  • curvature of the spine — a condition in which the spine is abnormally curved
  • dalton's atomic theory — the theory that matter consists of indivisible particles called atoms and that atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules). The theory was the basis of modern chemistry
  • de broglie wave length — 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.
  • dehydroepiandrosterone — the most abundant steroid in the human body, that is involved in the manufacture of testosterone, oestrogen, progesterone, and corticosterone
  • delayed-action shutter — a camera shutter that opens after an interval set by the photographer
  • directional microphone — a microphone that has a greater sensitivity to sounds coming from a particular area in front of it: used to eliminate unwanted sounds.
  • disposable soma theory — the theory that ageing is caused by the body having increasingly fewer resources to allocate towards repairing wear and damage to tissues
  • dominant seventh chord — a chord consisting of the dominant and the major third, perfect fifth, and minor seventh above it. Its most natural resolution is to a chord on the tonic

  • drumhead court-martial — a court-martial held, usually on a battlefield, for the summary trial of charges of offenses committed during military operations.
  • earth inductor compass — a compass actuated by induction from the earth's magnetic field.
  • ectotrophic mycorrhiza — a type of mycorrhiza, typical of temperate and Boreal trees, in which the fungus forms a layer on the outside of the roots of the plant

  • electrothermal printer — a printer that produces characters by burning the image on specially coated paper
  • endotrophic mycorrhiza — the most widespread and common type of mycorrhiza, in which the fungus lives within the cells of the roots of the plant
  • enhanced parallel port — (hardware)   (EPP) A parallel port that confirms to the IEEE's EPP standard. An EPP is actually an expansion bus that can handle 64 disk drives and other peripherals.
  • every now and then etc — You use every in the expressions every now and then, every now and again, every once in a while, and every so often in order to indicate that something happens occasionally.
  • evolutionary algorithm — (EA) An algorithm which incorporates aspects of natural selection or survival of the fittest. An evolutionary algorithm maintains a population of structures (usually randomly generated initially), that evolves according to rules of selection, recombination, mutation and survival, referred to as genetic operators. A shared "environment" determines the fitness or performance of each individual in the population. The fittest individuals are more likely to be selected for reproduction (retention or duplication), while recombination and mutation modify those individuals, yielding potentially superior ones. EAs are one kind of evolutionary computation and differ from genetic algorithms. A GA generates each individual from some encoded form known as a "chromosome" and it is these which are combined or mutated to breed new individuals. EAs are useful for optimisation when other techniques such as gradient descent or direct, analytical discovery are not possible. Combinatoric and real-valued function optimisation in which the optimisation surface or fitness landscape is "rugged", possessing many locally optimal solutions, are well suited for evolutionary algorithms.
