comment Is there a "simplification" functor in algebraic topology?
@QiaochuYuan: Ah, ok, I'd just assumed that $B(G/[G,G])$ was a simplification of BG, but I see what you're saying (the perfect space Y is just the Eilenberg-MacLane space corresponding to the nontrivial cohomology). Probably $B(A_5)$ is already a problem.

Yes, in the homotopy category.

comment Why do universities have to spend money on journals?
Unfortunately, biomedical research drives everything. If we were to have a totally free system for all other subjects, schools would still have to subscribe to Elsevier's Big Deal to get biomedical journals and Elsevier would still charge exactly the same as they would with all the other journals included. That's how they run their business: you can drop of keep whatever subscriptions you want as long as you pay 6% more than you did last year.

comment Is it poor grammar to replace normal phrases with mathematical symbols in sentences in a mathematical paper?
If I read a sentence starting "For matrix A..." instead of "For the matrix A" I would definitely assume the speaker was not a native American English speaker. Sesame Street doesn't say "This episode was brought to you by letter A and number 5."
