Introduction to Quantum Mechanics

Very well explained didactically, without losing math rigor

not only does this book explain the principles of quantum mechanics in a very clear and in-depth manner, it's also very handy to get cockroaches on your dorm room floor

After going about many QM books, this is the easiest one to beging and refresh you knowledge.. Others are "too smort". Seriously thought, most books over complicate the initial topics, while this one is a delight to read and very clear.

Introduction to Quantum Mechanics, along with Griffiths’ other magnificent piece: Introduction to Electrodynamics; together, are two of the best undergraduate textbooks available. Professor Griffiths’ approach in this one is pretty mathematical, though he doesn’t ever sacrifice conceptual reasoning for mathematical sophistication. Everything he says is perpetuated with concise explanations and purpose. What I find most remarkable is how Griffiths’ seems to know the reader personally; offering derivations or further explanation at the perfect time. The problem sets are not easy, for the most part. There is hardly any hand-holding, and solutions to the problems (written by Griffiths himself) are available online as PDFs. As the third edition of this text, it is very modern. There is no worry of stumbling across outdated information. The overall visual presentation is pretty standard, but clean. The diagrams are always very helpful. The one (albeit minor) complaint I have is the deficit of example problems. There is usually only one per section, and I think some sections could certainly use more. Regardless, I would recommend this book to anyone with a foundation of multivariable calculus, some DE, and— of course— the classical mechanics prerequisite. It would probably be a good idea to know your vector calculus as well as electrodynamics.

I love this textbook! It’s a great introductory resource, I used this for my undergraduate Quantum Mechanics course. Definitely brush up on your math before hand, especially integrals and linear algebra, but the book does a great job of describing what it’s doing and how the proofs work. My only problem is the shipping and packaging. This book came very fast and on time, but there was no protective packaging in the box or anything to prevent damage during the shipping process. So, my copy did have a bit of wear on the cover. It wasn’t anything drastic that I felt I needed to return, but please be aware if you order a new copy.

The pages all seem to be in good shape but the whole book has a bit of a curve, especially the front cover. Not bad enough that I need to return since its needed for classes but still not the most pristine, given that its brand new.

This book is very suitable as a textbook, but its writing style is not suitable for self-study. It needs to combine with the teacher's detailed formula deduction in the classroom to compliment the author's lack of deduction details, but this does not affect the value of this book as an introduction to beginners. This book is consistent in spirit in the deduction of harmonic oscillations and angular momentum, and at the same time has a good explanation of Dirac notation. This is of great help to students who study quantum chemistry but want to further understand quantum mechanics. Traditionally, quantum chemistry is more focus on wave functions than matrix mechanics, but the principles of molecular spectroscopy and the application of computational chemistry (such as NMR and DFT), Dirac notation and density matrix are too important. Dirac notation is often a major obstacle for students with chemistry background. It is recommended to read with R. Shankar's book.

Todo OK y a tiempo

ottimo libro di Fisica

BUEN LIBRO

Damaged book

The textbook is an easy read while covering in a certain depth such a famously difficult subject. The theoretical explanations are short and to the point and the mathematical concepts are explained perfectly well, without taking the reader's focus away from the physical interpretation. The exercises are quite challenging but solving them supplements the understanding in a beautiful way and gives a good feeling of satisfaction of one's progress. Highly recommend it!

Some dry humor inside. Just brush up on how to read different mathematical notations and you are probably good to go. Remember to note down what each variable represents to prevent symbol/information overloads in case you forget. Becomes very useful when you progress further into the book.
