I managed to organize my sharable intellectuality into (more or less) 4 categories: Writings, Readings, Problems, and an extra section for Outliers (which is why there's a "more or less". That's my way of avoiding making more labels, though certainly I can add more structure here; but who said more structure is a good thing?).
By "Writings" I mean some excerpts on math and science (or related/unrelated topics), mostly written by myself in a general-audience-friendly manner (i.e. for myself as a way of personal reflection; but it's not particularly personal, just more of trying to address questions I like). In Readings, I will post some responses or impressions of stuff I read or watch; I might occasionally post the reading itself in case I found it interesting/fun enough (though  I am unsure about the whole copyrights thingy, so I might abstain from doing that). By "Problems" I mean the homework exercise type of problems, math and science ones; surely, these are not going to be the usual high school level exercise, but rather more profoundly beautiful ones (at least in my eyes; in the end, beauty is in the eyes of the beholder, and it is my personal space). The Outliers section will include all sorts of extra materials (videos, essays, books,..) that are not necessarily related to STEM disciplines. I have also added an out-of-context CV section where I had put some of my actual CV.
