I simply want to offer a word of caution. At this point you actually know something about QM and you are ready to learn the Dirac principles and finally destroy every concept about the reality you had before starting this path. I will also speak about the origins and the importance of quantum physics. Why do you want to study quantum physics? Decoherence and the quantum to classical transition by Schlosshauer is a wonderful book that helps explain why the world seems classical when it's actually quantum. We counted a handful of fairly simple (though important) quantum physics formulas and 34 images. More information on the basics is provided in the first lectures of this quantum physics course. If you are new to quantum physics, this is a great read and you will learn a lot about quantum physics with little effort. It is well tested to extreme levels of precision, and describes all known natural phenomena (excluding gravity). After deciding to learn quantum physics, you will learn about making predictions about the precise location of electrons (as an example) and its movement after that. Quantum Field Theory (QFT), and by extension the standard model of particle physics, is the most accurate theory of nature that we currently have. Which parts of physics you already know? In this quantum physics introduction for beginners we will explain quantum physics, also called quantum mechanics, in simple terms. He makes an excellent case for the Many Worlds interpretation along the way. Black holes, quantum entanglement, and worlds with 11 dimensions—get to know the amazing physics that governs our universe and the math behind it. Quantum physics is possibly the most fascinating part of physics there is. It does get quite technical though, and a lot of the value is toward the beginning. It is the amazing physics that becomes relevant for small particles, where the so-called classical physics is no longer valid. What is your knowledge in math? Even without a strong math background you should be able to read through and understand the book within a weekend. Now start with old quantum mechanics books, not very similar to modern physics, but absolutely necessary if you want to understand WHY did we go the way we went.
