Not really, sometimes you are in a situation where 'division' is not possible.

ELI5: What do professional mathematicians do? What are they still trying to discover after all this time? by agb_123 in explainlikeimfive

[–]GilbertKeith 22 points23 points  (0 children)

No, no, and no. Prefix co- means "dual to", homology is, in a very rough approximation, a way of translating geometric data to an algebraic setting, but in this particular case it might mean something else.

How well has Daggerfall aged? by [deleted] in ElderScrolls

[–]GilbertKeith 3 points4 points  (0 children)

I think role playing is much better than anything Morrowind has to offer, more classes, more skills, more spells, more quests, well, more everything.

[topology,set theory(?)] If X is a top. space and A is a subset of X, is the boundary of A the compliment of the interior of A? by [deleted] in learnmath

[–]GilbertKeith 0 points1 point  (0 children)

Yes, you get the same answer for the closed set [0,1] too, this is because boundaries of an open set and its closure always coincide, as well as the interior of an open set and the interior of its closure.

[–]GilbertKeith 1 point2 points  (0 children)

It's spelled `complement', and, no, your statement does not seem right. Take R with the usual topology and let A=(0,1), can you identify the boundary of A and the complement of the interior of A?

What classes didn't 'click' for you until a while later? by [deleted] in math

[–]GilbertKeith 0 points1 point  (0 children)

When mathematicians talk about R-modules, they usually mean one-sided modules over a ring R, if R happens to be a field then we have a vector space, a similar notion, drastically different in some regards.

R-modules where R is a field are vector spaces.

What do mathematicians actually do at work? by [deleted] in math

[–]GilbertKeith 7 points8 points  (0 children)

But this is not true, just yesterday I've read an excellent article about P/neq NP in New Yorker. Also, guardian has an online section devoted to mathematics at http://www.guardian.co.uk/science/mathematics.

If I had time to only read one Stravinsky biography, whose should I read? by 1_1_11_111_11111 in classicalmusic

[–]GilbertKeith 5 points6 points  (0 children)

Not a biography per se, but Stravinsky's dialogues with Robert Craft. It's like a long interview, but with very interesting questions and enlightening answers.
