Re: Is one side of a quarter 'heavier' than the other?

Well, I don't know specifically how we can find the difference in mass,
but here's a way to test it.

First, assume the the design on both sides of the quarter is cut to the
same depth everywhere, almost like a woodcut.  Next, place a piece of
graph paper on the quarter and rub it with a pencil to get a copy of the
image of both sides of the coin.  Then count the number of squares that
each image takes up.  The side with more image has more mass.

The next thing to do is actually flip a coin a couple hundred times to see
if this difference in mass affects the bias of the coin.  You should end
up with about half heads, half tails.  You need to flip it at least a
hundred times, if not more, though.

Remember, Science is COOL! --and math is the coolest part of it!
