A theoretical <physicist> who, with <Philip Warren Anderson>, developed a description of <spin glasses> using an <order parameter> based on persistent local-spin correlations. A material can lack a net <magnetization> while individual spins retain memory of their orientation. Edwards's own account connects this problem with ideas from disordered polymer networks and explains the use of replicas in calculating thermodynamic behavior.<Citation Classic commentary on Theory of spin glasses by Sam Edwards>[p. 20: local-spin memory, polymer-network analogy and replica method]{ref}
