Hi Pete,
I had a look at that link, and I think that would lead to a stroke at the moment
I read a few theoretical books on string theory (no maths, just text), after that I bought Polchinski's 2 book series (a nice cheap copy from ebay) and was surprised at how much maths I had forgot. I did specialist maths in VCE, but you know the old saying "if you dont use it....."
Looks like I cant find any shortcuts around it.
Thanks again for everyones input!
Cheers,
Greg
