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.
The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life. Sean M. Carroll
Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy. Vaclav Havel
Venice is the perfect place for a phase of art to die. No other city on earth embraces entropy quite like this magical floating mall. Jerry Saltz
Once everyone is connected to everyone and everything else, nothing matters anymore. If everyone in the world is your Facebook friend, then why have any Facebook friends at all? We're back where we started. The ultimate complexity is just another entropy. Douglas Rushkoff
