The basic resolution of the Schrodinger paradox is simple: Organisms continue to exist and grow by importing high-quality energy from outside their bodies. They feed on what Schrodinger termed "negative entropy"?the higher organization of light quanta from the sun. Because they are not isolated, or even closed systems, organisms -like sugar crystals forming in a supersaturated solution -increase their organization at the expense of the rise in entropy around them. The basic answer to the paradox has to do with context and hierarchy. Material and energy are transferred from one hierarchical level to another. To understand the growth of natural complex systems such as life, we have to look at what they are part of?the energy and environment around them. In the case of ecosystems and the biosphere, increasing organization and evolution on Earth requires disorganization and degradation elsewhere. You don't get something from nothing. www.intothecool.com/energetic.php Into the Cool blog www.intothecool.com/blog/ - synthum , posted 12/03/05 |
