Edwards' work in condensed matter physics started in 1958 with a paper[REF] which showed that statistical properties of disordered systems (glasses, gels etc.) could be described by the Feynman diagram and path integral methods invented in quantum field theory.
The Doi-Edwards theory of polymer melt viscoelasticity originated from an initial publication of Edwards in 1967[REF], was expanded upon by de Gennes in 1971, and was subsequently formalized through a series of publications between Edwards and Masao Doi in the late 1970s [REF].
