Introduction to Quantum Mechanics

Introduction to Quantum MechanicsBy David J. GriffithsFirst Edition, HardcoverSize (Roughly): 24 x 17 x 3 centimeters.Book sold by "1UP Video Games, Books & DVDs" on Amazon.Announced in "Acceptable" condition with the next description: Foxing and spots on side of book.\The book is in excellent condition, would buy again from this seller.Griffiths is a known author by many physicist around the world, consider by many as the best introductory book on quantum mechanics for an undergraduate student. The true is, there is not a correct answer, and there are plenty of books out there that might be a better option to any of you.Also, you need to understand there is not one book in any topic that'll teach all there is to a subject. In quantum mechanics different references are needed to understand the different interpretations there exist.There are some things that this book does great, and it is teaches you why the wave equation is important in QM. The first equation is Schrödinger equation, with not a try to formulate this or to justify its particular form.On the second chapter it solves the classical examples, which are particular cases where the Schrödinger equation has an analytical set of solutions. It's on chapter 3 where there's some formalism. Chapter 4 is on quantum mechanics in 3 dimensional systems and how you write the mention equation in spherical coordinates. This is applied to the Hydrogen Atom and has a brief discussion on angular momentum in QM. And to conclude the first part there's chapter 5 on identical particles and the easiest of this systems is a two particle system.The second part of this text it's on applications, starting with time independent perturbation theory which is a common method applied to approximate solutions to Schrödinger's equation. Chapter 7 covers the variational principle an alternative method applied to the study the ground state of a system. Then there is the WKB (Wentzel-Kramers-Brillouin) Method, time dependent perturbation theory and the adiabatic approximations, the final chapter goes into the basis of scattering.This book is lacking the formalism of Dirac that is fundamental in Quantum Field Theory, particle physics or even Quantum Mechanics at the graduate level. There's nothing on Heisenberg's picture of Quantum Mechanics. A good book, but not a stand alone to study quantum mechanics, you'll 100% need another reference to complete this one.

I’m young and trying to get into Quantum Mechanics and this book is fantastic.. it explains things in the easiest way to understand. But don’t be fooled.. while it is an amazing book it is not for fresh beginners. It does have some advanced thinking requirements and complex math. But over all amazing book 10/10 highly recommend.

The book was in good shape. I believe I had ordered "Very Good".As for the book itself, it's well written and easy to follow. I have no mathematical experience in quantum mechanics (but I do have some high level college math under my belt), only what I've read in books about cosmology which is why I bought this book to understand why physicist procure the ideas they do about the cosmos. Obviously a text book, but great for nerds like me.

This is the best undergraduate quantum mechanics book I have ever read. Every undergraduate program should be using this book, the other books I've seen don't even come close. That includes Liboff, Goswami, and Greiner.I even think this book is worth a read after going through Cohen-Tannoudji. While the other books leave the student confused, with their heads spinning, Griffiths uses his excellent ability to explain things to provide as clear an introduction to the subject you could imagine. I disagree with the other reviewers, the notion that Davies book is better is absurd. As far as the problems with the examples, I think Griffiths approach is a good one.

The simplest clearest introduction to Quantum Mechanics I have ever read, I only wish my professors had told me about this book when I studied physics. Every book by David Griffiths is a "must have" if Physics is your obsession.

This takes a very statistics-like approach. Also, it just breezes over pretty much everything. I would not recommend; I feel there are better books (such as Townsend's).

Great book, well worth the money. One that other texts refer to. Great for self study

Good, I guess. I've tried different QM textbooks and Griffiths has a very special way of teaching, maybe he could've went more in detail with the mathematics or history behind quantum.

cheaper than the second edition, but completely re-written chapter 3

Tiene la información necesaria para mis estudios de la Universidad. Lo he estado he estado ocupando en mis proyectosy me ha sido de gran utilidad.
