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..

Reciprocal :: Reciprocal (n.) The quotient arising from dividing unity by any quantity; thus, / is the reciprocal of 4; 1/(a +b) is the reciprocal of a + b. The reciprocal of a fraction is the fraction inverted, or the denominator divided by the numerator..

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..

Millesimal :: Millesimal (a.) Thousandth; consisting of thousandth parts; as, millesimal fractions..

Anaclastic :: Anaclastic (a.) Produced by the refraction of light, as seen through water; as, anaclastic curves..

Fractional :: Fractional (a.) Of or pertaining to fractions or a fraction; constituting a fraction; as, fractional numbers..

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..

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..

Anaclastics :: Anaclastics (n.) That part of optics which treats of the refraction of light; -- commonly called dioptrics.

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

Fractional :: Fractional (a.) Relatively small; inconsiderable; insignificant; as, a fractional part of the population..

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..

Fraction :: Fraction (n.) A portion; a fragment.

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..

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..

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..

Increment :: Increment (n.) The increase of a variable quantity or fraction from its present value to its next ascending value; the finite quantity, generally variable, by which a variable quantity is increased..

Spectrum :: Spectrum (n.) The several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. See Illust. of Light, and Spectroscope..

Uniaxial :: Uniaxial (a.) Having but one optic axis, or line of no double refraction..

Abbreviate :: Abbreviate (v. t.) To reduce to lower terms, as a fraction..
