Hi and welcome to the first episode in my new series on quantum field theory! In it, I will derive some beautiful results from quantum field theory, building up from 0 dimensional quantum fields and assuming only a background in calculus. If you have any questions, comments or critiques, please let me know in the comments below. I based this video series on the fantastic textbook "Quantum field theory: A diagrammatic approach" by Ronald Kleiss, which I highly recommend getting yourself if you are interested in studying the subject.
