What is the Hopf Fibration?

3. I'd like to look at de Serre's spectral sequence. It's about manifolds that have been decomposed into fibrations and
I hope it will nurture us with geometric intuition as we go.

A #fibration decomposes a space X into fibers F which intersect the base space B once:

F -> X -> B

Serre spectral sequence: the singular (co)homology of the total space X of a (Serre) fibration in terms of the (co)homology of the base space B and the fiber F.
