Entropy

What do we mean by entropy?

For a closed thermodynamic system, a quantitative measure of the amount of thermal energy not available to do work. noun

A measure of the disorder or randomness in a closed system. noun

A measure of the loss of information in a transmitted message. noun

The tendency for all matter and energy in the universe to evolve toward a state of inert uniformity. noun

Inevitable and steady deterioration of a system or society. noun

In physics: As used by Clausius, the inventor of the word, and others, that part of the energy of a system which cannot be converted into mechanical work without communication of heat to some other body, or change of volume. noun

As used by Tait and others, the available energy; that part of the energy which is not included under the entropy in sense . noun

A certain property of a body, expressed as a measurable quantity, such that when there is no communication of heat the quantity remains constant, but when heat enters or leaves the body the quantity increases or diminishes. If a small amount, h, of heat enters the body when its temperature is t in the thermodynamic scale the entropy of the body is increased by h ÷ t. The entropy is regarded as measured from some standard temperature and pressure. Sometimes called the thermodynamic function. noun

A measure of the amount of information and noise present in a signal. Originally a tongue in cheek coinage, has fallen into disuse to avoid confusion with thermodynamic entropy. noun

The tendency of a system that is left to itself to descend into chaos. noun

(communication theory) a numerical measure of the uncertainty of an outcome noun

(thermodynamics) a thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work noun

Strictly thermodynamic entropy. A measure of the amount of energy in a physical system that cannot be used to do work.

A measure of the disorder present in a system.

The capacity factor for thermal energy that is hidden with respect to temperature http//arxiv.org/pdf/physics/0004055.

The dispersal of energy; how much energy is spread out in a process, or how widely spread out it becomes, at a specific temperature. https//web.archive.org/web/20060702234316/http://www.entropysite.com/students_approach.html

A measure of the amount of information and noise present in a signal.

The tendency of a system that is left to itself to descend into chaos.

In its simplest sense, the tendency for all things to go from order towards disorder. It is like the one way sign for energy flows in this Universe. Urban Dictionary

Josiah Willard Gibbs (1839-1903), US physicist and absolute genius, described entropy as mixed-up-ness. The more mixed-up something is, the more entropy it has. Urban Dictionary

1.)all organic matter breaking down, even as you read this; and, yes, you're breaking down too, doesn't it feel great? :) 2.) a rocking motherfucking song off of Bad Religion's Against The Grain album Urban Dictionary

Entropy is the surface area of sound. Urban Dictionary

Chaos misunderstood. People just don't know any better Urban Dictionary

Hidden somewhere in the Chemistry Goddess' classroom. May luck be with you that you find it. Life without entropy is like life all Tuesdays. useless and horrible. Urban Dictionary

Physics aside, the inevitable and steady deterioration of any system or society. Urban Dictionary

The degradation of the matter and energy in the universe to an ultimate state of inert uniformity Urban Dictionary

A unpredictable woman with a heart of gold. Although she may be caring and wholesome, don’t think this woman cannot hold their own and roast you harder than an incinerator. Urban Dictionary

ENTROPY is a clothing brand new that exemplifies exactly what the word means: random. Created in Puerto Rico by Guillermo Cummings. Its use of vibrant colors, abstract art and influences raging from surfing to rock eNTROPY garners the attention of all who want to wear something different and look good at the same time. for more information look entropy over facebook.
