Diagrammatica: The Path to Feynman Diagrams (Cambridge Lecture Notes in Physics)
"...a masterful introduction to quantum field theory and its application to elementary particle physics through Feynman diagrams.  The approach is constructive rather than deductive, and the book offers many fine insights into the physics content of results that may be thought of as purely mathematical."   Ernest Ma and Jose Wudka, Physics Today"...would be a useful and solid starting point for a novice field theorist..."   R. Delbourgo, Mathematical Reviews
