dissipation

I believe that Gaston Cleric narrowly missed being a great poet, and I have sometimes thought that his outbursts of imaginative talk were fatal to his poetic gift. He squandered too much in the heat of personal communication. How often have I seen him draw his dark brows together, fix his eyes upon some object on the wall or a figure in the carpet, and then flash into the lamplight the very image that was in his brain.

Energy has a way of dissipating, you know; what can be done when you're eleven can often never be done again.

It is very desirable to have a word to express the Availability for work of the heat in a given magazine; a term for that possession, the waste of which is called Dissipation. Unfortunately the excellent word Entropy, which Clausius has introduced in this connexion, is applied by him to the negative of the idea we most naturally wish to express. It would only confuse the student if we were to endeavour to invent another term for our purpose. But the necessity for some such term will be obvious from the beautiful examples which follow. And we take the liberty of using the term Entropy in this altered sense ... The entropy of the universe tends continually to zero.
