  • exclamation mark — (character)   The character "!" with ASCII code 33. Common names: bang; pling; excl (/eks'kl/); shriek; ITU-T: exclamation mark, exclamation point (US). Rare: factorial; exclam; smash; cuss; boing; yell; wow; hey; wham; eureka; soldier; INTERCAL: spark-spot. The Commonwealth Hackish, "pling", is common among Acorn Archimedes owners. Bang is more common in the USA. The occasional CMU usage, "shriek", is also used by APL fans and mathematicians, especially category theorists. Exclamation mark is used in C and elsewhere as the logical negation operation (NOT).
  • extrachromosomal — Happening outside a chromosome.
  • extracorporeally — Outside the body.
  • false beechdrops — either of two parasitic or saprophytic plants of the genus Monotropa, especially the tawny or reddish M. hypopithys (false beechdrops) of eastern North America.
  • family of curves — a collection of curves whose equations differ only by values assigned a parameter or parameters.
  • feedback control — (electronics)   A control system which monitors its effect on the system it is controlling and modifies its output accordingly. For example, a thermostat has two inputs: the desired temperature and the current temperature (the latter is the feedback). The output of the thermostat changes so as to try to equalise the two inputs. Computer disk drives use feedback control to position the read/write heads accurately on a recording track. Complex systems such as the human body contain many feedback systems that interact with each other; the homeostasis mechanisms that control body temperature and acidity are good examples.
