Question: I look for a book/resource which display the general idea of the proof of Fermat last theorem in a simple manner for the public.

I mean, books which is not for mathematicians but for the general public. Books like:

> 
> *Gödel's Theorem: An Incomplete Guide to Its Use and Abuse* by Torkel Franzén
> 
> 
> 

Do anyone now any books of this kind? Also, articles or any resources are good.

Answer: 
The Epilogue in Ribenboim's book *Fermat's Last Theorem for Amateurs* is about the closest you'll get, I think. Of course, it still requires some mathematical skill just to hang with the "overview" — but, as Prometheus pointed out, you can't talk about FLT without using "real math".

For the record, the whole Ribenboim is a great book.
Two books which *might* be what you're looking for (haven't read them myself) are [*Invitation to the Mathematics of Fermat-Wiles*](http://books.google.de/books/about/Invitation_to_the_Mathematics_of_Fermat.html?id=W1Nso5E6G3YC&redir_esc=y) by Yves Hellegouarch and the 3rd edition of [*Algebraic Number Theory and Fermat's Last Theorem*](http://books.google.de/books/about/Algebraic_Number_Theory_and_Fermat_s_Las.html?id=PIibasv45boC&redir_esc=y) by Ian Stewart and David Tall.
