string theory ?

[1123581321]

I was wondering whether string theory unifies the other forces via symmetry or fields

 

i've been reading on it and have become a little confused.

 

also would someone be able to explain to me what generalisation (of an equation) means.. in non technical terms if possible, thanks.

The particles are associated with excitations of the string (first quantisation). One can then describe these particles in a low energy limit via a field theory. Indeed this is how field theory should arise in the context of strings.

A generalisation of a mathematical object is some other object that contains the original object as some specialisation or limit, or otherwise keeps some of the properties of the original object.

 

This is quite lose and generalisation can mean almost anything, though it should be similar in some way to the starting object or construction.
