  • de broglie equation — the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv (de Broglie wavelength) where h is Planck's constant.
  • death of a salesman — a play (1949) by Arthur Miller.
  • deathbed confession — a confession that somebody makes just before he or she dies, usually relating to some long concealed crime or secret
  • decontextualization — to remove (a linguistic element, an action, etc.) from a context: decontextualized works of art displayed in museums.
  • deflate compression — deflate
  • deindustrialisation — Alternative spelling of deindustrialization.
  • deindustrialization — the decline in importance of manufacturing industry in the economy of a nation or area
  • department chairman — the chairman of a university department
  • departmentalisation — Alternative spelling of departmentalization.
  • departmentalization — to divide into departments.
  • diamond-point spoon — a spoon having a handle terminating in a polygonal, pointed knob.
  • difference equation — (mathematics)   A relation between consecutive elements of a sequence. The first difference is D u(n) = u(n+1) - u(n) where u(n) is the nth element of sequence u. The second difference is u(n+2) + a u(n+1) + b u(n) = 0 can be converted to a difference equation (in this case, a second order linear difference equation): D2 u(n) + p D u(n) + q u(n) = 0 and vice versa. a, b, p, q are constants.
  • diffraction pattern — the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
  • dihydrostreptomycin — an antibiotic, C 21 H 41 N 7 O 12 , derived by organic synthesis from and believed to be less toxic than streptomycin: used in the form of its sulfate chiefly in the treatment of tuberculosis.
  • dimetric projection — a type of axonometric projection in which the object is shown with two of its three principal axes tilted equally from the plane of viewing
  • disciplinary action — punishment or caution
  • discriminated union — (theory)   The discriminated union of two sets A and B is A + B = {(inA, a) | a in A} U {(inB, b)| b in B} where inA and inB are arbitrary tags which specify which summand an element originates from. A type (especially an algebraic data type) might be described as a discriminated union if it is a sum type whose objects consist of a tag to say which part of the union they belong to and a value of the corresponding type.
  • disjunctive pronoun — an inflection of pronouns in some languages that is used alone or after a preposition, such as moi in French
  • dispersion relation — the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector (k). Thus the wave's speed is ω/k
  • distillation column — a type of still fitted with interior baffles, used for fractional distillation. Compare still2 (def 1).
  • do not disturb sign — A do not disturb sign is a sign that a guest in a hotel hangs outside their room to tell other people not to knock the door or enter.
  • don the baggy green — to represent Australia at Test cricket
  • draw the curtain on — to end
  • dred scott decision — Barbara Ann, 1928–2012, Canadian figure skater.
  • dynamic translation — (architecture)   A virtual machine implementation approach, used to speed up execution of byte-code programs. To execute a program unit such as a method or a function, the virtual machine compiles its bytecodes into (hardware) machine code. The translated code is also placed in a cache, so that next time that unit's machine code can be executed immediately, without repeating the translation. This technique was pioneered by the commercial Smalltalk implementation currently known as VisualWorks, in the early 1980s. Currently it is also used by some implementations of the Java Virtual Machine under the name JIT (Just In Time compilation).
  • elastic deformation — In elastic deformation a material changes shape when a stress is applied to it but goes back to its original state when the stress is removed.
  • electro-shock baton — a baton used as a weapon to pass an electric current through part of the body
  • electronic ignition — any system that uses an electronic circuit to supply the voltage to the sparking plugs of an internal-combustion engine
  • end of transmission — (character)   (EOT) The mnemonic for ASCII character 4.
  • end-to-end solution — (jargon)   (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution.
  • energy conservation — concerted formal or government action or policy to make sure that energy is not wasted
  • entry qualification — the qualifications and conditions required to join an organization, club, etc
  • european commission — the executive body of the European Union formed in 1967, which initiates action in the EU and mediates between member governments
  • exterior decoration — the painting of the outside of a building
  • fallacy of division — the fallacy of inferring that a property of the whole is also a property of parts or members of the whole (opposed to fallacy of composition).
  • feast of dedication — Hanukkah.
  • feast one's eyes on — to look at with pleasure or admiration
  • february revolution — Russian Revolution (def 1).
  • february-revolution — Also called February Revolution. the uprising in Russia in March, 1917 (February Old Style), in which the Czarist government collapsed and a provisional government was established.

  • first law of motion — any of three laws of classical mechanics, either the law that a body remains at rest or in motion with a constant velocity unless an external force acts on the body (first law of motion) the law that the sum of the forces acting on a body is equal to the product of the mass of the body and the acceleration produced by the forces, with motion in the direction of the resultant of the forces (second law of motion) or the law that for every force acting on a body, the body exerts a force having equal magnitude and the opposite direction along the same line of action as the original force (third law of motion or law of action and reaction)
  • fix someone's wagon — any of various kinds of four-wheeled vehicles designed to be pulled or having its own motor and ranging from a child's toy to a commercial vehicle for the transport of heavy loads, delivery, etc.
  • floating foundation — a foundation used in yielding soil, having for its footing a raft tending to displace a weight greater than that of the building.
