  • compensation order — (in Britain) the requirement of a court that an offender pay compensation for injury, loss, or damage resulting from an offence, either in preference to or as well as a fine
  • complementarianism — The doctrine that genders in a society should have complementary roles.
  • complementary base — either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA.
  • complexity measure — (algorithm)   A quantity describing the complexity of a computation.
  • composition rubber — manufactured rubber
  • composition series — a normal series of subgroups in which no additional subgroups can be inserted.
  • comprehensibleness — The quality of being comprehensible; comprehensibility.
  • compression stroke — The compression stroke is the stroke in an engine in which the air or air/fuel mixture is compressed before ignition.
  • compressor program — a computer program that compresses data
  • 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.
  • computer scientist — a person with advanced knowledge of computers and how they work
  • concentration span — the length of time a person can concentrate on something
  • conceptual realism — the doctrine that universals have real and independent existence.
  • connected subgraph — (mathematics)   A connected graph consisting of a subset of the nodes and edges of some other graph.

  • 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
  • cordless telephone — a portable battery-powered telephone with a short-range radio link to a fixed base unit

  • counter-hypothesis — a proposition, or set of propositions, set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation (working hypothesis) or accepted as highly probable in the light of established facts.

  • creatine phosphate — phosphocreatine.
  • crookes dark space — the dark space between the cathode glow and the negative glow in a vacuum tube, occurring when the pressure is low.
  • crystal microphone — a microphone that uses a piezoelectric crystal to convert sound energy into electrical energy
  • cursor dipped in x — (jargon)   The metaphorical source of the electronic equivalent of a poisoned-pen letter. Derived from English metaphors of the form "pen dipped in X" (where X = e.g. "acid", "bile", "vitriol"). These map over neatly to this hackish usage (the cursor being what moves, leaving letters behind, when one is composing on-line). "Talk about a nastygram! He must've had his cursor dipped in acid when he wrote that one!"
  • curvature of space — (in relativity) a property of space near massive bodies in which their gravitational field causes light to travel along curved paths.
