| numerical taxonomy | <zoology> Study of the relationships of taxa by the application of numerical similarity values to characters so as to rank into categories based on degree of overall similarity. (09 Jan 1998) |

| taxonomy | <zoology> The theories and techniques of naming, describing, and classifying organisms, the study of the relationships of taxa,including positional changes which do not involve changes in the names of taxa. The taxonomic hierarchy is, from top to bottom: kingdom, phylum (for animals) or division (for plants and fungi), class, order, family, genus, species. (09 Jan 1998) |
| numerical | 1. Belonging to number; denoting number; consisting in numbers; expressed by numbers, and not letters; as, numerical characters; a numerical equation; a numerical statement. Numerical, as opposed to algebraical, is used to denote a value irrespective of its sign; thus, -5 is numerically greater than -3, though algebraically less. 2. The same in number; hence, identically the same; identical; as, the same numerical body. "Would to God that all my fellow brethren, which with me bemoan the loss of their books, . . . Might rejoice for the recovery thereof, though not the same numerical volumes. <mathematics>" (Fuller) Numerical equation, an equation which has all the quantities except the unknown expressed in numbers; distinguished from literal equation. Numerical value of an equation or expression, that deduced by substituting numbers for the letters, and reducing. Origin: Cf. F. Numerique. See Number. Source: Websters Dictionary (01 Mar 1998) |
| numerical analysis, computer-assisted | Computer-assisted study of methods for obtaining useful quantitative solutions to problems that have been expressed mathematically. (12 Dec 1998) |
| numerical aperture | For a lens the resolving power depends upon the wavelength of light being used and inversely upon the numerical aperture. The N.A. Is the product of the refractive index of the medium (1 for air, 1.5 for immersion oil) and the sine of the angle, i, the semi angle of the cone formed by joining objects to the perimeter of the lens. The larger the value of N.A., the better the resolving power of the lens, most objectives have their N.A. Value engraved on the barrel and this should be quoted when describing an optical system. (18 Nov 1997) |
| numerical hypertrophy | <pathology> The abnormal multiplication or increase in the number of normal cells in normal arrangement in a tissue. Compare: hypertrophy. Origin: Gr. Plasis = formation (18 Nov 1997) |
| numerical notation for teeth | <dentistry> The numerical notation for teeth is an alternate to Palmer's notation. In this notation, the centrals are designated as 1's, the laterals as 2's, the cuspids as 3's, the first bicuspids as 4's, the second bicuspid's as 5's, etc. (08 Jan 1998) |
| universal numerical notation for teeth | <dentistry> The universal numerical notation is an alternative numerical notation for teeth. In this notation, your upper right third molar is designated as tooth#1, and then you number each tooth sequentially moving right to left and down across your mouth. (08 Jan 1998) |
| numerical taxonomy |
same as phenetics; a method of generating phylogenies that is based on large numbers of quantifiable (measurable) characters which groups organisms with respect to overall similarity

| numerical taxonomy |
measures overall similarity of taxa; relationships are displayed using phenograms; similarities may be the result of convergence, not homology.
