Given the closure of the p-adic numbers is isomorphic to the complex numbers, is there notation and use for its one point compactification?
I passed? I passed! *made of tiredness*
Yet tempted to go back to studying because I almost got how that one piece worked?!
It's a good class when I want to just keep going after the end.
Handwriting - notebook from M's class. (Cover and random pages of mathy stuff)
This notebook was my second brain for a while; I know nearly every page of it down to typos and contradictions. And now I have to switch again, back to the computer world.
If a tool is a part of your body you can put down, what is a part of your mind?
+eleventy this solution;
I'd been slacking on academic reading and consuming mostly compsci articles because they tended to be available in (readable) blog form.
It's amazing to me how much faster I read in a good interface. Now https://arxiv.org/abs/1610.09366 is a quick skim rather than a slog. Fantastic!
I possibly can't apply for scholarships because I still have exams from the summer which don't happen until after the deadline. =/
grad school angsts Show more
The feeling that Masters isn't 'real' grad school and I'm still a lowly student compared to the PhDs doesn't usually bother me much. But once in a while... *sigh* It's different here than in the states.
Otoh I firmly realized today that I have a good chance of taking a compsci PhD if I don't get to do one in math here. Every path is a good path. Just gotta do the work.
I'm getting confused again on local/global principles. :/
Is local meaning locally compact, or p-adic p-part, or mod p, or ... what's a p-part anyway? This is not fantastic.
So then I notice that the background reference to the main reference to the stuff the prof riffed off of with minimal explanation ... notes its expected level as 3rd yr grad students by usa standards.
Uh... I'm finishing my first year. No wonder I'm a smidge swamped.
I feel so much better about a long list of "let"s if I write them as a cast of characters at the beginning of a play.
If you run out of books, the intro chapter to a phd thesis by a prior student of whoever is being confusing is a good bet.
Never try to understand the first or last chapter of a book.
Instead, find another book where that material occurs in the middle.
Two pages of 'Let …' later
yup I'm lost.

Degree of legibility needs to be an up-front requirement.
Not just for crypto (lack of legibility sans key), or ai (legibility of decision processes), or terms of service (how many pages of fine print?), but everyday protocol and software stacks (how does a webpage? what servers are talked to? why?).
System illegibility getting out of hand is not acceptable going forward. Neither are accidental legibilities (data leak). Specify up front who should understand what.
I'm not lost, I know exactly where I am. I'm just temporarily uncertain of where everything else is.
