I've finished volume one and now I'm dying to find out what happens next. Talk about a cliffhanger ending!

__________________________________

I must confess that I didn't enjoy the second volume quite as much as the first, but that mainly shows how high the bar was; this is still the best introduction to quantum mechanics I have ever seen, and if you have some mathematical background (linear algebra, calculus) I can't recommend it too highly. It requires some effort to read, but it's definitely wo ...more

ΔE Δt ≥ ℏ/2: "Quantum Mechanics: The Theoretical Minimum" by Leonard Susskind, Art Friedman

I was on a train the other week and I was sitting opposite Einstein who asked me if I would mind changing seats because he liked to see where he was going for a half a journey and then he liked to see where he had been for the other half of the journey and I told him I didn't mind changing seats and I asked him if he minded me asking him if he wa ...more

This is a really nice introductory book on Quantum Mechanics - Quantum Mechanics done for real, with some decent detail and good mathematical treatment of some of its most important aspects.

As a list of prerequisites for fully enjoying this book, I would recommend the following:

- read volume 1 (on Classical Mechanics) which is simply fantastic on its own

- basic knowledge of linear algebra, calculus and complex vector (Hilbert) spaces

The author is great at explaining potentially tricky and compl ...more

We could, of course, use any notation we want; do not laugh at notations; invent them, they are powerful. In fact, mathematics is, to a large extent, invention of better notations.

—Richard Feynman

I’m a bit sad to be finally putting this book down. Now, I can no longer tell friends and coworkers that I’m reading a book about the mathematics of quantum mechanics. Oh well.

I’ve already written a fairly detailed review of the first volume (which can be found here); and since this volume is very s ...more

Susskind's Theoretical Minimum series might not be everybody's cup of tea, but I'm really beginning to love this style (way more than the video lectures, I should add!).

It's not your usual popular science with so much hand waving and analogies it almost feels like patronising, but it's not the usual cold and formal textbook style either.

Susskind manages to explain all the core ideas of the theory in a beautiful and coherent way. Some details must, of course, be omitted, but there's no BS and swe ...more

Quantum Mechanics the Theoretical Minimum by Leonard Susskind and Art Friedman

review by Galen Weitkamp

Perhaps it’s unfair to compare these two works given the differences in the intent of their authors. George Musser is fascinated by what some identify as the nonlocal nature of the measurement process in quantum theory. It seems to this reader that his intent is not only to inform but to convince the reader of its “reality” and the consequences that ...more

I am putting this book on hold for now. I started reading it during a long voyage and it was very interesting and invigorating, like a good workout for the brain. But as soon as I got back to work, I lost the stamina necessary to keep up with the book.

It is hard. The math is real and you have to learn a whole new vocabulary to follow the explanations.

But even if I read only a half of this, I got what I wanted originally. My big question to quantum mechanics was something like "Don't they see ho ...more

As someone with a broader mathematical background who learned some QM before, I was mostly interested in the pedagogical angle the book would take. Most physics books introduce QM from a historical point of view, reviewing the problems lead ...more

*The Theoretical Minimum*, which is a prerequisite to reading this book.

I say here that I've "read" this book, but so far I've only skimmed to get the lay of the land. Because this is not a bullshit popularized treatment of quantum mechanics, it takes actual work and concentration to make your way through it and really understand the mathematics. So this is going to be my background reading for some time to come. ...more

The focus is on finite dimensional systems (i.e., quantum information) initially. This is a similar approach, if I recall correctly, that Isham takes in his

The book starts from a discussion of electron spins, and develops quantum mechanics to explain how spin changes on measurements or if placed in a magnetic field. The Schroedinger equation is derived and explained, and then applied to harmonic oscillators in general.

I think it approches teching QM entirely the wrong way.

- They start from math and show that it can be used to describe QM. This seems backwards to me. We should learn about quantum phenomena, the data, and then stumble on some math than can help us describe that data.

Also, I think their interpretation of QM doesn't make any sense.

- Waves of probability, spin just 'is', entanglement and spooky action at a distnace, observables are treated differently, ... I mean come on.

*The Theoretical Minimum*, which dealt with classical physics, this book explains the basics of quantum theory in a simple (but not oversimplified) way beginning with spin states and working through the Schrödinger equation, combinations of states, entanglement, and the uncertainty principle. The first half of the book introduces the mathematics of complex vector spaces in a very understandable way (I had never studied linear algebra at all, even with real vectors, and I had no troub ...more

“The units that we use reflect our own size. The origin of the meter seems to be that it was used to measure rope or cloth: it’s about the distance from a person’s nose to his or her outstretched fingers. A second is about as long as a heartbeat. And a kilogram is a nice weight to carry around. We use these units because they are convenient, but fundamental physics doesn’t care that much about us.
