Let's have an algebraic topology thread.

Yesterday I learned about Eilenberg-MacLane spaces. That is for a group G and a natural number n you can construct a topological space K(G,n) such that G is the n-th homotopy group and all other homotopy groups are trivial.

Can I get a similar result if I want more homotopy groups to be non-trivial and to equal other previously specified groups? For example if I have a set of groups (Gi) with i in some finite or countably infinite index set, can I find a space where the i-th homotopy group is Gi for all i? Or is there some obstruction making such a space impossible?

Need help.

Hi guys, I'm helping my friend out with calculus. I wanted to make a graph that shows the tangent line for y=ln[x^2/[(x+2)(x-3)]] when x = 1 but wolfram alpha isn't cooperating. Can anyone help me out? I am fairly sure this should be possible.

So the girl I like is a pop-scientist. What do
I do?

Why are math autists and engicucks always so analpained about CS majors?

Jealous that we are the ones doing real work? While engicucks do grunt work in SolidWorks, and Math autists are starving on the streets, we are getting shit done in the tech world.

I pity you guys sometimes. You know our Algorithms are not only the future, but far harder than any of the shit that you do.

Triple Integrals is weak shit.
