"That's the trap," Sarah warned. "The manual tells you the destination. Your job is to understand why the path was built that way. If you just copy the trace theorems, you’re a calculator. If you understand why the trace of an odd number of gamma matrices is zero, you’re a physicist."
To avoid turning the manual into a crutch, follow these best practices: "That's the trap," Sarah warned
The heart of the book. Problems require calculating matrix elements, spinors, and traces of gamma matrices. The solutions manual is invaluable here because it: "That's the trap
