The irony is that relying on a PDF makes you weaker. Here is a strategy used by students who get A's in graduate QM:
One of the unique strengths of this text is its deep dive into Feynman’s Path Integral formulation , which is often omitted in other standard texts like Griffiths .
Let’s be honest. You are here because you are stuck. But you must ask yourself: Do you want the grade, or do you want the intuition?
Assuming you locate a , here is a strict protocol to actually learn quantum mechanics:
: Provides detailed, step-by-step solutions organized by chapter for the 2nd edition.
