El Número de Avogadro

1959. Una importante reunión de científicos de Harvard.

Un joven llamado Tom Lehrer, estudiante de esa prestigiosa universidad, ante el asombro de todos los presentes canta una canción. El asombro se convierte en risas. La letra de la canción no es otra cosa que todos los elementos uno detrás de otro (no en el orden creciente de número atómico, por supuesto).

There's antimony, arsenic, aluminum, selenium,
And hydrogen and oxygen and nitrogen and rhenium,
And nickel, neodymium, neptunium, germanium,
And iron, americium, ruthenium, uranium,
Europium, zirconium, lutetium, vanadium,
And lanthanum and osmium and astatine and radium,
And gold and protactinium and indium and gallium,
(gasp)
And iodine and thorium and thulium and thallium.

There's yttrium, ytterbium, actinium, rubidium,
And boron, gadolinium, niobium, iridium,
And strontium and silicon and silver and samarium,
And bismuth, bromine, lithium, beryllium, and barium.


Isn't that interesting?
(laughter)
I knew you would.
I hope you're all taking notes, because there's going to be a short quiz next period.

There's holmium and helium and hafnium and erbium,
And phosphorus and francium and fluorine and terbium,
And manganese and mercury, molybdenum, magnesium,
Dysprosium and scandium and cerium and cesium.
And lead, praseodymium, and platinum, plutonium,
Palladium, promethium, potassium, polonium,
And tantalum, technetium, titanium, tellurium,
(gasp)
And cadmium and calcium and chromium and curium.

There's sulfur, californium, and fermium, berkelium,
And also mendelevium, einsteinium, nobelium,
And argon, krypton, neon, radon, xenon, zinc, and rhodium,
And chlorine, carbon, cobalt, copper, tungsten, tin, and sodium.

These are the only ones of which the news has come to Ha'vard,
And there may be many others, but they haven't been discavard.
