point [
pȯint]
(geography)
A tapering piece of land projecting into a body of water; it is generally less prominent than a cape.
(graphic arts)
A printer's unit of measurement, equivalent to 0.013837 inch (approximately ¹⁄₇₂ inch) or ¹⁄₁₂ pica; six lines of 12-point type measure 1 inch. Also known as printer's point; typography point.
(lapidary)
A unit of mass, used in measuring precious stones, equal to 0.01 metric carat, or to 2 milligrams.
(mathematics)
An element in a topological space.
One of the basic undefined elements of geometry possessing position but no nonzero dimension.
In positional notation, the character or the location of an implied symbol that separates the integral part of a numerical expression from its fractional part; for example, it is called the binary point in binary notation and the decimal point in decimal notation.
(navigation)
In marine operation, one thirty-second of a circle, or 11¼ degrees.
point
point - 1. (Sometimes abbreviated "pt") The unit of
length used in typography to specify text character height,
rule width, and other small measurements.
There are six slightly different definitions: Truchet point,
Didot point, ATA point, TeX point, Postscript point,
and IN point.
In Europe, the most commonly used is Didot and in the US, the
formerly standard ATA point has essentially been replaced by
the PostScript point due to the demise of traditional
typesetting systems and rise of desktop computer based systems
running software such as QuarkXPress, Adobe InDesign and
Adobe Pagemaker.
There are 20 twips in a point and 12 points in a pica
(known as a "Cicero" in the Didot system).
Different point systems. | |
Point a feature of an animal’s physical qualities used in evaluating an animal’s body conformation, breed traits, age, sexual development, health, productivity or performance, and breeding value. The points of an animal are considered collectively and in relation to one another. Different points are distinguished for different animal species and for the evaluation of different forms of productivity. A general evaluation is reached by adding up the points.

The principal points of a horse are shown in Figure 1.
Point a fundamental concept in geometry. In systematic expositions of geometry, the point is usually regarded as one of the primitive concepts. In modern mathematics the elements of various spaces are called points. In n-dimensional Euclidean space, for example, a point is an ordered set of n numbers. The points of different spaces may be of a very different nature.
Points having special names are encountered in many areas of mathematics. In geometry, for example, the singular points of curves may be studied. Such points include cusps, isolated points, points of inflection, natural boundary points, nodes, points of osculation, and corner points. Mathematical analysis deals with such singular points as critical points of differential equations and singularities of analytic functions. In set theory, a number of points characterizing the properties of a given set have received special names—for example, limit points, density points, and boundary points.
