Title: The worst text-book on theoretical physics I ever read
Review: This book is simply awful.I couldn't understand a lot of derivations.Before buying this book I studied the standard course on QFT by Peskin and Schroeder.(I solved 95% of its problems, so I'm not stupid!).The reason I bought the book by Itzykson and Drouffe was to study some interesting advanced topics in QFT.I began with Ising model and immediately got stuck.I read previous reviews on this book. The authors praised it.I wonder if any of them could proceed from formula 65 to 66?(first volume)Did any of them understand the derivation of Szego lemma?What about Kac determinant?I found that even original article by Itzykson was written betterand with more care than this book.(!)Still it's worth buying as the source of references.That's why one *.
Is the review positive or negative?
