I am a postdoc at the University of Osnabrück in Germany. I study (stable) homotopy theory which is a branch of topology. I am particularly interested in commutative ring spectra and computational questions.

It is a corollary of whoever proved that a product of spaces is a categorical product.

comment Why is the cohomology of a $K(G,1)$ group cohomology?
I agree, it is very revisionist. However, today one might learn the subject without dealing with topological spaces. I think it is a subject or part of algebra that might be treated in its own right (admittedly, this approach might leave some at a disadvantage.)

comment Why is Top a model category?
We should be careful to note that there are two Stroms who could have conceivably written such a paper.

comment Sullivan model of the odd sphere
I believe you can since you are constructing the model. You are really picking a graded vector space and then applying $\Lambda$, if I recall correctly...

comment Chern classes fiber bundle projective space
you seem to be asking a lot of questions that look like homework... and are poorly phrased.
