Webster's 1913 Dictionary
 
 Definition: 
\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.

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.

2. An exposition of the general or abstract principles of any
   science; as, the theory of music.

3. The science, as distinguished from the art; as, the theory
   and practice of medicine.

4. The philosophical explanation of phenomena, either
   physical or moral; as, Lavoisier's theory of combustion;
   Adam Smith's theory of moral sentiments.

{Atomic theory}, {Binary theory}, etc. See under {Atomic},
   {Binary}, etc.

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.

 
Computing Dictionary
 
 Definition: 

The consensus, idea, plan, story, or set of rules that is currently being used to inform a behaviour. This usage is a generalisation and (deliberate) abuse of the technical meaning. "What's the theory on fixing this TECO loss?" "What's the theory on dinner tonight?" ("Chinatown, I guess.") "What's the current theory on letting lusers on during the day?" "The theory behind this change is to fix the following well-known screw...."

 
Biology Dictionary
 
 Definition: In science, an explanation for some phenomenon which is based on observation, experimentation, and reasoning. In popular use, a theory is often assumed to imply mere speculation, but in science, something is not called a theory until it has been confirmed over the course of many independent experiments. Theories are more certain than hypotheses, but less certain than laws.
 
Glossary
 
 Definition: a step in the scientific method in which a statement is generated on the basis of highly confirmed hypotheses and is used to generalize about conditions not yet tested.
