the author brain greene claims that the equations of string theory are not known, only perhaps some properities asserted.

which i suppose is one of the many things separating string theory from quantum physics and relativity, both of which have fairly simple equations, although it takes some training in mathematical formalism to use them, and in most cases it takes computational resources to derive answers from analytical results that can't be 'closed.'

which sorta reminds me of one of the interesting elements of physics: just as experimental measures involve uncertainty, mathematical predictions can as well. as a simple example, resolving the...idea...of sqrt(2)into a (rational) number implies a range. you might say it's between 1.414 and 1.415. with more computational resources you can narrow the range arbitraility, but as computational resources are fininte this can be a problem in difficult calculations.
