Guest guest Posted July 31, 2002 Report Share Posted July 31, 2002 For the physicists on the list, this Scientific American article may be of sone interest: <http://sciam.rsc03.net/servlet/cc?lJpDUCVEtJlpMMFHhsDJhtE0EX > SECOND LAW OF THERMODYNAMICS VIOLATED It seems that something odd happens to the second law of thermodynamics when systems get sufficiently small. The law states that the entropy, or disorder, of the universe increases over time and it holds true for large-scale systems. For instance, whereas a hot beverage will spontaneously dissipate heat to the surrounding air (an increase in disorder), the air cannot heat the liquid without added energy. But scientists predicted nearly a decade ago that small assemblages of molecules inside larger systems may not always abide by the principle. Now, Australian researchers report that even larger systems of thousands of molecules can also undergo fleeting energy increases that seem to violate the venerable law. ----------------- Dr Mel C Siff Denver, USA http://groups.yahoo.com/group/Supertraining/ Quote Link to comment Share on other sites More sharing options...
