I've certainly read and studied material explaining f), but I haven't read the original paper (besides, isn't that in German?). The proofs aren't that hard, as I remember them, maybe they're harder in original form? To be clear: I specialized in logic, formal verification and programming language theory at uni. This was a while ago, and I'm on new parent amounts of sleep, so pls b nice.
I have tried to read some articles and watch some videos "explaining" Godel but never really understood it. Everyone seems to be explaining the mechanics of what Godel did but explaining the Why is lacking i.e. What was it in mathematics that got him even thinking on these lines in the first place? Can this problem be demonstrated with a simple toy axiomatic formal system? How did he hit upon his approach? Answers to these sort of questions is what seems to me the most important thing to understand before following his arguments.
I recently came to know of The Annotated Godel: A Reader's Guide to his Classic Paper on Logic and Incompleteness by Hal Prince which i think i need to sit with :-)
