Entropy, the tendency of everything to fall apart (or tend to a lowest-energy state) is a topic that fascinated Smithson (crystal works, Glue pour, Partially-Buried Woodshed) and Morris. The reversal of entropy is the most convincing definition I have ever heard for something being alive; for a limited time life brings matter together, resists disintegration, and heals itself if it is damaged. Sound is (as I recall) often quoted as a example of the opposite, entropy in action; the sound waves propogate until they disappear, and their energy is ‘lost’ (actually converted to other lower forms of energy). There is perhaps something interesting here, a dissipation.
