A lawyer calls a plumber for help...

The plumber assesses the situation and says, "I can fix it today for $800."

The lawyer, surprised, asks, "How long will it take?" The plumber replies, "I'll need about an hour to get a part from the supply house and another hour to do the repair."

The lawyer, smirking, says, "Two hours for $800? That's $400 per hour! I'm a lawyer, and I charge $350 per hour!"

The plumber nods and says, "Yes, I understand. That's why I left my law practice."

Born 7 Dec 1910; died 4 Apr 1980 at age 69.American biophysicist who contributed most to the discovery of "delayed neutrons" - that uranium fission does not release all the neutrons it produces at one time, but some come off at measurably later times. Some are emitted seconds to minutes later. This is crucial in the operation of a fission reactor. In uranium-235 fission in a thermal reactor, the proportion of delayed neutrons is about 0.65 percent. If the reactivity stays below the proportion of delayed neutrons, the reactor can be controlled. The delayed neutrons modify the rate of fission sufficiently to give time for the insertion of control rods. Without the margin of safety provided by the delayed neutrons, nuclear reactors might not be practical at all.*
