  • ferrite core memory — (storage)   (Or "core") An early form of non-volatile storage built (by hand) from tiny rings of magnetisable material threaded onto very fine wire to form large (e.g. 13"x13" or more) rectangluar arrays. Each core stored one bit of data. These were sandwiched between printed circuit boards(?). Sets of wires ran horizontally and vertically and where a vertical and horizontal wire crossed, a core had both wires threaded through it. A single core could be selected and magnetised by passing sufficient current through its horizontal and vertical wires. A core would retain its magnetisation until it was re-magnetised. The two possible polarities of magnetisation were used to represent the binary values zero and one. A third "sense" wire, passed through the core and, if the magnetisation of the core was changed, a small pulse would be induced in the sense wire which could be detected and used to deduce the core's original state. Some core memory was immersed in a bath of heated oil to improve its performance. Core memory was rendered obsolete by semiconductor memory. For example, the 1970s-era NCR 499 had two boards, each with 16 kilobytes of core memory.
  • 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)
  • first world problem — a fairly minor problem, frustrating situation, or complaint associated with a relatively high standard of living, as opposed to the more serious problems associated with poverty: I’m bored with all my electronic gadgets—such a first world problem!
  • fixed-rate mortgage — a home mortgage for which equal monthly payments of interest and principal are paid over the life of the loan, usually for a term of 30 years.
  • fixed-term contract — a contract for a particular and fixed period
  • fractal compression — (algorithm)   A technique for encoding images using fractals.
  • frameshift mutation — a mutation caused by frameshift.
  • freedom of the city — nominal citizenship in a city, conferred as an honor upon important visitors.
  • from pillar to post — an upright shaft or structure, of stone, brick, or other material, relatively slender in proportion to its height, and of any shape in section, used as a building support, or standing alone, as for a monument: Gothic pillars; a pillar to commemorate Columbus.
  • from rags to riches — a worthless piece of cloth, especially one that is torn or worn.
  • gastrocolic omentum — the peritoneal fold attached to the stomach and the colon and hanging over the small intestine.
  • genetic programming — (programming)   (GP) A programming technique which extends the genetic algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems. Genetic programming can solve problems of system identification, classification, control, robotics, optimisation, game playing, and pattern recognition. Starting with a primordial ooze of hundreds or thousands of randomly created programs composed of functions and terminals appropriate to the problem, the population is progressively evolved over a series of generations by applying the operations of Darwinian fitness proportionate reproduction and crossover (sexual recombination).
  • gentleman-pensioner — (formerly) a gentleman-at-arms.
  • geomagnetic equator — an imaginary line on the earth's surface, the plane of which passes through the center and is midway between the geomagnetic poles.
  • geometric isomerism — each of two or more chemical compounds having the same molecular formula but a different geometric arrangement; an unsaturated compound or ring compound in which rotation around a carbon bond is restricted, as in cis- and trans- configurations.
  • geothermal gradient — the increase in temperature with increasing depth within the earth.
  • giant silkworm moth — any silkworm moth of the family Saturniidae.
  • glottalic airstream — a current of air in the pharynx produced by the action of the glottis.
  • golden lion tamarin — a monkey, Leontopithecus rosalia rosalia, of tropical rain forests of southeastern Brazil, having a silky golden coat and a long golden mane: threatened with extinction.
  • government-in-exile — a government temporarily moved to or formed in a foreign land by exiles who hope to establish that government in their native country after its liberation.
  • great idaean mother — Cybele.
  • green mountain boys — the members of the armed bands of Vermont organized in 1770 to oppose New York's territorial claims. Under Ethan Allen they won fame in the War of American Independence
  • grievance committee — a group of representatives chosen from a labor union or from both labor and management to consider and remedy workers' grievances.
  • gross profit margin — A gross profit margin is a measure of the profitability of a company, that is calculated by dividing gross profit by net sales.
  • grosse pointe farms — a city in SE Michigan, near Detroit.
  • hamiltonian problem — (computability)   (Or "Hamilton's problem") A problem in graph theory posed by William Hamilton: given a graph, is there a path through the graph which visits each vertex precisely once (a "Hamiltonian path")? Is there a Hamiltonian path which ends up where it started (a "Hamiltonian cycle" or "Hamiltonian tour")? Hamilton's problem is NP-complete. It has numerous applications, sometimes completely unexpected, in computing.
  • harmonic distortion — distortion caused by nonlinear characteristics of electronic apparatus, esp of audio amplifiers, that generate unwanted harmonics of the input frequencies
  • have a problem with — to be unable to understand or do
  • heart in your mouth — If your heart is in your mouth, you feel very excited, worried, or frightened.
  • heine-borel theorem — the theorem that in a metric space every covering consisting of open sets that covers a closed and compact set has a finite collection of subsets that covers the given set.
  • hermitian conjugate — adjoint (def 2).
  • horizontal mobility — movement from one position to another within the same social level, as changing jobs without altering occupational status, or moving between social groups having the same social status.
  • human rights record — the facts that are known about the tendency of a country, regime, etc, to observe and protect human rights
  • hydropneumatization — utilization of air pressure in the housing of a water turbine to keep the level of water that has been used from rising to interfere with the rotor blades.
  • hyperbolic geometry — the branch of non-Euclidean geometry that replaces the parallel postulate of Euclidean geometry with the postulate that two distinct lines may be drawn parallel to a given line through a point not on the given line.
  • hypercholesteraemia — (medicine) An abnormally high level of cholesterol in the blood.
  • hyperparathyroidism — overactivity of the parathyroid gland, characterized by softening of the bones, with consequent pain, tenderness, and a tendency to spontaneous fractures, and by muscular weakness and abdominal cramps.
