  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
     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.
            [1913 Webster] Theosoph

  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.
     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
     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.
        [1913 Webster]
