so wow i now have an intuition for (co)homology, finally! that took forever.
i still can't crunch out calcs with it, but i get what the chain condition is about, how it relates to "the boundary of the boundary is zero" and i'm now familiar with a few different versions of chain/cochain complexes, how short sequences become long ones, and why "exactness" matters. oh and how this relates in some sense to de rahm's theorem!
thus resolves what is probably my longest period between hearing a word and being able to even describe what it means in vague handwavy terms.

Laci Maniscalco, a third-grade teacher in Lafayette, La., who said that sometimes her students cried during the past year when working on problems under the new curriculum, said she had seen genuine progress in their understanding — and in her own, as well.
crying, that's how you know it's working right

― The Wu-Tang Declan (James Redd and the Blecchs), Sunday, 31 August 2014 21:50 (nine years ago) link
ack. the general notion of a sheaf i understand only through general abstract nonsense. a tangent bundle involves differential geometry or generalized smooth spaces or something, which gets dangerously close to actual numbers and spaces. i'm of no help there.

this is 100% a stupid question but still.
I used to be really good at maths in school, didn't carry it on to university, but recently I've got the urge to take it up again. I play a lot of numerical puzzles and things but I really want to do problems and spend time trying to work things out again. Yeah, I know that's embarrassing. Anyway, are there such things as maths books for adults that you can buy that have problems and examples etc or would I just be better off picking up secondary school books?
― gyac, Tuesday, 9 September 2014 19:56 (nine years ago) link
Yes! I recommend Strogatz's books:
http://www.amazon.com/gp/product/0544105850/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1535523722&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=0691150389&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=17CZ8R5ZTVM1NJ77SRYC
A terrific introduction to mathematics. It starts with arithmetic and ends with calculus and abstract algebra. His writing is terrific, regardless of subject.
http://www.amazon.com/Calculus-Friendship-Teacher-Student-Corresponding/dp/0691150389/ref=sr_1_1?s=books&ie=UTF8&qid=1410292988&sr=1-1&keywords=calculus+of+friendship
Is also very good. The problems within illustrate the usefulness of calculus.
Textbooks are trickier. Are you familiar with algebra or trigonometry?
― Allen (etaeoe), Tuesday, 9 September 2014 20:05 (nine years ago) link
Yes, both. Trigonometry was actually one of my favourite parts of the course. I'm really more after textbooks rather than books on the topic, but thank you for the recommendations.
― gyac, Tuesday, 9 September 2014 20:17 (nine years ago) link

Whiplash of nostalgia on seeing the book front on Amazon, though mine must've been an earlier edition (as it was 20+ years ago).
Just this weekend got back into redoing my Masters from that time, which was in algorithmics so a few levels below sterling's. But so satisfying to work out an equation for "What are the points equidistant to these two points and this line", and see an set of clattering clauses snap into a simpler form.
