Infraction :: Infraction (n.) The act of infracting or breaking; breach; violation; nonobservance; infringement; as, an infraction of a treaty, compact, rule, or law..

Refraction :: Refraction (n.) The change in the direction of a ray of light, and, consequently, in the apparent position of a heavenly body from which it emanates, arising from its passage through the earth's atmosphere; -- hence distinguished as atmospheric refraction, or astronomical refraction..

Refracted :: Refracted (a.) Turned from a direct course by refraction; as, refracted rays of light..

Stereoscopic :: Stereoscope (n.) An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer..

Refractive :: Refractive (a.) Serving or having power to refract, or turn from a direct course; pertaining to refraction; as, refractive surfaces; refractive powers..

Irrational :: Irrational (a.) Not capable of being exactly expressed by an integral number, or by a vulgar fraction; surd; -- said especially of roots. See Surd..

Fractionally :: Fractionally (adv.) By fractions or separate portions; as, to distill a liquid fractionally, that is, so as to separate different portions..

Dioptrics :: Dioptrics (n.) The science of the refraction of light; that part of geometrical optics which treats of the laws of the refraction of light in passing from one medium into another, or through different mediums, as air, water, or glass, and esp. through different lenses; -- distinguished from catoptrics, which refers to reflected light..

Neurine :: Neurine (n.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide..

Lap :: Lap (n.) One circuit around a race track, esp. when the distance is a small fraction of a mile; as, to run twenty laps; to win by three laps. See Lap, to fold, 2..

Numerator :: Numerator (n.) The term in a fraction which indicates the number of fractional units that are taken.

Fringe :: Fringe (n.) One of a number of light or dark bands, produced by the interference of light; a diffraction band; -- called also interference fringe..

Algorithm :: Algorithm (n.) The art of calculating with any species of notation; as, the algorithms of fractions, proportions, surds, etc..

Refraction :: Refraction (n.) The correction which is to be deducted from the apparent altitude of a heavenly body on account of atmospheric refraction, in order to obtain the true altitude..

Iceland Spar :: Iceland spar () A transparent variety of calcite, the best of which is obtained in Iceland. It is used for the prisms of the polariscope, because of its strong double refraction. Cf. Calcite..

Rule :: Rule (a.) A measuring instrument consisting of a graduated bar of wood, ivory, metal, or the like, which is usually marked so as to show inches and fractions of an inch, and jointed so that it may be folded compactly..

Integer :: Integer (n.) A complete entity; a whole number, in contradistinction to a fraction or a mixed number..

Scrip :: Scrip (n.) Paper fractional currency.

Parabola :: Parabola (n.) One of a group of curves defined by the equation y = axn where n is a positive whole number or a positive fraction. For the cubical parabola n = 3; for the semicubical parabola n = /. See under Cubical, and Semicubical. The parabolas have infinite branches, but no rectilineal asymptotes..

Fraction :: Fraction (n.) The act of breaking, or state of being broken, especially by violence..
