Abstractions and Generalizations
I.
The generalizations of modern theoretical physics are astounding, but then again, a model that explains the nature of reality itself would be far from trivial (not to mention it isn't even the "truth", there are important things to explore).
II.
RAM was a mystery to me. A little demystification followed after playing this wonderful game (though I did not complete it). But the jump from NAND gates to RAM, with memory management was something that still puzzled me, until this video pulled back the veil. Building things up from nand gates to games was quite the journey for computer scientists.
III.
Theories for human behaviour at large has received a lot of attention in the last decades. I speak with someone who has very little exposure to this field (not naming any fields, since it feels like this can be anywhere between philosophy and psychology). Nonetheless, I was quite interested in Ken Wilber's theory, explored in this youtube video. All I'll say is this seems like a good philosophy of ... knowledge ? I don't know.
