Quantum physics related branches

Before you start to study quantum physics or any part of it, you need to know the branches that are related to quantum physics:

Suitable sources for different levels of expertise

Levels of expertise

"I know nothing or a little about it" level

In this phase, you need to understand:

• ... that the goal of quantum physics is to describe the nature as accurately as possible.
• ... that quantum physics was originally motivated by hard-to-explain results of several experiments coming from the domain of small distances. This is, why quantum physics is mainly focused on microworld.
• ... that the predecessor of quantum physics, classical physics, failed to explain the results of the experiments. That is, quantum physics is an inevitable successor of classical physics.
• ... that quantum physics is not a speculation. Quantum physics not only explains a vast amount of phenomena but has also passed an immense amount of experimental tests.

• In the introductory sources, Quantum Mechanics, Quantum Field Theory, and Particle Physics are usually described together with no clear distinction among them.
• You will need practically no math. If any equation is presented to you, in most cases it is just a demonstration that physicists have an equation and that they can use it to calculate things. You can remember that the equation exists, but you need neither to remember the exact form of the equation nor to understand that equation. In the more advanced sources, you will have an opportunity to meet the same equation again (even several times) and to understand it in its entirety.
• The aspect of "no math" implies that nothing will be derived, i.e., everything you will come across will be a collection of statements - sometimes with an explanation, sometimes with a reference to an observed phenomenon or a done experiment.
• If you do not understand something, do not be ashamed to read/watch/listen it once more time. You will be neither the first nor the last person who has done that to understand the subject. Time to time even several attempts will not help. In that case, skip over it. Maybe a more detailed description that you will get in the advanced sources is what you need to have your "I see" moment.

Sources (ordered by level increasingly)

① DoS - Domain of Science, Map of Quantum Physics download poster for free, buy the paper poster, and the related YouTube video, 22 minutes. In learning a subject it is very useful to know what you may come across while doing that. Do not expect any explanations here. The knowledge of the appropriate quantum-related terms also gives you an opportunity for a proactive study because now you know what you do not know.
② Spark, The Mind Bending Story of Quantum Physics and Exploring the World of Quantum Physics with Jim Al-Khalili 2 YouTube videos: Part 1 (59 minutes) and Part 2 (59 minutes). The videos are a very light introduction to history and several concepts of quantum physics. When watching, do not forget that most of the demonstrations in the macroscopic world are only analogies to the behavior on the microscopic level.
③ M. Chown, Quantum Theory Cannot Hurt You (Amazon link) book, almost a pocket edition, 224 pages, with glossary and index; ISBN: 9780571315024 The book covers modern physics, that is quantum physics and general relativity. It is probably the best introduction book to modern physics I have ever read. The book contains very vivid examples, sometimes pushed to their extremes to emphasize their weirdness or unexpectedness.
④ DoS - Domain of Science, If You Don't Understand Quantum Physics, Try This! YouTube video, 13 minutes. The video describes whether physicists understand quantum physics, what applications of quantum physics are, and what quantum physics describes. In the case of quantum mechanics, it describes how quantum mechanics describes particles, namely by a wavefunction and the basic consequences this description has. Besides that, the video concisely explains the double-slit experiment, superposition, entanglement, quantum tunnelling, uncertainty principle, and energy quantization in an atom. The video closes with a visual summary.
⑤ J. Baker, 50 Quantum Physics Ideas You Really Need to Know (Amazon link) book, 208 pages; with glossary and index; ISBN: 9781780879116 The book is a very good compilation of the basic quantum physical topics. It is very well organized. It contains 50 topics in a concise form, each topic is covered in 4 to 6 pages.
⑥ K. W. Ford, 101 Quantum Questions - What You Need to Know About the World You Can't See (Amazon link) book, 304 pages, no glossary, with index, ISBN: 9780674050990 The book digs deeper than the previous two books. Time to time the book contains a simple equation. The question-answer form makes the book incredibly good for the real understanding the subject through giving you a different perspective.

Undergraduate student

Here I expect:

• you are an undergraduate student with quantum mechanics, quantum field theory or particle physics in your study program, or
• you are an entusiastic layman.

Sources on history of Quantum Physics

① M. Veltman, Facts and Mysteries in Elementary Particle Physics (Amazon link) book, 352 pages, name index, subject index, ISBN: 9789813237490 This is an incredibly well-written book. It is organized by concepts but always mentions its history including their protagoinsts. Life and work of the protagonists is consicely described always on an individual page. Although being a popular book, it consists many insights. It is definitely worth to read it twice, now to get the general idea about the subject and later to appreciate the details you do not see elsewhere.

Sources on Quantum Mechanics

To start Quantum Mechanics on this level and understand everything, you need to know basics of Elementary algebra, Linear Algebra (at least be able to work with vectors and matrices), and Calculus (at least be able to work with derivatives and integration).

