  • electric displacement — the electric flux density when an electric field exists in free space into which a dielectric is introduced
  • electric polarization — Electric polarization is the type of polarization of electricity that occurs in a dielectric.
  • electromagnetic pulse — a surge of electromagnetic radiation, esp one resulting from a nuclear explosion, which can disrupt electronic devices and, occasionally, larger structures and equipment
  • electromyographically — By means of, or in terms of, electromyography.
  • empirical probability — a measure or estimate of the degree of confidence one may have in the occurrence of an event, defined as the proportion observed in a sample
  • endoplasmic reticulum — an extensive intracellular membrane system whose functions include synthesis and transport of lipids and, in regions where ribosomes are attached, of proteins
  • epidemic encephalitis — any type of widespread encephalitis caused by various viruses
  • euro-commercial paper — commercial paper issued in a eurocurrency
  • exposure compensation — the act of overriding a camera's automatic exposure in order to achieve a particular effect or due to difficult lighting conditions
  • flotation compartment — in a boat, an enclosed section filled with air or gas to give buoyancy
  • fluorophosphoric acid — any of three acids containing fluorine and phosphorus, HPF 6 , HPO 2 F 2 , or H 2 PO 3 F.
  • forensic anthropology — the branch of physical anthropology in which anthropological data, criteria, and techniques are used to determine the sex, age, genetic population, or parentage of skeletal or biological materials in questions of civil or criminal law.
  • forward compatibility — (jargon)   The ability to accept input from later versions of itself. Forward compatibility is harder to achieve than backward compatibility, since, in the backward case, the input format is know whereas a forward compatible system needs to cope gracefully with unknown future features. An example of future compatibility is the stipulation that a web browser should ignore HTML tags it does not recognise. See also extensible.
  • framing specification — A specification of the "protocol bits" that surround the "data bits" on a communications channel to allow the data to be "framed" into chunks, like start and stop bits in EIA-232. It allows a receiver to synchronize at points along the data stream.
  • french fried potatoes — a more formal name for chips
  • fuming sulphuric acid — a mixture of pyrosulphuric acid, H2S2O7, and other condensed acids, made by dissolving sulphur trioxide in concentrated sulphuric acid
  • functional dependency — (database)   Given a relation R (in a relational database), attribute Y of R is functionally dependent on attribute X of R and X of R functionally determines Y of R (in symbols R.X -> R.Y) if and only if each X in R has associated with it precisely one Y in R (at any one time). Attributes X and Y may be composite. This is very close to a function in the mathematical sense.
  • functional imperative — a requirement for the survival of any social system, as communication, control of conflict, or socialization.
  • gastrohepatic omentum — lesser omentum.
  • generic type variable — (programming)   (Also known as a "schematic type variable"). Different occurrences of a generic type variable in a type expression may be instantiated to different types. Thus, in the expression let id x = x in (id True, id 1) id's type is (for all a: a -> a). The universal quantifier "for all a:" means that a is a generic type variable. For the two uses of id, a is instantiated to Bool and Int. Compare this with let id x = x in let f g = (g True, g 1) in f id This looks similar but f has no legal Hindley-Milner type. If we say f :: (a -> b) -> (b, b) this would permit g's type to be any instance of (a -> b) rather than requiring it to be at least as general as (a -> b). Furthermore, it constrains both instances of g to have the same result type whereas they do not. The type variables a and b in the above are implicitly quantified at the top level: f :: for all a: for all b: (a -> b) -> (b, b) so instantiating them (removing the quantifiers) can only be done once, at the top level. To correctly describe the type of f requires that they be locally quantified: f :: ((for all a: a) -> (for all b: b)) -> (c, d) which means that each time g is applied, a and b may be instantiated differently. f's actual argument must have a type at least as general as ((for all a: a) -> (for all b: b)), and may not be some less general instance of this type. Type variables c and d are still implicitly quantified at the top level and, now that g's result type is a generic type variable, any types chosen for c and d are guaranteed to be instances of it. This type for f does not express the fact that b only needs to be at least as general as the types c and d. For example, if c and d were both Bool then any function of type (for all a: a -> Bool) would be a suitable argument to f but it would not match the above type for f.
