The path integral on the lattice is explained in concrete examples using weak and strong coupling expansions. Fundamental concepts such as the 'triviality' of Higgs fields and confinement of quarks and gluons into hadrons, are described and illustrated with the results of numerical simulations. It also provides an introduction to chiral symmetry and chiral gauge theory. «
