. Tomonaga began with an analysis of intermediate coupling - the idea that interactions between two particles take place through the exchange of a third (virtual particle), like one ship affecting another by firing a cannonball. He used this concept to develop a quantum field theory (1941-43) that was consistent with the theory of special relativity. WW II delayed news of his work. Meanwhile, Feynman and Schwinger published their own independent solutions.
