In 1996 he was awarded the Lakatos Award in the philosophy of science for the two-volume collection of papers, The Search for a Naturalistic World View, spanning his career up until 1992. He is best known for his work in developing the CHSH inequality, an empirically testable form of the Bell inequality, also known as Bell's theorem. In the period after 1992, he proposed a geometric measure of quantum entanglement and, along with Gregg Jaeger and Michael Horne, discovered two novel complementarity relations involving interferometric visibility in multiparticle quantum interferometry. He is also known for his inquiry into the question of the "peaceful coexistence" of quantum mechanics and special relativity. He has written numerous books and research articles on the foundations of quantum mechanics and related topics. Shimony is credited with the phrase "passion at a distance" to characterize the various phenomena described by quantum correlations.
