  We will try to sketch Professor F. Y. Wu's contributions in lattice
statistical mechanics, solid state physics, graph theory, enumerative
combinatorics and so many other domains of physics and mathematics. We will
recall F. Y. Wu's most important and well-known classic results and we will
also sketch his most recent researches dedicated to the connections of lattice
statistical mechanical models with deep problems in pure mathematics. Since it
is hard to provide an exhaustive list of all his contributions, to give some
representation of F. Y. Wu's "mental connectivity" we will concentrate on the
interrelations between the various results he has obtained in so many different
domains of physics and mathematics. Along the way we will also try to
understand Wu's motivations and his favorite concepts, tools and ideas.
