Anomalous diffusion spreads its wings |
Anomalous diffusion spreads its wings (Aug 3)
http://physicsweb.org/article/world/18/8/8
An increasing number of natural phenomena do not fit into the relatively
simple description of diffusion developed by Einstein a century ago

An increasing number of natural phenomena are being
analysed by way of fractals, Brownian motion - for which
AE got his Nobel - being one of these.

Um... maybe it's just me, but I don't see anything here that discusses
*anomolous* diffusion- it's all about random walkers and straight-up
diffusive processes.

I agree that's one lousy abstract, based on the title.
I did find:
http://chaos.ph.utexas.edu/research/annulus/rwalk.html
I was ready to scoff, but the basic idea is only retrospectively
obvious: to consider processes which look like random walks, but
violate some classical assumption about the statistics of the steps.
