I am a firm believer of Sturgeon's Law, which says that ninety percent of everything is garbage. I have no doubt that Sturgeon's Law applies to this very website. Had I any way to discern which of the above pages were indeed vapid trash, I would be pleased to promptly delete them; I welcome nominations.

Among the glories of mensuration in the United States is the following:

Feathers, and most other things, are weighed by the avoirdupois ounce, which is about 28.35 grams. However, gold and other precious metals are weighed by the troy ounce, which is about 31.10 grams. So the ounce of feathers weighs less than the ounce of gold.

Meanwhile, an avoirdupois pound is sixteen avoirdupois ounces, making the pound of feathers weigh about 453.59 grams. But a troy pound is only twelve troy ounces, which works out to about 373.24 grams. So the pound of feathers weighs more than the pound of gold.