① David J. Griffiths, Introduction to Quantum Mechanics, 3rd edition (Amazon link) book, 508 pages, with subject index and an appendix summarizing Linear Algebra you will need, ISBN: 9781107189638 This is an exceptionally well-written introductory book on quantum mechanics, with many on point questions and insights. Besides that it consists a lot of illustrations and is typographically well processed. It is a joy to study from a book like this. If you do not know what motivated the creation of quantum mechanics, go back to the "I know nothing or a little about it" level and leave this book until later. This is because this books will not tell you that, and you might get the impression that quantum mechanics is an subject on its own with no relation to our physical world.
② L. Susskind, Quantum Mechanics: The Theoretical Minimum (Amazon link) book, 364 pages, almost pocket edition, with subject index, ISBN: 9780141977812 If you know several quantum-mechanical concepts and want to start to use mathematics in Quantum Mechanics, then this book is the best, especially if your level of mathematics is not too advanced. The book will introduce you many important aspects of Quantum Mechanics and shows you in a very comphehensible way how to describe them mathematically. Since most of the Linear Algebra you will be using is described on the way, the knowledge you need to know to finish this book is basic Calculus (derivatives and integration).

Sources on Quantum Field Theory

To start Quantum Field Fheory on this level and understand everyhting, you need to know basics of Elementary algebra, Linear Algebra, Calculus, Quantum Mechanics and Theoretical Physics (at least Hamiltonian and Lagrangian formalism).

① J. Schwichtenberg, No-Nonsense Quantum Field Theory (Amazon link) book, 642 pages, with index, Further reading recommendations, and appendix "Cumberstone Calculations", ISBN: 9783948763015 This book is very student-friendly. The student-friendly approach is demonstrated: a) by chapter "The Bird's Eye of View" which gives you a simplified overview of the subject, b) by chapter "What Everybody Ought To Know About Quantum Field Theory" which gives you a condended course on the main topics, c) by summarizing the starting point or the mail goal in the beginning of the most sections, d) by not only explaining the main concepts in a comprehensible way but also explaining terms which are rarely explained elsewhere, and e) by presenting calculations without skipping the intermediate steps (which is normal in more advanced texts).
② T. Lancaster, Quantum Field Theory for the Gifted Amateur (Amazon link) book, 512 pages, index, Appendices: Further reading, Useful complex analysis, ISBN: 9780199699339 If you are good at math and know something about theoretical physics, this book is perfect for you. The book presents you in 50 chapters a very wide range of topics on quantum field theory. Even though it is roughly 10 pages per chapter, the book digs relatively deep compared to other books. If after reading this book you decide to dig even deeper and to continue in studying quantum field theory, the book can be used as a good source of topics you would like to know more about.
③ A. Das, Lectures on Quantum Field Theory, 2nd edition (Amazon link) book, 776 pages, with index, ISBN: 978-9811222160 This book is organized in a way similar to most of the textbooks on quantum field theory are organized. Nevertheless, this book stands out because of clear derivations, the straight-forward language and the clear arrangement.

Sources on Particle Physics

To start Particle Physics on this level and understand everyhting, you need to know basics of Quantum Field Theory and Classical Electrodynamics.

① David J. Griffiths, Introduction to Elementary Particles, 2nd edition (Amazon link) book, 470 pages, with index, with appendices: Dirac Delta Function, Decay Rates and Cross Sections, Pauli and Dirac Matrices, Feynman Rules (Tree Level), ISBN: 978-3527406012 This is a classic textbook among the particles physics textbooks. On the first almost 60 pages, the book describes historical context and the main experimental results. Then the book gradually touches all the main topics of elementary particle physics in a very pedagogical manner. Since the last edition came out in 2008, the book covers only the knowledge of Higgs particle known prior to its experimental discovery in 2012.
② M. Thomson, Modern Particle Physics (Amazon link) book, 570 pages, with index, Further reading, and several appendices, ISBN: 9781107034266 This incredibly well-written book is probably the best up-to-date introductory book on elementary Particle Physics. It is written in a clear and straight-forward language, contains a lot of illustrations, and thus it is easy to follow the the main idea of each chapter. The readabillity is also improved by the summary at the end of each chapter. Time to time the book refers an experiment and presents its result.
③ A. Bettini, Introduction to Elementary Particle Physics, 2nd edition (Amazon link) book, 492 pages, with index, ISBN: 9781107050402 A very well-written book. If you tend to go to the experimental side of the subject rather than to the theoretical one, this book is for you. Don't get me wrong, the book covers all the theoretical aspects of elementary Particle Physics, but more often than other books mentions experiments relating to the studied subject and more often presents the concrete numbers both calculated theoretically and measured in an experiment.
