Wiener even came up with a physics-based description of how life is formed by information. Check it out. Hang in there too, it's worth it. * "Platform for Change", by Stafford Beer, 1978, ISBN 0 471 06189 1 * * The term 'entropy' began life as a subtle measure of energy flow. * * When something hotter is systemically bound to something cooler, the * greater energy of the hotter stuff migrates---inexorably migrates--- * into the cooler stuff. This is one manifestation of the Second Law of * Thermodynamics, which everyone of education has encountered. * * This is sometimes referred to as 'the universe is running down'. Okay, 'entropy', yeah I remember that kinda. Keep going: Our solar system is a lot of matter that is NOT sitting in a situation of entropy: the sun is radiating heat at the planets. Instead of just matter smoothing out to a common low-energy state, a burning fireball is at work. Cybernetics states that under conditions like this, matter does something special. * "Platform for Change", by Stafford Beer, 1978, ISBN 0 471 06189 1 * * If we have a universe, which is improbable though it exists, it is * because the Second Law of Thermodynamics has two forms. One is concerned * with the pressure to even out energy; that is the form which belongs to * our stereotyped conception of the universe. It betokens death. * * The other form is about information content, which leads to greater * organization and increasing complexity. That form betokens life. What would be a specific example of energy causing matter to be formatted by information, becoming "more complex"? * "The Human Use of Human Beings", by Norbert Wiener * * A light quantum is a very small thing, but it turns out the energy * transfer which is necessary for an effective information coupling * is quite s
