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."

Deuterium

In 1933, Ernest Rutherford suggested the names diplogen for the newly discovered heavy hydrogen isotope and diplon for its nucleus. He presented these ideas in the Discussion on Heavy Hydrogen at the Royal Society. For ordinary hydrogen, the lightest of the atoms, having a nuclues of a sole proton, he coined a related name: haplogen. (Greek: haploos, single; diploos, double.) In 1931, Harold Urey had discovered small quantities of atoms of heavy hydrogen wherever ordinary hydrogen occurred. The mass of its nucleus was double that of ordinary hydrogen. This hydrogen-2 is now called deuterium, as named by Urey (Greek: deuteros, second). Its nucleus, named a deuteron, has a neutron in addition to a proton.[ref: Proc. Roy. Soc. A, vol. 144 (1934)]
