This word is from The Wilderness by Samantha Harris. The word is entropy. The book cover is in the sidebar.
What is entropy? "The best way to explain it is to say that it describes the natural tendency of the universe to fall apart into disorder."
"Entropy is singularly the most interesting theory that exists, he mumbles to himself, propped in front of his drawing board at the angle, he thinks, of somebody who is always about to do something significant, but never quite does."
