While AGD is famously dense, FW is celebrated for its clarity. The book is structured into two distinct parts, making it a complete course in the subject:

Fetter and Walecka focuses heavily on analytical methods (pen-and-paper derivations). Modern researchers frequently implement these equations computationally. You can supplement your reading by writing simple Python or MATLAB scripts to numerically solve the Hartree-Fock equations or calculate the RPA dielectric function described in the text. 2.
