Hahah, well, that is a beautiful way to think about it. Thanks to you two!

comment Does $f'(0)$ exist?
Yes, I kinda thought about that, but it somehow bugs me that I know that it is actually wavy. Maybe I'm just overthinking this. It is just that this case is somewhat different from the more obvious cases that I can think of, in which if we zoom in the line will become only very slightly curved. Maybe I just need more time to internalize all this.

I just saw this one a couple of days ago in the bookstore! Seems like a wonderful book - I'm definitely buying it.

I hadn't heard of Gelfand's Algebra, I'm definitely going to look it up. Thank you!

comment Making up for wasted high school years - where should I begin?
Thank you! It is a small university and there aren't that many courses - I believe there are around 20 courses in Maths altogether, and they are all the usual suspects - calculus, analysis, abstract algebra etc. at different levels. Chances are that whatever I begin to study now, I will go through it again at university, so there's no use in trying to synchronize the things I plan to study. Basically, I'm going there for the diploma, the university experience and the other subjects.

comment Necessity and sufficiency
Yes, I understand that. What I was really asking was when p<=>q, which condition do we call necessary and which sufficient, since each of them is both?
