One of the authors, John Baez, has been blogging since before the concept existed. If you're interested in these kinds of topics his _This Week's Finds in Mathematical Physics_ is an amazing resource -- even more amazing that it's usually accessible to those of us who aren't professional physicists.<p><a href="http://math.ucr.edu/home/baez/TWF.html" rel="nofollow">http://math.ucr.edu/home/baez/TWF.html</a>
Oh great, now my brain hurts. Does anyone know of any papers mapping cryptography to category theory? It seems that there could be some interesting results of such a thing, even if it is just reasoning about security protocols in terms of string diagrams.
One of the authors, Baez, wrote "Gauge Fields, Knots, and Gravity" a lovely, cheap, and fairly accessible intro to applications of topology in mathematical physics. Worth a glance if you find yourself wondering about all this
