There is a knock on the pearly...

There is a knock on the pearly gates. Saint Peter looks out, and a man is standing there. Saint Peter is about to begin his interview when the man disappears. A moment later there’s another knock. Saint Peter gets the door, sees the man, opens his mouth to speak, but the man disappears once again. “Hey, are you playing games with me?” Saint Peter calls after him, rather annoyed.
“No” the man’s distant voice replies anxiously.
“They are trying to resuscitate me.”

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)]
