We explain how the string spectrum in flat space and pp-waves arises from thelarge $N$ limit, at fixed $g^2_{YM}$, of U(N) ${\cal N} =4$ super Yang Mills.We reproduce the spectrum by summing a subset of the planar Feynman diagrams.We give a heuristic argument for why we can neglect other diagrams. We alsodiscuss some other aspects of pp-waves and we present a matrix model associatedto the DLCQ description of the maximally supersymmetric eleven dimensionalpp-waves.Comment: 36 pages, 5 figures. v3: minor typos corrected, references adde
