Introduction to Quantum Field Theory by Matthew Schwartz
Publisher: Harvard University 2008
Number of pages: 262
The approach I will take in this course is to emphasize that Quantum Field Theory is first and foremost a tool for performing practical calculations. In this regard, I will try to emphasize the physical problems which have driven the historical development of the field, and to show how they can be solved.
