is made towards the perpendicular. --Sir I.
Newton.
[1913 Webster]
3. (Astron.)
(a) 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.

Conical refraction (Opt.), the refraction of a ray of light
into an infinite number of rays, forming a hollow cone.
This occurs when a ray of light is passed through crystals
of some substances, under certain circumstances. Conical
refraction is of two kinds; external conical refraction,
in which the ray issues from the crystal in the form of a
cone, the vertex of which is at the point of emergence;
and internal conical refraction, in which the ray is
changed into the form of a cone on entering the crystal,
from which it issues in the form of a hollow cylinder.
This singular phenomenon was first discovered by Sir W. R.
Hamilton by mathematical reasoning alone, unaided by
experiment.

apparent place of one object relative to a second object
near it, due to refraction; also, the correction required
to be made to the observed relative places of the two
bodies.
Double refraction (Opt.), the refraction of light in two
directions, which produces two distinct images. The power
of double refraction is possessed by all crystals except
those of the isometric system. A uniaxial crystal is said
to be optically positive (like quartz), or optically
negative (like calcite), or to have positive, or negative,
double refraction, according as the optic axis is the axis
of least or greatest elasticity for light; a biaxial
crystal is similarly designated when the same relation
holds for the acute bisectrix.
Index of refraction. See under Index.
Refraction circle (Opt.), an instrument provided with a
graduated circle for the measurement of refraction.
Refraction of latitude, longitude, declination, {right
ascension}, etc., the change in the apparent latitude,
longitude, etc., of a heavenly body, due to the effect of
atmospheric refraction.
Terrestrial refraction, the change in the apparent altitude
of a distant point on or near the earth's surface, as the
top of a mountain, arising from the passage of light from
it to the eye through atmospheric strata of varying
density.

Total differential
(gcide) | Differential \Dif`fer*en"tial\, n.
1. (Math.) An increment, usually an indefinitely small one,
which is given to a variable quantity.
[1913 Webster]
Note: According to the more modern writers upon the
differential and integral calculus, if two or more
quantities are dependent on each other, and subject to
increments of value, their differentials need not be
small, but are any quantities whose ratios to each
other are the limits to which the ratios of the
increments approximate, as these increments are reduced
nearer and nearer to zero.
[1913 Webster]
2. A small difference in rates which competing railroad
lines, in establishing a common tariff, allow one of their
number to make, in order to get a fair share of the
business. The lower rate is called a differential rate.
Differentials are also sometimes granted to cities.
[1913 Webster]
3. (Elec.)
(a) One of two coils of conducting wire so related to one
another or to a magnet or armature common to both,
that one coil produces polar action contrary to that
of the other.
(b) A form of conductor used for dividing and distributing
the current to a series of electric lamps so as to
maintain equal action in all. --Knight.
[1913 Webster]
Partial differential (Math.), the differential of a
function of two or more variables, when only one of the
variables receives an increment.
Total differential (Math.), the differential of a function
of two or more variables, when each of the variables
receives an increment. The total differential of the
function is the sum of all the partial differentials.

differential backup
(foldoc) | differential backup
A kind of backup that copies all files
that have changed since the last full backup. Each
differential backup will include all files in previous
differential backups since the full backup so to restore a
version of a file, you only need to search the full backup and
the relevant differential backup.
Some systems support differential backup by associating an
"Archive" flag with each file and setting this flag whenever
the file is modified to indicate that it should be included in
the next backup. A differential backup does not change this
flag, whereas an incremental backup resets it.

differential driver
(foldoc) | differential driver
An electronic device (commonly an {integrated
circuit}), containing two amplifiers, used to drive a
differential line.
(1995-03-14)
|
differential line
(foldoc) | differential line
A kind of electrical connection using two wires,
one of which carries the normal signal (V) and the other
carries an inverted version the signal (-V). A differential
amplifier at the receiver subtracts the inverted signal from
the normal signal to yield a signal proportional to V. This
subtraction is intended to cancel out any noise induced in the
wires, on the assmption that the same level of noise will have
been induced in both wires. Twisted pair wiring is often
used to try to ensure that this is the case.
The two wires might be connected at the receiver to separate
analogue to digital converters and the subtraction performed
digitally.
The RS-422 serial line standard specifies differential
drivers and receivers, whereas the earlier RS-232 standard
does not.
Opposite: single ended.
