LIST OF SUBJECTS, IN LOGICAL ORDER ARE ON THE SIDE. (Not everything has to be done in this order, but this approximately indicates the logical coherence of the various subjects. Some notes are at a higher level than others).

I mean I “get” what you’re saying, but it’s such a vague notion in this context. You can learn precisely as much as you are willing to. I’m not even a physics major (CprE undergrad, SE by trade), yet I have a working understanding of Schrödinger equation mathematics. This was not born out of elective or required study, I taught myself QM post-graduation with a textbook & MIT-OCW. I worked through the textbook up to TISE. I went back and relearned Frobenius method to understand how the 3D hydrogen atom results in these wild ass wave equations. My point is I’m in an adjacent field (that I’m already continually extending my knowledge in) and I can still find time to climb the modern phys ladder if/when I feel like it.
And then on top of that, like I said this website is a shopping list for “would-be crewmen”, so I think it’s reasonable to assume the man is listing everything he has studied, so you can “study everything”. Now maybe what you mean to say is you can’t go deep in everything. But you can become conversationally proficient across subjects, so that you can be able to ask the right questions.
In general, “you can’t study everything” seems vague or off-topic.
