  • diamond-leaf laurel — a tree, Pittosporum rhombifolium, of Australia, having coarsely toothed, oval or diamond-shaped leaves and white flowers, widely planted as an ornamental in the southwestern U.S.
  • dielectric constant — Electricity. the ratio of the flux density produced by an electric field in a given dielectric to the flux density produced by that field in a vacuum.
  • diethylaminoethanol — a colorless, hygroscopic, water-soluble liquid, C 6 H 15 NO, used for the synthesis of local anesthetics, in antirust compounds, and in photographic emulsions.
  • digital electronics — (electronics)   The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
  • dimethylnitrosamine — a yellow, water-soluble carcinogenic liquid, C 2 H 6 N 2 O, found in tobacco smoke and certain foods: known to be a potent carcinogen. Abbreviation: DMN, DMNA.
  • diplomatic immunity — exemption from taxation, searches, arrest, etc., enjoyed by diplomatic officials and their dependent families under international law, and usually on a reciprocal basis.
  • direct grant school — (in Britain, formerly) a school financed by endowment, fees, and a state grant conditional upon admittance of a percentage of nonpaying pupils nominated by the local education authority
  • directional coupler — (communications)   (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
  • disciplinary action — punishment or caution
  • 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).
  • diversional therapy — the structured use of leisure time in recreation and play as a form of or supplement to conventional therapy
  • dobsonian telescope — a relatively inexpensive Newtonian telescope, suitable for visual but not photographic use, in which the tube assembly slips freely in the lower base.
  • dominant wavelength — the wavelength of monochromatic light that would give the same visual sensation if combined in a suitable proportion with an achromatic light
  • don't make me laugh — Some people reply to other people's comments or opinions by saying 'Don't make me laugh' when they disagree with them and think they are foolish or inaccurate.
  • draw the color line — to impose or accept the color line
  • drill-down analysis — drill down
  • drink the health of — to salute or celebrate with a toast
  • 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).
  • dynatron oscillator — type of oscillator
  • east-west relations — relations between the United States and its allies in the western alliance and the Soviet Union, it allies and other Communist countries, especially during the period between the end of World War II and the fall of the Soviet regime
  • eastern coral snake — any of numerous venomous elapid snakes, found chiefly in the New World tropics, as Micrurus fulvius (eastern coral snake) of the southeastern U.S., often brilliantly marked with bands of red, yellow, and black.
  • eat someone's lunch — to take into the mouth and swallow for nourishment; chew and swallow (food).
  • echoencephalography — a device that employs reflected ultrasonic waves to examine the position of brain structures.
  • ecumenical movement — See under ecumenical (def 4).
  • educational adviser — a person who provides advice and training to teachers about teaching methods and educational policies
  • eilean donan castle — a castle near the Kyle of Lochalsh in Highland, Scotland: built in the 13th century; famous for its picturesque setting
  • 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
  • electrode potential — the potential difference developed when an electrode of an element is placed in a solution containing ions of that element
  • electrodynamometers — Plural form of electrodynamometer.

  • electronic keyboard — a typewriter keyboard used to operate an electronic device such as a computer, word processor, etc
  • electronic magazine — (messaging, publication, web)   (e-zine) A regular publication on some particular topic distributed in digital form, chiefly now via the web but also by electronic mail or floppy disk. E-zines are often distributed for free by enthusiasts.
  • electrostatic units — the system of CGS electric and magnetic units that assigns the value of one to the dielectric constant of a vacuum
  • elevator controller — An archetypal dumb embedded-systems application, like toaster (which superseded it). During one period (1983--84) in the deliberations of ANSI X3J11 (the C standardisation committee) this was the canonical example of a really stupid, memory-limited computation environment. "You can't require "printf(3)" to be part of the default run-time library - what if you're targeting an elevator controller?" Elevator controllers became important rhetorical weapons on both sides of several holy wars.
  • emotional blackmail — a way of persuading someone to do something they do not want to do by making them feel guilty about it
  • employment tribunal — (in England, Scotland, and Wales) a tribunal that rules on disputes between employers and employees regarding unfair dismissal, redundancy, etc
