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.
Software is like entropy. It is difficult to grasp, weighs nothing, and obeys the second law of thermodynamics; i.e. it always increases. Norman Ralph Augustine
Consciousness, when it's unburdened by the body, is something that's ecstatic; we use the mind to watch the mind, and that's the meta-nature of our consciousness; we know that we know that we know, and that's such a delicious feeling, but when it's unburdened by biology and entropy, it becomes more than delicious: it becomes magical. Jason Silva
An egg is a beautiful, sophisticated thing that can create even more sophisticated things, such as chickens. And we know in our heart of hearts that the universe does not travel from mush to complexity. In fact, this gut instinct is reflected in one of the most fundamental laws of physics, the second law of thermodynamics, or the law of entropy. David Christian
