Why many great books just feel out of league

Mathematically inspired books are often hard to read, it seems like they only spray paint equations for the unthinking person, or they are for AI to read…
By knowing the fundamentals, the equations are rather obvious in the concept space where manipulations are of which concept is truly intended. Although, equations may be trying to specifically point out the rather exact concept, but can be meaningless in reality for practical implementations, but only useful to show the greatness of the authors.
For example, a person inventing a concept is great not because of the concept might be great, but because it has been preached by many, even there could be better concepts which did not see the light of the day, and rather than dwelling to the person (who are remembered forever after they are gone, those who contributed to their well being are not remembered forever), for e.g. Newton’s law, merely is the law interpreted by a sentient being, evolved in carbon life, more precisely a human being at certain point in history, called Newton. The point is not to remove the credibility, but to rather have a different feeling when invoking the universal laws without borrowing the cultural connotations that might rather bias the theories and knowledge there in, although for people it can be enriching as they live their life, but far reaching knowledge requires knowing all of it at once as it exists, we as sentience in this universe often fail to take ourselves into these equations, ignoring ourselves, then later only to complain why some things didn’t work, but including ourselves as conscious can also lead to feelings of lack of free will for the self, but ultimately a computer may not fully understand itself say on individual transistor level it works on, but through generalization it can allow itself to know and understand parts of itself scanning the whole,…

Again, a book meant for some audience is not for all audience, and any books are fine as they can be thought as the written response of the being from the universe, and output is the book, written as it is, in the state that it was…
