An investment counselor decide...

An investment counselor decided to go out on her own. She was shrewd and diligent, so business kept coming in, and pretty soon she realized that she needed an in-house counsel. She began to interview young lawyers.
"As I'm sure you can understand," she started off with one of the first applicants, "in a business like this, our personal integrity must be beyond question." She leaned forward. "Mr. Peterson, are you an honest lawyer?"
"Honest?" replied the job prospect. "Let me tell you something about honest. Why, I'm so honest that my father lent me $15,000 for my education, and I paid back every penny the minute I tried my very first case."
"Impressive. And what sort of case was that?"
The lawyer squirmed in his seat and admitted, "He sued me for the money."

Robert Sanderson Mulliken

Born 7 Jun 1896; died 31 Oct 1986 at age 90. American chemist and physicist who received the 1966 Nobel Prize for Chemistry for “fundamental work concerning chemical bonds and the electronic structure of molecules.”In 1922, he first suggested a method of isotope separation by evaporative centrifuging. Thereafter, most of his research career was concerned with the interpretation of molecular spectra and with the application of quantum theory to the electronic states of molecules. With Friedrich Hund, he developed the molecular-orbital theory of chemical bonding, based on the idea that atomic orbitals of isolated atoms become molecular orbitals, extending over two or more atoms in the molecule. He also made major contributions to the theory and interpretation of molecular spectra.
