From Dictionary.com

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

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

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

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

Inevitable and steady deterioration of a system or society.

Does this help?

[MaxCathedral]

Yes, It does, thank you.

 

 

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

 

 

The above statements implies that everything has a beginning, and then begins to move to disorder? Yes or no? Am I reading that rignt?

[albymangles]

it doesnt necessarily imply that, only that any changes in the/a system will result in more disorder for that system; for example if you have two beakers of water at different temperatures and mix them, the entropy of the system increases even though the total energy is the same, as the difference in temperature could have been used to do work. So in other words it can never decrease, although it can stay the same.
