Braid groups and B sub 2 being isomorphic to the set of integers. Beautiful. Now about those Betti numbers…

Enter symmetry and groups :D

Starting fresh

Sheaves, finite fields, modular arithmetic, the Frobenius symmetry, and back to those eternal functions. Absolutely beautiful

Thinking about the dimensions of circles and spheres in a whole new way. Love groups and Lie Groups and the various sub fields. Fantastic, beautiful stuff.

Fundamental groups, oh yeah

Rosetta Stone baby
