I want to understand some sections of physics a little, in order to understand the operation of the processor?

Question

Electronics

I want to understand how modern technology works, and I realized that you need to start with atoms, and even further, but I just can’t find enough deep literature. I want to understand all the necessary physics (as I understand it, all electrodynamics, etc.) at a fairly deep level, with a Matan minimum.
Tell me where you can learn all this, school textbooks mainly teach you how to solve problems, they don’t explain everything very deeply, and even without a soul at all, Feiman is too sickly heavy, a lot of superfluous for me. Charles Petzold misses some details from physics, I'm already tired of looking.
For example, the other day I studied the model of an atom, what the electron shell looks like and why atoms are bonded into molecules. Everything went easily, it’s quite easy to understand the quantum model of orbitals, why and how chemical bonds work and look, but when I got to electrodynamics, I wondered why electrons flow from - to + and that’s how many hours I can’t find the answer. How much I don’t read on this topic, either everything goes into “how to calculate this and the heavy matan begins, where I disappear” or such moments are skipped and only technical details are explained, for example, how the electrical circuit is arranged, etc. In short, tell me where you can understand how it works? Maybe some books?

Answer 1

In order to understand the operation of the processor, it is not necessary to dive into physics. The processor operates at the level of logical elements AND, OR, NOT and their combinations, Boolean algebra. Learn better circuitry to understand the operation of flip-flops, adders, what a synchronization signal is for, etc.

Answer 2

Rudolf Svoren - "Electronics step by step A practical encyclopedia of a young radio amateur"

Answer 3

Zee "Physics of semiconductor devices", if you dive into physics, fascinating reading, but a lot of swearing, a special course begins with it at the corresponding departments, that is, there should already be a mathematical and physical "base".
