How does this book help you?

Dozens of illustrations help you understand Quantum Mechanics more effectively.

No-Nonsense Quantum Mechanics is the most *student-friendly* book on Quantum Mechanics ever written.

Here’s why.

First of all, the book is nothing like a formal university lecture. Instead, it’s like a casual conservation with a more experienced student. This also means that nothing is assumed to be “obvious” or “easy to see”.

Fully annotated equations allow you to follow the steps in any calculation immediately. No more re-reading or endless searching for equations.

Each chapter, each section, and each page focusses solely on the goal of helping you understand. Nothing is introduced without a proper explanation why it is worth thinking about and it is always clear where each equation comes from.

The book contains no fluff since unnecessary content quickly leads to confusion. Instead, it ruthlessly focusses on the fundamentals and makes sure you understand them in detail.

Hundreds of sidenotes remind you of the most important facts whenever they are needed.

- In total, the book contains more than 100 illustrations that help you understand the most important concepts visually.
- In each chapter, you’ll find fully annotated equations and calculations are done carefully step-by-step. This makes it much easier to understand what’s going on in.

Key ideas and equations are highlighted such that it’s always immediately clear what’s really important.

- Whenever a concept is mentioned again after its initial introduction, it is accompanied by a short side-note reminding you where you read it before and often repeating important details.
- Summaries at the beginning of each chapter make sure you never get lost.

**About the author**

Hey! My name is Jakob and I’m a theoretical physicist based in Karlsruhe, Germany. My passion is finding the simplest possible explanations for seemingly complex topics and one of my favorite mantras is: “*any scientist who can’t explain to an eight-year-old what he is doing is a charlatan.*”

This is the common theme in all my projects.

**Praise for Jakob Schwichtenberg’s Books**

The problem is that we are not actually taught this stuff and so we just kind of perform the drunkard’s walk on the path to understanding the material. But your text has already been tremendously insightful and I am only on page 52!

### Nicholas Valverde

I am a student in the elite master course in theoretical and mathematical physics at LMU and I recently started to study your book. Needless to say, it is a masterpiece. I fully agree with everything you wrote in it. This is exactly the book a physics student needs.

### Federico Roccati

This is a quite wonderful text in the sense that it is very down to Earth and doesn't assume you are a genius who can fill in the details from the sky [...] I'm glad I spent the money on this book, it contains a lot of important physical insights as to why the mathematics work the way it does. Not every physics author does this, nor for mathematicians either.

### Marcus Quinn Rodriguez Tenes

Really helped me understand what was going on in my undergraduate degree.

### Naim Hussain

First let me tell you that I liked your book a lot . It is the best introduction to physics I have read in a long time .

### Rudy Blyweert

I really love this book, since I at last have found a lucid text that I can read on the train, sitting in a park etc.

### G. Ullman

Undergraduates, today and in the future, are so lucky to have this book. It’s the book I wish I had as an undergraduate, it would have saved a lot of time and misplaced effort. Future undergraduates will not have to experience the frustration of trawling through various dense texts, on topics within this new book, but were written for a much more advanced reader.

### Paul Wakefield

This is the book I’ve been looking for all these years – a clear, concise, well-written summary, from an introductory level, of advanced (for me, at least) physics topics [...]

### Dave Pendleton

This is a fantastic book that deserves the widest possible audience. [...] So I am finally gaining a deep understanding on the character of physical law; this approach has profound explanatory power. If you have ever wondered why nature is the way it is and not some other, this book can give you new tools to approaching an answer. Overall, a very fine, deep physics book.

### Jandro Kirkish

Well done! Easy to follow as a self-study text, and one that I would recommend to any undergraduate or older graduate.

### James Gort

We want to make sure that our books are as helpful as possible. We encourage our readers to discuss the content of the book with each other and give us feedback on everything they like or dislike.

For this reason, we release only 100 initial copies of each book. This makes sure that we can participate in the discussions and no feedback gets lost in our inbox.

After the first 100 copies are sold we update the book based on the feedback we received. (This process takes some time and there is no fixed date.) Afterward, we will release another limited number of copies at a higher price. If you missed the first 100 initial copies, make sure to sign up below to get notified when we release further copies.

If you buy the book now you will receive a free digital copy of all future editions.

**FAQ**

**What if I want to buy the eBook and the paperback version? Do I get a discount? **

You can buy both versions on Amazon. And, yes, you will get a discount.

**Are the derivations in this book mathematically rigorous?**

No. If you’re interested in mathematical rigour, there are much better Quantum Mechanics books available. Try, for example, “Quantum Theory for Mathematicians” by Brian Hall, “Quantum Theory, Groups and Representations” by Peter Woit or “An Introduction to the Mathematical Structure of Quantum Mechanics” by Franco Strocchi.

**Do you offer a revolutionary new interpretation of Quantum Mechanics?**

No. This book contains neither crackpot interpretations nor content that might earn me a Nobel prize. No-Nonsense Quantum Mechanics is a book about well-established topics, and the main focus is to present these topics in the most student-friendly way. However, there are several sections on topics that other beginner textbooks don’t mention, even though they are well-established among experts. And I believe students can get much deeper insights by finding out about them at an earlier stage.

**I’m a non-native speaker. Will it be hard for me to understand your book?**

No. The book is written in simple language, and each technical term is carefully explained.
