A story (actually a sideline) in the USA Today on Thursday 07/18/02 said that in an upcoming "Physical Review Letters" journal, Australian Nat'l U researchers report that a tiny bead, one micron (0.00004 inch) across, when dragged through some liquid, broke the 2nd law of physics.
Sometimes, the report says, the liquids molecules speed up the bead instead of slowing it down, as is supposed to happen. They warn that this couold be a problem with nano-technology, since it could lead to the nano-machines running backwards.
So, with this one screw up, we throw out how many centuries of mathematical formulas & need to start fresh? I don't quite understand the problem (running backwards?) mostly because I only have a very rudimentary understanding of physics. It seems that in some ways, this is good because it allows us to look at some things (Einsteins Theory of Relativity for example) with afresh perspective.
