Where does BornInfeld theory emerge from?How can one obtain/derive its lagrangian action?And most importantly,what does it describe??

I've been in Dubna last year for about a month.I had alist of about 7 books on superstrings,and, the only one in Enlglish i found at the "Bogoliubov Laboratory of Theoretical Physics" was the one written by Lars Brink and Marc Henneaux "Principles of string theory".Havind just read Dirac's book"Principles of QM",i thought "It can't be that difficult".I opened the book and never got beyond the first page where lied only one formula:the BornInfeld action.Obviously,having no idea abot that thing,i found no point in reading the next pages.
Satisfied with my answer?

The borninfeld action governs the dynamics of higher dimensional objects called Dbranes. Over the last decade they've helped reveal a great deal about nonperturbative aspects of string theory and in particular that what appeared to be many different theories are actually different backgrounds of a unique theory called Mtheory. But to understand Dbranes one must first learn the basics of string theory since Dbranes first appear, in connection with a symmetry known as Tduality, as surfaces on which open strings end.

Thanks for setting things straight,man.
