The Principles Of Quantum Mechanics (International Series Of Monographs On Physics)

This is almost a must-have (if not a must-read) for those seriously interested in quantum matters. It was last updated by Dirac in 1967, so there are many more modern textbooks for those of the "shut up and calculate" persuasion. Aside from the cultural literacy aspect, the clarity of Dirac's writing is remarkable, and his exposition of topics such as superposition is unsurpassed. Philosophically, he believed that physics should only concern itself with observable and measurable quantities, and that the only satisfactory "picture" of what goes on at the atomic level is the mathematical formalism itself. But he delves more deeply than most authors into the basis and motivation for aspects of the formalism such as the Dirac delta, difference between the Schrodinger and Heisenberg approaches to equations of motion, etc.

This book is the basis of Quantum Mech any physicist that respect him or herself should read Dirac because it resembles the origins and gives the best description of QM there can be in this book you can feel the real possibilities of QM I say possibilities because at the time QM wasn't fully developed, or at least as thought through as it is now.Either way this is a basic book for anyone intending to study physics I really recommend it.One thing you should know is that the image given here is the not the real one, you should look at th one given by me, is one taken from the look inside, that has the real cover. But as it is always said you should never judge a book by its cover, even more so if the one who wrote it was the best physicist in the last century.

His insight into the physical interpretation of the formalism of Quantum Mechanics has no precedent. Almost every physicist around the world agrees that HE IS MASTER DIRAC, so an insight into his vision of the theory is invaluable.This is not a didactic book, in fact, in my opinion, it is not even to be considered a text book. Its value concerns the rigorous development of the formalism of QM, as well as a firm base for the understanding of the very principles of it. I'd say it's better for people who have struggling qith the ideas of QM for a while already, that for who are just starting with them.

A classical text book, although the tone is pretty dry. I would not use this as a primary undergraduate book, but appreciate its historical importance.

Anything can be added commenting a book made by one of the fathers of quantum Mechanics and many other fields of knowledge. A must for those who want to explore how to arrive to the deepest conclusions in physics. An insight on their amazing way of looking to the world...What should be best to guide through this matter than one of its creators?

My boy’s at it again.

The book was delivered in a very good condition! The price is also really reasonable.

It's the greatest text on quantum mechanics ever written ...

And not a single picture! Apparently Richard Feynmann read this book as a teenager. I am not so gifted, and am reading it at a slow pace. It is incredible how many subtle insights there are if you read the text carefully. Dirac really and deeply understood QM. The quantum mechanics book by Susskind (in the theoretical minimum series) seems to be based one-to-one on this book, but treating everything on a higher level. I am happy that I read the Susskind one in my holiday before starting the Dirac book. This is my recommendation to you if you are evaluating buying this book. Highly recommended! ps. use Claude, chatgpt or just google to find help if you are stuck. Since many people struggled with this book there is a lot of info to be found!

Eu nunca havia lido esse livro antes, porque pensei que seria muito mais difícil do que estudar um texto didático clássico de mecânica quântica, como Cohen-Tannoudji (ou Griffiths, que já é praticamente um clássico, embora bem mais simples e menos completo). Eu estava muito enganado.Dirac é claro e sucinto. O estilo parece o de um autor russo, como Landau. Só que muito mais fácil de entender. Dirac claramente quis escrever o texto mais acessível que poderia sobre o assunto (isso definitivamente não significa que o texto é acessível para o público em geral, é preciso saber cálculo e álgebra linear, no mínimo, e muito bem!).É um clássico, com razão. E se estás começando a estudar quântica, vale muito a pena ler esse livro antes ou concomitantemente a outros livros (algumas derivações, como a relação entre as bases q e p, <q|p>, só encontrei aqui).

The Dirac formalism is not an easy to read, requires a lot of practice, but a very efficient framework of the topic. Dirac did a really great job with this book to give the formal definition for the algebra of quantum mechanics with its application to several problems. It is a book for those who are familiar with the topic and related mathematics and would like to put it onto a concise formal theoretical next level.

Il grande classico (da acquistare in inglese) dell'eccelso fisico Dirac noto per la sua equazione in Teoria dei Campi Quantistici è il modo decisamente migliore per approcciare alla MQ per studenti ma anche appassionati di fisica. Le spiegazioni lunghissime dei fondamenti della meccanica dei quanti unite all'introduzione al formalismo braket e alla quantizzazione delle coordinate canoniche chiariscono effettivamente moltissimi dubbi, costruendo una impalcatura a posteriori (1930) della teoria sviluppata negli anni '20.Per approcciarlo sono utili buone basi di fisica in quanto il libro in sé non ritorna sui concetti classici, così come sul formalismo hamiltoniano, per cui non è pensabile approcciare il libro da zero per chi fosse un amatore. Non è ovviamente molto aggiornato rispetto alla didattica contemporanea e può quindi essere utile integrarlo con qualche altro testo più aggiornato come il Sakurai o altri testi di una didattica più recente.Senza dubbio uno dei libri della mia biblioteca di fisica più affascinanti e ben congegnati, come del resto ci si poteva aspettare da Dirac.

Je recommande fortement ce livre pour tous les physiciens qui s'intéressent à la mécanique quantique
