Order is found in things working beneficially together. It is not the forced condition of neatness, tidiness, and straightness all of which are, in design or energy terms, disordered. True order may lie in apparent confusion; it is the acid test of entropic order to test the system for yield. If it consumes energy beyond product, it is in disoder. If it produces energy to or beyond consumption, it is ordered.
