Covers the basics of quantum field theory, emphasizing the transition from classical to quantum descriptions and the role of fields in mediating interactions.
Introduces Quantum Field Theory as the way to reconcile Quantum Mechanics with Relativity, emphasizing the need for a local field due to the impossibility of instantaneous interactions at a distance.
Explores classical field theory, focusing on Lagrangian formulation and the Euler-Lagrange equations, emphasizing the property of locality in spacetime.
