### The Sparrow

Once upon a time there was a non-conforming sparrow who decided not to fly south for the winter. However, soon the weather turned so cold that he reluctantly decided to fly south. In a short time ice began to form on his wings and he fell to Earth in a barnyard, nearly frozen solid. A cow passed by where he had fallen, and crapped on the little sparrow.The sparrow thought it was the end, but the manure warmed him and defrosted his wings!
Warm and happy, able to breath, he started to sing.
Just then a large cat came by, and hearing the chirping he investigated the sounds. The cat cleared away the manure, found the chirping bird, and promptly ate him.
The Moral of the Story:
Everyone who craps on you is not necessarily your enemy
Everyone who gets you out of crap is not necessarily your friend.
And if you're warm and happy in a pile of crap, you might just want to keep your mouth shut.

### 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.
