Newtonian
(gcide) | Newtonian \New*to"ni*an\, a.
Of or pertaining to Sir Isaac Newton, or his discoveries.
[1913 Webster]
Newtonian philosophy, the philosophy of Sir Isaac Newton;
-- applied to the doctrine of the universe as expounded in
Newton's "Principia," to the modern or experimental
philosophy (as opposed to the theories of Descartes and
others), and, most frequently, to the mathematical theory
of universal gravitation.
Newtonian telescope (Astron.), a reflecting telescope, in
which rays from the large speculum are received by a plane
mirror placed diagonally in the axis, and near the open
end of the tube, and thrown at right angles toward one
side of the tube, where the image is formed and viewed
through the eyeplace.
Newtonian theory of light. See Note under Light.

Newtonian potential
(gcide) | Potential \Po*ten"tial\, n.
1. Anything that may be possible; a possibility; potentially.
--Bacon.
[1913 Webster]
2. (Math.) In the theory of gravitation, or of other forces
acting in space, a function of the rectangular coordinates
which determine the position of a point, such that its
differential coefficients with respect to the coordinates
are equal to the components of the force at the point
considered; -- also called potential function, or {force
function}. It is called also Newtonian potential when
the force is directed to a fixed center and is inversely
as the square of the distance from the center.
[1913 Webster]
3. (Elec.) The energy of an electrical charge measured by its
power to do work; hence, the degree of electrification as
referred to some standard, as that of the earth;
electro-motive force.

[1913 Webster]Telescope \Tel"e*scope\, n. [Gr. ? viewing afar, farseeing; ?
far, far off + ? a watcher, akin to ? to view: cf. F.
t['e]lescope. See Telegraph, and -scope.]
An optical instrument used in viewing distant objects, as the
heavenly bodies.
[1913 Webster]
Note: A telescope assists the eye chiefly in two ways; first,
by enlarging the visual angle under which a distant
object is seen, and thus magnifying that object; and,
secondly, by collecting, and conveying to the eye, a
larger beam of light than would enter the naked organ,
thus rendering objects distinct and visible which would
otherwise be indistinct and or invisible. Its essential
parts are the object glass, or concave mirror, which
collects the beam of light, and forms an image of the
object, and the eyeglass, which is a microscope, by
which the image is magnified.
[1913 Webster]
Achromatic telescope. See under Achromatic.
Aplanatic telescope, a telescope having an aplanatic
eyepiece.
Astronomical telescope, a telescope which has a simple
eyepiece so constructed or used as not to reverse the
image formed by the object glass, and consequently
exhibits objects inverted, which is not a hindrance in
astronomical observations.
Cassegrainian telescope, a reflecting telescope invented by
Cassegrain, which differs from the Gregorian only in
having the secondary speculum convex instead of concave,
and placed nearer the large speculum. The Cassegrainian
represents objects inverted; the Gregorian, in their
natural position. The Melbourne telescope (see Illust.
under Reflecting telescope, below) is a Cassegrainian
telescope.
Dialytic telescope. See under Dialytic.
Equatorial telescope. See the Note under Equatorial.
Galilean telescope, a refracting telescope in which the
eyeglass is a concave instead of a convex lens, as in the
common opera glass. This was the construction originally
adopted by Galileo, the inventor of the instrument. It
exhibits the objects erect, that is, in their natural
positions.
Gregorian telescope, a form of reflecting telescope. See
under Gregorian.
Herschelian telescope, a reflecting telescope of the form
invented by Sir William Herschel, in which only one
speculum is employed, by means of which an image of the
object is formed near one side of the open end of the
tube, and to this the eyeglass is applied directly.
Newtonian telescope, a form of reflecting telescope. See
under Newtonian.
Photographic telescope, a telescope specially constructed
to make photographs of the heavenly bodies.
Prism telescope. See Teinoscope.
Reflecting telescope, a telescope in which the image is
formed by a speculum or mirror (or usually by two
speculums, a large one at the lower end of the telescope,
and the smaller one near the open end) instead of an
object glass. See {Gregorian, Cassegrainian, Herschelian,
& Newtonian, telescopes}, above.
Refracting telescope, a telescope in which the image is
formed by refraction through an object glass.
Telescope carp (Zool.), the telescope fish.
Telescope fish (Zool.), a monstrous variety of the goldfish
having very protuberant eyes.
Telescope fly (Zool.), any two-winged fly of the genus
Diopsis, native of Africa and Asia. The telescope flies
are remarkable for having the eyes raised on very long
stalks.
Telescope shell (Zool.), an elongated gastropod ({Cerithium
telescopium}) having numerous flattened whorls.
Telescope sight (Firearms), a slender telescope attached to
the barrel, having cross wires in the eyepiece and used as
a sight.
Terrestrial telescope, a telescope whose eyepiece has one
or two lenses more than the astronomical, for the purpose
of inverting the image, and exhibiting objects erect.
