James McKeen Cattell

Born 25 May 1860; died 20 Jan 1944 at age 83. American psychologist who had a talent in mathematics from a young age, and accordingly applied objective, quantitative methods with his career in experimental psychology. As a university professor, he was the first in America to teach a course in statistical analysis. From 1890, he termed his investigations “mental testing,” with such goals as measuring the amount of pressure required to produce pain, or reaction time to sounds. He developed the order of merit ranking method. Fields in which he applied psychology were broad, including education, business, industry, and advertising. The ideas in Galton's eugenics theory also interested him, and he did support such concepts as sterilization of persons of lower intelligence. He originated professional directories, published scientific periodicals and founded the Science Press (1923).«

An Irishman is walking along the beach one day, and he sees a bottle laying in the sand. He picks it up and starts to brush it off, and out pops a genie.
The genie says, "Since you have freed me from the bottle, I will grant you three wishes."
The Irishman thinks for a moment and says, "I'm feeling a might thirsty, I think I'll be wishing for a pint of stout."
POOF! There is a pint of stout in his hand. He drinks it down, and starts to throw the bottle, when the genie says, "I'd look at that bottle again before I threw it if I were you." So he looks at the bottle, and it is magicaly filling back up with stout. The genie told him, "That is a magic bottle, and it will always fill back up after you finish it." The genie then asked, "What other two wishes can I grant for you?"
The Irishman looks at the bottle in his hand and says, "I'll be taking two more of these."
