ABSTRACTION: Simplifying the complexities of the real world by ignoring (hopefully) unimportant details while doing economic analysis. Abstraction is often criticized because it's, well, it's JUST NOT REALISTIC. However, when done correctly (ignoring things that JUST DON'T MATTER), then the pursuit of knowledge is greatly enhanced by abstraction. For example, when travelling cross country along a high-speed interstate highway, a paper road map is a handy tool. It shows towns and cities along the way, the major intersections, rest stop locations, and other important points of interest. However, it ignores unimportant details. It doesn't realistically show the location of every tree, bush, or blade of grass. Why bother? This information won't enhance your road trip.

COIN: A shiny metal disc, almost always authorized by a national government entity, with a raised impression of famous dead people on one side and a building or birds on the other that is used as money. U.S. coins are issued by the U.S. Treasury Department and come in denominations of pennies, nickels, dimes, quarters, half-dollars, and dollars. At one time, metal coins were comprised of valuable metal (that is, commodity money) in an amount equivalent to their face value. A dime had 10-cents worth of silver. A nickel had 5-cents worth of nickel. A penney had 1-cents worth of copper. Most modern coins, however, are fiat money, containing less valuable metal alloys. But they work just fine in vending machines. See also | money | cash | currency | commodity money | fiat money |
