A 6th-grade teacher posed the following problem to one of her arithmetic classes:
“A wealthy man dies and leaves ten million dollars.
One-fifth is to go to his wife, one-fifth is to go to his son, one-sixth to his butler, and the rest to charity.
Now, what does each get?”
After a very long silence in the classroom, one little boy raised his hand.
With complete sincerity in his voice, answered, “A lawyer!”

### Sir Nevill F. Mott

Died 8 Aug 1996 at age 90 (born 30 Sep 1905). Nevill Francis Mott was an English physicist whoshared(with PhilipW. Anderson and John H. Van Vleck of the U.S.) the 1977 Nobel Prize for Physics for his independent researches on the magnetic and electrical properties of amorphous semiconductors. Whereas the electric properties of crystals are described by the Band Theory - which compares the conductivity of metals, semiconductors, and insulators - a famous exception is provided by nickel oxide. According to band theory, nickel oxide ought to be a metallic conductor but in reality is an insulator. Mott refined the theory to include electron-electron interaction and explained so-called Mott transitions, by which some metals become insulators as the electron density decreases by separating the atoms from each other in some convenient way.
