COMMODITY EXCHANGE: A financial market that trades the ownership of various commodities, such as wheat, corn, cotton, sugar, crude oil, natural gas, gold, silver, and aluminum. The two biggest commodity exchanges in good old U. S. of A. are the Chicago Board of Trade and the Chicago Mercantile Exchange. Unlike, let's say a grocery store where commodities physically trade hands, commodity exchanges trade only legal ownership. This is much like a stock market, which trades the ownership of a corporation, but leaves the factory at home. Commodity markets offer two basic sorts of trading -- spot (immediate delivery of a commodity) and futures (delivery of a commodity at a future date).

HYPOTHESIS

A reasonable proposition about the workings of the world that is inspired or implied by a theory and which may or may not be true. A hypothesis is essentially a prediction made by a theory that can be compared with observations in the real world. A hypothesis usually takes the form: "If A, then also B." The essence of the scientific method is to test, or verify, hypotheses against real world data. If supported by data over and over again, a hypothesis becomes a principle.
