Niels Bohr

Died 18 Nov 1962 at age 77 (born 7 Oct 1885). Niels Henrik David Bohr was a Danish physicist who was thefirstto apply the quantum theory, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. For this work he received the Nobel Prize for Physics in 1922. He developed the so-called Bohr theory of the atom and liquid model of the nucleus. Bohr was of Jewish origin and when the Nazis occupied Denmark he escaped in 1943 to Sweden on a fishing boat. From there he was flown to England where he began to work on the project to make a nuclear fission bomb. After a few months he went with the British research team to Los Alamos in the USA where they continued work on the project.

Polishing Apples

A young man asked an old rich man how he made his money.
The old guy fingered his expensive wool vest and said, "Well, son, it was 1932. The depth of the Great Depression. I was down to my last nickel."
"I invested that nickel in an apple. I spent the entire day polishing the apple and, at the end of the day, I sold the apple for ten cents."
"The next morning, I invested those ten cents in two apples. I spent the entire day polishing them and sold them at 5:00 pm for 20 cents. I continued this system for a month, by the end of which I'd accumulated a fortune of $9.80."
"Then my wife's father died and left us two million dollars."
