This past week we've been covering generic operators in 6.945, which is great because it's a set of questions I'm just getting around to. What are the important data-types/-structures/objects in general relativity, what are the important operators and procedures, and what are their arities and applicabilities? Here are some potential object types (I'm using "object" in a general sense, not with the usual CS implications):

Some basic operators: Some tests: Some more specific operators: And some tools:
Turns out I wasn't using the latest version of scmutils and that's why a bunch of calculus functionality was missing... whoops!
Time is tick ticking away but I feel that things are starting to fall together, doing problem sets for my GR class is super valuable, I wish i'd done more practice exercises before to test myself. But overall I feel pretty mathematically prepared.
Over the weekend I went back and tried to review some topics from topology like Baire dimension theory, embedding, and the fundamental group. I never really covered these topics when I studies topology before, so I wasn't able to gleam any insight.
