  • 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.
  • composition rubber — manufactured rubber
  • composition series — a normal series of subgroups in which no additional subgroups can be inserted.
  • compression stroke — The compression stroke is the stroke in an engine in which the air or air/fuel mixture is compressed before ignition.
  • compressor station — A compressor station is a facility with several compressors (= devices that increase the pressure of air or natural gas) and other equipment to pump natural gas under pressure over long distances.

  • constituency party — a branch of a political party operating within a constituency
  • construction paper — Construction paper is a type of stiff, colored paper that children use for drawing and for making things.
  • 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.
  • continuous process — A continuous process is a process in which the product comes out without interruption and not in groups.
  • conversation piece — something, esp an unusual object, that provokes conversation

  • cranial osteopathy — osteopathy that focuses on the cranium and the spine

  • creeping featurism — (jargon)   /kree'ping fee'chr-izm/ (Or "feature creep") A systematic tendency to load more chrome and features onto systems at the expense of whatever elegance they may have possessed when originally designed. "The main problem with BSD Unix has always been creeping featurism." More generally, creeping featurism is the tendency for anything to become more complicated because people keep saying "Gee, it would be even better if it had this feature too". The result is usually a patchwork because it grew one ad-hoc step at a time, rather than being planned. Planning is a lot of work, but it's easy to add just one extra little feature to help someone, and then another, and another, .... When creeping featurism gets out of hand, it's like a cancer. Usually this term is used to describe computer programs, but it could also be said of the federal government, the IRS 1040 form, and new cars. A similar phenomenon sometimes afflicts conscious redesigns; see second-system effect. See also creeping elegance.
  • crystal microphone — a microphone that uses a piezoelectric crystal to convert sound energy into electrical energy
  • customs inspection — an inspection carried out by a customs department
  • daisywheel printer — (printer)   A kind of impact printer where the characters are arranged on the ends of the spokes of a wheel (resembling the petals on a daisy). The wheel (usually made of plastic) is rotated to select the character to print and then an electrically operated hammer mechanism bends the selected spoke forward slightly, sandwiching an ink ribbon between the character and the paper, as in a typewriter. One advantage of this arrangement over that of a typewriter is that different wheels may be inserted to produce different typefaces.
  • deanthropomorphism — the ridding of philosophy or religion of anthropomorphic beliefs and doctrines.
  • deep-discount bond — a fixed-interest security that pays little or no interest but is issued at a substantial discount to its redemption value, thus largely substituting capital gain for income
