Thermodynamics and geometry

It is perhaps appropriate that, in a year marking the 100th anniversary of his landmark paper in thermodynamics, new developments should call fresh attention to the special beauty and profundity of the work of J. Willard Gibbs. Recent work has proved the possibility of constructing a new representation of equilibrium thermodynamics, one that is couched in a mathematical language—an intrinsically geometrical structure—quite different from that generally employed.
