37. Category theory

Just found this: http://math.ucr.edu/home/baez/treilles/

Some mathematicians suggest that Category theory (http://en.wikipedia.org/wiki/Category_theory) is more fundamental than Set theory and should be taken as new basis of math. Matti has discussed also Category theory but I believe he prefers his recent idea of Quantum Mathematics to the Category theoretical approach. How ever both Matti and John Baez agree that Set theory is not enough to make sense of this world on scientific level, and the idea of Hilbert space math seems to be in the air and coming through many channels.

I also know and accept my mathematical limitations, my skills don't go much further than developing again in Platonic anamnesis figurate numbers (http://en.wikipedia.org/wiki/Figurate_number) long time again when when obsessing about tetrahedra and bipyramid made of two tetrahedra.
