"Maxwell's Demon" Possibility???(Entropy) About a hundred years ago, James Clerk Maxwell imagined 2 adjacent chambers, each containing gas and both sealed to the outside world. The chambers are also sealed from one another, except for a single gate the size of a gas molecule. Guarding this gate would be an intelligence with one power: the ability to discriminate between fast and slow molecules. It would pass slow molecules in one direction only, fast molecules in the other direction only. The net result would, after a time, be one chamber that contained only slow-moving molecules, next to a chamber that contained only fast-moving molecules. In other words, the chambers would not be the same temperature: One hot and one cold. Should such a "Maxwell Demon" prove possible, its discriminatory intelligence would reverse the apparently irreversible entropy, which inevitably has everything existing at the same low temperature? Any Comments?
