Once a physicist (I don't remember his name anymore) said something interesting, at least in my opinion, and it sounded like this: back to the basics and there are new ways and opportunities.
So we need to remember something, but it is not about definitions or concepts - they will be needed later. It is more generally a manifestation of the existence of reality, which actually exists as a whole of interactions. And here a question mark should be put. ;)

Should I take it literally or figuratively? ;)

That's it. I also left all my books from elementary school to college, and I was always surprised at the behavior of my colleagues who snatched or sold their books after finishing a given subject. I have never been a humanist by passion, but I love technical knowledge, which is why I mostly use books of this type. Well, I am attracted to it ...
Our studies are like they are, a lot of people want to cram into their heads, and not every brain can keep up with it and in the end they start to ignore learning and start downloading. Later, a man remembers that there was something but that he did not understand what it was about, he did not remember it exactly and now he has gaps. Books can be a salvation for this. And what I regret is that not enough things are learned through examples - in application (because it is easier to remember this way, learning through associations).
I wrote too much off topic, but everyone knows how it is.
