Quantum Mechanics and Path Integrals (Dover Books on Physics)

I just got this book today, and congratulations to Dover for making this landmark text readily available for such a small price. I have the original copy, which now sells for much more money. If you can find a used copy that is, the book being out-of-print.I don't think I need to review the contents - I had read this in my student days and anyone looking at this will be aware of this text's stellar importance.What is amusing is this "emendment" by D. Styer, who says he corrected hundreds of misprints etc. But just leafing throught it, on page 164, the title of section 7-1 has a glaring misprint. I wonder what other misprint has been left if I spotted one so easily in 10 seconds ;-) Actually I need to check in the original book whether that mistake was there at all. Small things, but be coherent ...

Great approach to Path Integrals. Found it very useful starting on it before moving to QFT.

Perfect arrival and content

Thorough and pedagogic, though a bit dated. Great at explaining complex ides simply.The derivation of regular wave mechanics from path integrals is interesting, and gave me a new understanding on the laws I thought I knew so well.It's good for the basics of getting to grips with path integrals, but you should definitely seek out some more advanced, rigorous texts if you're comfortable with the simplest integrals.

great.

The concepts dealt with in the book are fascinating but the maths is hard going for a once enthusiatic physics graduate who has spent most of his life in geophysics where the sums are much easier.my 3 star rating is largely based on the Kindle edition and the fact that working through the equations is made more difficult by having several of them missing, ie an equation number with no equation.A better grasp of the mathematics used than I currently have would enhance the content greatly.I

I've almost finushed chapter 3 and so far it's excellent. Clear descriptions and clear elegant maths.I have knowledge of quantum mechanics from other books, so the basic concepts arn't new to me.

So far, so ok.The first probability example is confusing.Feynman is measuring the probability of a particle going through a hole. And then measuring the probability of the particle arriving at a subsequent screen.My lack of understanding is- the number of outcomes pre screen is enormous. So the chance of success (getting through the hole) is a small percentage. However measuring the probability of hitting the screen is a certainty. Unless a particle, post hole 🕳️ , is no longer a particle. Maybe that’s the point.Anyway, I just started reading. It can be read (it’s not in pig Latin ).I think the cover size should be larger. That way I can carry it around on my hip in a trade up NYC department store and maybe meet an interesting lady 🤷‍♂️.Thanks, now for the joke: I'm reading a book about anti-gravity. It's impossible to put down.Jim 🚶🏼Or James 🚶🏼

O livro exige um certo conhecimento prévio. Indico para quem já pagou uma cadeira de quântica além da introdução.

Great book. Really helpful for readers who want to get an indepth view in path integrals.

Very technical book, it does require some advanced physics knowledge. Even when it has very technical explanations, is not hard to read, easy to understand as most Feynman's books.

Creo que es un libro fundamental en la formación de un físico o quimico. Abre puertas a nuevas formas de entender un formalismo diferente
