Maybe its time to try something new such as applying category theory, of all things, to physics (of particular interest to me - the application of topos theory to the foundations of physics). I stumbled across this incipient branch of mathematical physics quite by accident while checking out the "Quantum Information Scientists of the World Unite" group on facebook.

I have yet to get to grips with this subject but it does look highly promising and very exciting. Especially when you consider that "Briefly put, a topos is a category whose structure is so rich that it is capable of modelling any situation which can even be discussed in mathematical terms." Chris Hillman

*"A Categorical Primer"*(1997). Surly this must find great application in physics.

So far I have mostly looked at the work of Bob Coecke and Andreas Doering, you may want to look at their web site: Categories, Logic and Physics

if you are really interested and a bit lost (like me) see: quant-ph/0510032, quant-ph/0506132 and quant-ph/0703060, 62, 64 and 66
