Statistical Field Theory: From Brownian Motion to Renormalization and Lattice Gauge TheoryA comprehensive and timely survey of the application of the methods of quantum field theory to statistical physics, a very active and fruitful area of modern research, is provided in two volumes. The first volume provides a pedagogical introduction to the subject, discussing Brownian motion, its anticommutative counterpart in the guise of Onsager's solution to the two dimensional Ising model, the mean field or Landau approximation, scaling ideas
