AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE: A scientific society whose main mission is to advance science and innovation throughout the world. The American Association for the Advancement of Science (AAAS for short) publishes one of the most respected scientific magazines called Science. The association and magazine have nearly 140,000 individual and institutional subscribers, plus 272 affiliated organizations in more than 130 countries, serving a total of 10 million individuals. The American Association for the Advancement of Science was founded in 1848 to represent all disciplines of science and to support scientific exchange and discussion of science and society issues.

                           POINT ELASTICITY: The relative responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve. Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) calculate point elasticity by using derivatives. Derivatives are calculus talk for infinitesimally small changes. The formula for calculating point elasticity using calculus is given as:The symbol that looks like a backward six (∂) is the mathematical notation for a derivative, or infinitesimally small change. The first term on the right-hand side of this formula is the percentage change in variable B and the second term is the percentage change in variable A.Unsophisticated folks can also calculate point elasticity without the use of sophisticated calculus. This is done with the midpoint elasticity formula, presented here: midpoint
elasticity | = | (B2 - B1)
(B2 + B1)/2 | ÷ | (A2 - A1)
(A2 + A1)/2 |
The first term on the right-hand side of the equation is the percentage change in variable B. The second term is the percentage change in variable A. The individual items are interpreted as this: A1 is the initial value of A before any changes, A2 is the ending value after A changes, B1 is the initial value of B before any changes, and B2 is the ending value after B changes.This midpoint elasticity formula actually calculates the average or arc elasticity of the entire line segment. However, it also calculates the point elasticity for the midpoint of a line segment.
