"Starting in the late 1960s and then accelerating in the 1970s, our optimism about quantum field theory once again returned with the advent of the Standard Model — first of electromagnetic and weak interactions and then chromodynamics for the strong interactions. And quantum field theory became the tool of choice for doing calculations in particle physics."
