Advanced quantum field theory, Lecture 1

*UPDATE*: Alexander St. John has begun writing notes for the course. They are available at https://github.com/avstjohn/advanced_qft.git This summer semester (2017) I am giving a course on advanced quantum field theory. This course is intended for theorists with familiarity with advanced quantum mechanics, statistical physics, and quantum field theory (for a good foundation see my videos on advanced QM and QFT). The main objective is discuss the building blocks of the standard model, including, Yang-Mills theory and symmetry breaking. Here in Lecture 1 I discuss path integrals.
