    • Infinity Endless or indefinite number; great multitude; as an infinity of beauties.
    • Infinity (Geom) That part of a line, or of a plane, or of space, which is infinitely distant. In modern geometry, parallel lines or planes are sometimes treated as lines or planes meeting at infinity.
    • Infinity Unlimited capacity, energy, excellence, or knowledge; as, the infinity of God and his perfections.
    • Infinity Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity. "There can not be more infinities than one; for one of them would limit the other."

    • n infinity The condition of being infinite or the greatest possible; immeasurableness; innumerability; perfection: as, the infinity of God; infinity of duration.
    • n infinity Unlimited extension; figuratively, exhaustless quantity or number: as, inconceivable infinity; an infinity of details.
    • n infinity In geometry, the part of space at an infinite distance from the part chiefly considered. Owing to the mechanical properties of the straight line, the most important mode of geometrical transformation is that which transforms every straight line into a straight line, its position only being changed. But this transforms the part of space at infinity into a plane, just as in a perspective view of an unbounded plane the infinitely distant parts are compressed into a line. Hence, mathematicians generally speak of the plane at infinity, or the line at infinity in a plane. In analytical geometry the plane at infinity is best considered as two coincident planes, fastened together at an imaginary nodal circle, and constituting a degenerate sphere, called the sphere at infinity. (See absolute, n., 2.) In the theory of functions, the most important mode of transformation of the plane is one which preserves the magnitudes of all angles, and this transforms the infinitely distant parts of the plane into a point; hence, in that branch of mathematics, the point at infinity is spoken of.
    • n infinity An infinite number: as, an infinity of straight lines. Its symbol is ∞.
