Mathematics and computer science: coping with finiteness

By presenting these examples, I have tried to illustrate four main points. 1) Finite numbers can be really enormous, and the known universe is very small. Therefore the distinction between finite and infinite is not as relevant as the distinction between realistic and unrealistic. 2) In many cases there are subtle ways to solve very large problems quickly, in spite of the fact that they appear at first to require examination of too many possibilities. 3) There are also cases where we can prove that a fairly natural problem is intrinsically hard, far beyond our conceivable capabilities. 4) It takes a good deal of skill to decide whether a given problem is in the easy or hard class; but even if a problem does turn out to be hard there are useful and interesting ways to change it into one that can be done satisfactorily.

Physics/computer science. Passing messages between disciplines

Problems in computer science, such as error correction in information transfer and "satisfiability" in optimization, show phase transitions familiar from solid-state physics. In his Perspective, Mézard explains how recent advances in these three fields originate in similar "message passing" procedures. The exchange of elaborate messages between different variables and constraints, used in the study of phase transitions in physical systems, helps to make error correction and satisfiability codes more efficient.
