A man sees a gorgeous and sexy woman standing alone at a bar. After tossing back a couple of shots he gets the nerve to approach her and says: "Hi, I was going to tell you a joke about my penis, but it's too long."
The woman looks at him for a moment and replies: "What a coincidence. I was going to tell you a joke about my ass, but you'll never get it."

Henry Moseley

Born 23 Nov 1887; died 10 Aug 1915 at age 27. Henry Gwyn-Jeffreys Mosely was an English physicist who experimentally demonstrated that the major properties of an element are determined by the atomic number, not by the atomic weight, and firmly established the relationship between atomic number and the charge of the atomic nucleus. He began his research under Ernest Rutherford while serving as lecturer at the Univ. of Manchester. Using X-ray photographic techniques, he determined a mathematical relation between the radiation wavelength and the atomic numbers of the emitting elements. Moseley obtained several quantitative relationships from which he predicted the existence of three missing elements (numbers 43, 61, and 75) in the periodic table, all of which were subsequently identified. Moseley was killed in action during WW I.
