“The thermodynamic depth of an object tells us that it has a history. Something happened to it that brought it out of a state it could maintain by itself, whether this state was trivial and motionless order or total chaos about which there was no more to be said than the temperature that characterized it…depth is a measure of how many surprises the object has been subjected to in its history. Depth shows that something has interacted with the world. It has changed, but it is still itself; out of balance, but not out of itself. It has known surprises in its time. But it is still here. It has marked the world, and the world has marked it.” (Tor Norretranders, The User Illusion)
