"It is a characteristic of successful theories that they provide further understanding in many different areas of the field, in elegant and unsuspected ways. As for the Standard Model, we now know the the roles of asymptotic freedom, monopoles and instantons are crucial in our present picture of quark confinement, the hadron spectrum, the scaling phenomena and jet physics. The renormalization theory allows us to reproduce the observed data on the Z and W bosons with unprecedented precision. The Standard Model, as a gauge theory with fermions and at most only one scalar, is indeed tremendously successful."
