Freebase

  1. Theory

    Theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several different related meanings. A theory is not the same as a hypothesis, as a theory is a 'proven' hypothesis, that, in other words, has never been disproved through experiment, and has a basis in fact. One modern group of meanings emphasizes the speculative and generalizing nature of theory. For example in the arts and philosophy, the term "theoretical" may be used to describe ideas and empirical phenomena which are not easily measurable. And by extension of the philosophical meaning, "theoria" is also a word still used in theological contexts. As already in Aristotle's definitions, theory is very often contrasted to "practice" a Greek term for "doing", which is opposed to theory because pure theory involves no doing apart from itself. A classical example of the distinction between theoretical and practical uses the discipline of medicine: medical theory involves trying to understand the causes and nature of health and sickness, while the practical side of medicine is trying to make people healthy. These two things are related but can be independent, because it is possible to research health and sickness without curing specific patients, and it is possible to cure a patient without knowing how the cure worked.

The New Hacker's Dictionary

  1. theory

    The consensus, idea, plan, story, or set of rules that is currently being used to inform a behavior. This usage is a generalization 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....”

  2. Kelly Miller:

    Because Titan is the only moon in our solar system with a substantial atmosphere, scientists have wondered for a long time what its source was, the main theory has been that ammonia ice from comets was converted, by impacts or photochemistry, into nitrogen to form Titans atmosphere. While that may still be an important process, it neglects the effects of what we now know is a very substantial portion of comets: complex organic material.

The subconsciousness crawls out at times and controls consciousness. We do what we want to do subconsciously. And we act unconsciously. And the subconscious is an audio tape of memory. We subconsciously remember what we knew in past lives and repeat some things in this one. Memory tape records everything we thought and what we think about. Also with videotape that periodically displays deja vu. Memory controls our subconscious actions and can tell us what we should say in this case. This tape contains all our life experiences of all our lives. Author: Musin Almat Zhumabekovich
