  • combustion furnace — a furnace used in the laboratory to carry out elemental analysis of organic compounds
  • compassion fatigue — the inability to react sympathetically to a crisis, disaster, etc, because of overexposure to previous crises, disasters, etc
  • composite function — a function obtained from two given functions, where the range of one function is contained in the domain of the second function, by assigning to an element in the domain of the first function that element in the range of the second function whose inverse image is the image of the element.
  • configuration item — (jargon)   Hardware or software, or an aggregate of both, which is designated by the project configuration manager (or contracting agency) for configuration management.
  • considered harmful — (programming, humour)   A type of phrase based on the title of Edsger W. Dijkstra's famous note in the March 1968 Communications of the ACM, "Goto Statement Considered Harmful", which fired the first salvo in the structured programming wars. Amusingly, the ACM considered the resulting acrimony sufficiently harmful that it will (by policy) no longer print articles taking so assertive a position against a coding practice. In the ensuing decades, a large number of both serious papers and parodies bore titles of the form "X considered Y". The structured-programming wars eventually blew over with the realisation that both sides were wrong, but use of such titles has remained as a persistent minor in-joke.
  • constructive proof — (mathematics)   A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.

  • fibonacci sequence — (mathematics)   The infinite sequence of numbers beginning 1, 1, 2, 3, 5, 8, 13, ... in which each term is the sum of the two terms preceding it. The ratio of successive Fibonacci terms tends to the golden ratio, namely (1 + sqrt 5)/2.
  • fibrocartilaginous — a type of cartilage having a large number of fibers.
  • field of quotients — a field whose elements are pairs of elements of a given commutative integral domain such that the second element of each pair is not zero. The field of rational numbers is the field of quotients of the integral domain of integers.
  • fire in your belly — If you say that someone has fire in their belly, you are expressing approval of them because they are energetic, enthusiastic, and have very strong feelings.
  • first class module — (programming)   A module that is a first class data object of the programming language, e.g. a record containing functions. In a functional language, it is standard to have first class programs, so program building blocks can have the same status.
  • first duke of york — a member of the royal house of England that ruled from 1461 to 1485.
  • first-in first-out — (algorithm)   (FIFO, or "queue") A data structure or hardware buffer from which items are taken out in the same order they were put in. Also known as a "shelf" from the analogy with pushing items onto one end of a shelf so that they fall off the other. A FIFO is useful for buffering a stream of data between a sender and receiver which are not synchronised - i.e. not sending and receiving at exactly the same rate. Obviously if the rates differ by too much in one direction for too long then the FIFO will become either full (blocking the sender) or empty (blocking the receiver). A Unix pipe is a common example of a FIFO. A FIFO might be (but isn't ever?) called a LILO - last-in last-out. The opposite of a FIFO is a LIFO (last-in first-out) or "stack".
  • fissure of rolando — central sulcus.
  • fissure of sylvius — lateral fissure.
  • fitness instructor — physical trainer, exercise teacher
  • fixed-focus camera — a camera with an unadjustable focal length and with a relatively large depth of field.

  • fluorodeoxyglucose — (carbohydrate) A fluorine analog of glucose that is used in positron emission tomography.
  • football supporter — a person who supports a particular football team
  • for the rest of us — (abuse)   (From the Macintosh slogan "The computer for the rest of us") 1. Used to describe a spiffy product whose affordability shames other comparable products, or (more often) used sarcastically to describe spiffy but very overpriced products. 2. Describes a program with a limited interface, deliberately limited capabilities, non-orthogonality, inability to compose primitives, or any other limitation designed to not "confuse" a naïve user. This places an upper bound on how far that user can go before the program begins to get in the way of the task instead of helping accomplish it. Used in reference to Macintosh software which doesn't provide obvious capabilities because it is thought that the poor luser might not be able to handle them. Becomes "the rest of *them*" when used in third-party reference; thus, "Yes, it is an attractive program, but it's designed for The Rest Of Them" means a program that superficially looks neat but has no depth beyond the surface flash. See also point-and-drool interface, user-friendly.
  • forethoughtfulness — The condition of being forethoughtful.
  • forget-me-not blue — a shade of blue similar to the shade of the flowers of a forget-me-not
