Stephen Wolfram in 2002 published a 1300 page tome "A new kind of science" trying to prove...hem...what was it that he tried to prove? :-) I am joking of course! The NKS book is fantastic and well worth studying. You can now read it online for free, but I still enjoy my splendidly crafted printed version. Also, the Principia is indeed a large 3 volume opus, but the 1+1=2 proof is relatively short as you can see here: http://en.wikipedia.org/wiki/Principia_Mathematica#Quotations The proof in Theorema that 1+1=2 is fully automatic (once you write the axioms of arithmetic), is short and quite readable.
