I believe mathematics is the very thing that anytime activates each cell of my body, though it is not my majority. I still believe physics can accelerate the activation. But geometry, I think, connects every branch of them and generates the great beauties that I've seen and not ever seen.
Now I'm pretty intrigued in differential geometry and geometric algebra. And I'm desperately finding new insights of them in many different areas such as dynamic system, pde, Markov chain and also in physics like fluid dynamics, thermodynamics.
