Would you watch my car?

A tourist climbed out of his car in downtown Washington, D.C. He said to a man standing near the curb, "Listen, I'm going to be only a couple of minutes. Would you watch my car while I run into this store?"

"What?" the man huffed. "Do you realize that I am a member of the United States Senate?"

"Well no," the tourist said, "I didn't realize that. But it's all right. I'll trust you anyway."

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.
