Molecular chip promises much

The problem with nano-miniaturisation is that the laws of physics get more chaotic the smaller you go. At the atomic level quantum physics reigns, and we don't really understand it very well - probably because its so freakishly weird. Anyone read the article on the same site about nanorobots that are so small that engines modeled for them using normal physics would run backwards? :-D

Logic is a nice thing that exists when you're talking about big things like people and trucks. At the subatomic level, it collapses into a foamy multidimensional structure. Motors designed using classical physics running backwards was just one of the side effects. It's all to do with chaos theory and enthalpy I think - way, way over my head.

They say that self-awareness may also be a side effect of quantum processing (!).

Anyway, here's the link:
