Mike,
Interesting article how they pull mountaineering into it. It doesn't sound like some of the mountaineers I know.
'What we found,' Emilia La Nave, principal author on one of the papers, 'is that how molecules diffuse through super-cooled liquid depends upon the way energy is distributed throughout the liquid - its 'energy landscape'.'
'A useful analog,' she continues, 'is a drunken mountaineer amidst a large and confusing mountain range trying to find his way home. Even though drunk, the mountaineer will be sensible enough to find the mountain passes and stumble through them rather than climb over each peak! The key to understanding the path of the mountaineer lies in the topology of the landscape he traverses - he picks the path of least resistance.'
Safe climbing!!
