  • electrified fence — a barrier that uses electric shocks to deter animals or people from crossing a boundary
  • electrocardiogram — A record or display of a person’s heartbeat produced by electrocardiography.
  • electrodeposition — The deposition of a metal on a cathode during electrolysis; used as a method of purification.
  • emergency landing — an occasion when a place is forced to land: for example, because of a mechanical fault, bad weather, terrorism, etc.
  • epicycloidal gear — a gear of an epicyclic train
  • esprit d'escalier — clever repartee one thinks of too late
  • exception handler — Special code which is called when an exception occurs during the execution of a program. If the programmer does not provide a handler for a given exception, a built-in system exception handler will usually be called resulting in abortion of the program run and some kind of error indication being returned to the user. Examples of exception handler mechanisms are Unix's signal calls and Lisp's catch and throw.

  • field sales force — a team of people selling a product or service in the field as opposed to over the telephone, etc
  • financial adviser — A financial adviser is someone whose job it is to advise people about financial products and services.
  • first-aid classes — classes which teach people how to give immediate medical help in an emergency
  • first-order logic — (language, logic)   The language describing the truth of mathematical formulas. Formulas describe properties of terms and have a truth value. The following are atomic formulas: True False p(t1,..tn) where t1,..,tn are terms and p is a predicate. If F1, F2 and F3 are formulas and v is a variable then the following are compound formulas: The "order" of a logic specifies what entities "For all" and "Exists" may quantify over. First-order logic can only quantify over sets of atomic propositions. (E.g. For all p . p => p). Second-order logic can quantify over functions on propositions, and higher-order logic can quantify over any type of entity. The sets over which quantifiers operate are usually implicit but can be deduced from well-formedness constraints. In first-order logic quantifiers always range over ALL the elements of the domain of discourse. By contrast, second-order logic allows one to quantify over subsets.
  • flagrante delicto — Law. in the very act of committing the offense.
  • fractal dimension — (mathematics)   A common type of fractal dimension is the Hausdorff-Besicovich Dimension, but there are several different ways of computing fractal dimension. Fractal dimension can be calculated by taking the limit of the quotient of the log change in object size and the log change in measurement scale, as the measurement scale approaches zero. The differences come in what is exactly meant by "object size" and what is meant by "measurement scale" and how to get an average number out of many different parts of a geometrical object. Fractal dimensions quantify the static *geometry* of an object. For example, consider a straight line. Now blow up the line by a factor of two. The line is now twice as long as before. Log 2 / Log 2 = 1, corresponding to dimension 1. Consider a square. Now blow up the square by a factor of two. The square is now 4 times as large as before (i.e. 4 original squares can be placed on the original square). Log 4 / log 2 = 2, corresponding to dimension 2 for the square. Consider a snowflake curve formed by repeatedly replacing ___ with _/\_, where each of the 4 new lines is 1/3 the length of the old line. Blowing up the snowflake curve by a factor of 3 results in a snowflake curve 4 times as large (one of the old snowflake curves can be placed on each of the 4 segments _/\_). Log 4 / log 3 = 1.261... Since the dimension 1.261 is larger than the dimension 1 of the lines making up the curve, the snowflake curve is a fractal. [sci.fractals FAQ].
