5.0 von 5 Sternen This fills in a gap., 14. Juni 2014
Rezension bezieht sich auf: Quantum Field Theory for the Gifted Amateur (Taschenbuch)
In my opinion, this book fills a gap.

The problem when you want to start learning QFT and do not attend, for instance because you specialize in a more experimental section, a lecture, you find yourself being overwhelmed by the amount of literature available on the subject. The level of sophistication of the sevearl textbooks differs - a good starting point is in my eyes still Griffiths: Introduction to Elementary Particle Physics, which enables you to bulge through some cross-section calculations and model f.i. massive photons in the exercises. Afterwards, stuff like Aitchinson Hey should have become accessible to read, and ponder exercisewisely. However, both texts could provide the image of QFT being only applied in particle physics, which is certainly not true. In fact, several applications from condensed matter physics aid more pedagogically for understanding stuff better - renormalization group methods are in my eyes better explained in statistical physics than directly in quantum field theory. Also, some of the condensed matter physics applications were more graspable to me in the first place - but this of course highly subjective.

Furthermore, other books usually proceed traditionally via the canonical quantization approach. This is pedagogically in order, but the path integral approach gives you handy methods for calculating and devising some cool models.

In fact, the book is in principle what it claims to be - quantum field theory, and not only (not to be misunderstood as pejorative) QFT merged with particle physics.

About the contents of the book itself. I particularly like the inclusion of a "wisdom from statistical physics" part, for reasons that I have given before. Secondly, the short, but very clear treatise on QFT for spin-1/2's with a photon field (QED) is very nicely written - and not too long! Personally, I have always found that the calculation of cross sections, and only QED stuff is not so motivational for students like me. Rather, giving directly path-integral methods and actually showing the applicability of QFT not only in the form of QED is very helpful.

The later sections, for instance the treatments of YM-theory, Instantons, Dirac-Monopoles in the realm of particle physics is thin - but I consider this to some extent as an advantage because, unless you are specializing in theoretical particle physics for instance, you would not be in need for all the technicalities that occur there. The person interested in some of the more technical details (in particle physics) can for instance consult Schwartz' QFT book, which I prefer above Peskin a bit. For Condesend Matter applications, the classic reference is the Altland-book. If you want to enjoy some equation checking and quickly proceed to String theory and stuff the traditional way (leanign towards concepts, not so mich calculations), I'd recommend to you Kaku's QFT (beware of typos), who contains some interesting exercises (not every one, but yeah).

As for the mathematical background, I would, anyway support comforting yourself with Hassani-books, or, if you are german-speaking, the Goldstein or Fischer-Kaul series is also very helpful. To get a feeling what the guys from mathe-department prove all-day-long, you can read and do some of the exercises of Storch-Wiebes 4-volume tome (~3500pp.) "Lehrbuch der Mathematik". You could deepen your understanding especially of topology by consulting Nakhara, Frankel (I only partially recommend this book) or, my favorite, Bo-Yuan, which should, nonetheless be read after Nakahara.

The lack of solutions to problems is quite normal, and I would to some extent consider it not necessarily as a problem. In general, I use more than one book for learning a subject, and sometimes, some of the more difficult exercises can be found in other books worked out as part of the theory.

Sometimes, even knowing that solutions to exercises, proofs to theorems exist can have its own value.

4.0 von 5 Sternen Should be a beginner's text!!!, 27. Mai 2014
Verifizierter Kauf(Was ist das?)
Rezension bezieht sich auf: Quantum Field Theory for the Gifted Amateur (Taschenbuch)
This book needs to be studied right after the final undergraduate year.
The presentation is very clear but still as far as the mahematics of functional analysis is concerned, i think it needs more concrete example and relevant number of exercices to equip the enthusiast with much confidence.
the first chapter coould be a bit bigger to accomodate more functional concpets.
The overall idea is to convey in concise manner the exciting techniques of the exciting field of QFT.
the drawback is that at some places the injustice is done to the mathematical exposition especially in the later chapters such as propagator and greens function...one needs to be good in statistical and quantum mechanics appreciably to sail through the book.
Physical expositions behind the formulae in QFT is very very mind grabbing...
Just loved reading it...but could have been better if we had the solutions to the problems were given at the back of the book.
...worth every penny spent!

5.0 von 5 Sternen An eye opener, 21. Dezember 2014

Rezension bezieht sich auf: Quantum Field Theory for the Gifted Amateur (Taschenbuch)
My studies of physics are just a faint memory.. But there was always the nudge to try to understand it better. I concede that this book is no easy reading. But it is extremely rewarding to "see the light" a little brighter after each chapter. How nice to see things evolve using mathematics explained on relatively basic principles. Extraordinary!

5.0 von 5 Sternen pädagogisch sehr gutes Buch, 17. Juni 2014
Verifizierter Kauf(Was ist das?)
Rezension bezieht sich auf: Quantum Field Theory for the Gifted Amateur (Taschenbuch)
Ich sehe mich selbst, so wie der Buchtitel es ausdrückt, als "Gifted Amateur"
und finde, daß die einzelnen Facetten dieses Gebietes jeweils beispielartig und prägnant dargestellt sind, im Gegensatz zu
manchen anderen Büchern, die ebenfalls Lehrbuch-Charakter beanspruchen.
