Defining Life in Three WordsJanuary 13, 2012
“Pushing against entropy”
A slightly longer version to clarify what I’m getting at: “Life is a property of a system whereby it increases the entropy of its environment so as to lower the entropy within the system itself.”
Alex's comment: The best definition of life I've ever seen!
生命的定義：「生命」是一個物理系統中的一種特性，它透過提高系統外環境的熵（亂）以降低系統內的熵。
引申：人是動物，動物是生物，生物是物理系統；人是物理系統。
