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..

Separatrix :: Separatrix (n.) The decimal point; the dot placed at the left of a decimal fraction, to separate it from the whole number which it follows. The term is sometimes also applied to other marks of separation..

Round :: Round (a.) Full; complete; not broken; not fractional; approximately in even units, tens, hundreds, thousands, etc.; -- said of numbers..

Fraction :: Fraction (n.) One or more aliquot parts of a unit or whole number; an expression for a definite portion of a unit or magnitude.

Rainbow :: Rainbow (n.) A bow or arch exhibiting, in concentric bands, the several colors of the spectrum, and formed in the part of the hemisphere opposite to the sun by the refraction and reflection of the sun's rays in drops of falling rain..

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..

Breach :: Breach (n.) Specifically: A breaking or infraction of a law, or of any obligation or tie; violation; non-fulfillment; as, a breach of contract; a breach of promise..

Decimal :: Decimal (n.) A number expressed in the scale of tens; specifically, and almost exclusively, used as synonymous with a decimal fraction..

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

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

Denominator :: Denominator (n.) That number placed below the line in vulgar fractions which shows into how many parts the integer or unit is divided.

Refractometer :: Refractometer (n.) A contrivance for exhibiting and measuring the refraction of light.

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..

Denominator :: Denominator (n.) That part of any expression under a fractional form which is situated below the horizontal line signifying division.

Eriometer :: Eriometer (n.) An instrument for measuring the diameters of minute particles or fibers, from the size of the colored rings produced by the diffraction of the light in which the objects are viewed..

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

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..

Integral :: Integral (a.) Of, pertaining to, or being, a whole number or undivided quantity; not fractional..

Sexagesimal :: Sexagesimal (n.) A sexagesimal fraction.
