Along with "new math" and foreign languages that no one ever used. After all of that, we didn't know how to balance a checkbook.
Still would rather own the lesser weight Troy pound of gold, unless of course the feathers were from a Marilyn Monroe pin up postcard from 1954. Gold was at 34.25 oz in 1954 so multiply by 12 oz for a Troy pound and that would only be 423.00. I think in 1954 and beyond many men would have bid a lot more than 423.00 to own those feathers on the gorgeous Marilyn. Everything is relative, depending on many often changing factors and present conditions. Er, um what was the original question ....
Indeed. And a "pound" of feathers has more weight (and mass) than a pound of gold. Put a pound of something light on one side of a balance scale and a pound of something heavy (like gold) on the other and they'll balance. But evacuate the air and the lighter material will fall like a rock. This is because all of nature operates on all things at all times. When the weights exist in air held in place by earth's gravitational field bouyancy is imparted by that air. Larger objects have greater bouyancy hence you need a greater amount to make a pound. We know everything falls at the same acceleration (32 '/sec /sec) but a similar effect is seen when we drop a pound of gold and a pound of feathers.
Um, why is that? I bet you that if you poll an average person they have clue of the differences. I bet even amongst coin collect there is not uniform knowledge of the difference in the weight units. If you don't like the thread don't read it. Even though I knew the answer thoroughly I would never respond like you have. It was a fine thread @Dougmeister, and I bet you it did help many people.
