Theory \The"o*ry\, n.; pl. Theories. [F. th['e]orie, L.
theoria, Gr. ? a beholding, spectacle, contemplation,
speculation, fr. ? a spectator, ? to see, view. See
Theater.]
1. A doctrine, or scheme of things, which terminates in
speculation or contemplation, without a view to practice;
hypothesis; speculation.
[1913 Webster]
Note: ``This word is employed by English writers in a very
loose and improper sense. It is with them usually
convertible into hypothesis, and hypothesis is commonly
used as another term for conjecture. The terms theory
and theoretical are properly used in opposition to the
terms practice and practical. In this sense, they were
exclusively employed by the ancients; and in this
sense, they are almost exclusively employed by the
Continental philosophers.'' --Sir W. Hamilton.
[1913 Webster]
2. An exposition of the general or abstract principles of any
science; as, the theory of music.
[1913 Webster]
3. The science, as distinguished from the art; as, the theory
and practice of medicine.
[1913 Webster]
4. The philosophical explanation of phenomena, either
physical or moral; as, Lavoisier's theory of combustion;
Adam Smith's theory of moral sentiments.
[1913 Webster]
Atomic theory, Binary theory, etc. See under Atomic,
Binary, etc.
[1913 Webster]
Syn: Hypothesis, speculation.
Usage: Theory, Hypothesis. A theory is a scheme of the
relations subsisting between the parts of a systematic
whole; an hypothesis is a tentative conjecture
respecting a cause of phenomena.

Binary \Bi"na*ry\, a. [L. binarius, fr. bini two by two, two at
a time, fr. root of bis twice; akin to E. two: cf. F.
binaire.]
Compounded or consisting of two things or parts;
characterized by two (things).
[1913 Webster]
Binary arithmetic, that in which numbers are expressed
according to the binary scale, or in which two figures
only, 0 and 1, are used, in lieu of ten; the cipher
multiplying everything by two, as in common arithmetic by
ten. Thus, 1 is one; 10 is two; 11 is three; 100 is four,
etc. --Davies & Peck.
Binary compound (Chem.), a compound of two elements, or of
an element and a compound performing the function of an
element, or of two compounds performing the function of
elements.
Binary logarithms, a system of logarithms devised by Euler
for facilitating musical calculations, in which 1 is the
logarithm of 2, instead of 10, as in the common
logarithms, and the modulus 1.442695 instead of .43429448.
Binary measure (Mus.), measure divisible by two or four;
common time.
Binary nomenclature (Nat. Hist.), nomenclature in which the
names designate both genus and species.
Binary scale (Arith.), a uniform scale of notation whose
ratio is two.
Binary star (Astron.), a double star whose members have a
revolution round their common center of gravity.
Binary theory (Chem.), the theory that all chemical
compounds consist of two constituents of opposite and
unlike qualities.
