[00:00.000] 作曲 : Lehrer, Sullivan[00:16.145] Now, if i may digress momentarily from the main stream of this evenings symposium,[00:24.356] I'd like to sing a song which is completely pointless[00:28.827] but which is something i picked up during my career as a scientist.[00:33.429] this may prove useful to somebody some day perhaps,[00:36.126] In a somewhat bizarre set of circumstances.[00:38.897] It's simply the names of the chemical elements set to a possibly recognizable tune.[00:52.889] There's antimony, arsenic, aluminum, selenium,[00:54.797] And hydrogen and oxygen and nitrogen and rhenium,[00:56.687] And nickel, neodymium, neptunium, germanium,[00:58.563] And iron, americium, ruthenium, uranium,[01:00.484] Europium, zirconium, lutetium, vanadium,[01:02.422] And lanthanum and osmium and astatine and radium,[01:04.439] And gold and protactinium and indium and gallium,[01:07.395] And iodine and thorium and thulium and thallium.[01:11.304] There's yttrium, ytterbium, actinium, rubidium,[01:13.336] And boron, gadolinium, niobium, iridium,[01:15.178] And strontium and silicon and silver and samarium,[01:17.238] And bismuth, bromine, lithium, beryllium, and barium.[01:22.959] Isn't that interesting?[01:26.778] I knew you would.[01:29.299] I hope you're all taking notes, because there's going to be a short quiz next period.[01:34.071] There's holmium and helium and hafnium and erbium,[01:35.988] And phosphorus and francium and fluorine and terbium,[01:37.857] And manganese and mercury, molybdenum, magnesium,[01:39.769] Dysprosium and scandium and cerium and cesium.[01:41.709] And lead, praseodymium, and platinum, plutonium,[01:43.620] Palladium, promethium, potassium, polonium,[01:45.419] And tantalum, technetium, titanium, tellurium,[01:48.383] And cadmium and calcium and chromium and curium.[01:52.238] There's sulfur, californium, and fermium, berkelium,[01:54.345] And also mendelevium, einsteinium, nobelium,[01:56.304] And argon, krypton, neon, radon, xenon, zinc, and rhodium,[01:58.305] And chlorine, carbon, cobalt, copper, tungsten, tin, and sodium.[02:02.622] These are the only ones of which the news has come to ha'vard,[02:06.486] And there may be many others, but they haven't been discavard.
