Does anyone else detect a distinct lack of this particular maths on this board?

What kind of geometry? Any highschool-level, Euclidean geometry is boring.

Therefore, the only geometry we should discuss is differential geometry, algebraic geometry, etc.

Btw does anyone know what "noncommutative geometry" is? It looks interesting but I'm too stupid to comprehend any introduction found online.

I'm particularly interested in n-skeletons, 4-cells, etc.

I like to draw lines between points.

Come on guys,

at least post some non-Euclidean stuff. Or fractals.

I dislike fractals, but ok.

I much prefer to study higher dimensional solids.

That's for (algebraic) topology. Used mostly for computing a space's simplicial homology so not that much to do with geometry.

It really isn't. You define topological spaces without any geometric consideration.

all geometry past Euclidean geometry is pseudoscience

Nothing wrong with Hatcher unless you're autistic or french. I like Munkres a lot. One of my teachers mentioned Bredon's Topology and Geometry book but I didn't find the time to study it.

Do you understand spectral sequences, I'd like to get an intuition for them.
