Michio Kaku

Michio Kaku is a theoretical physicist. He is also a figure skater. I think that probably for him, both are forms of art. To hear him talk about physics or figure skating (or both at the same time), his incredible creativity and artistry is quite apparent:

He uses mathematics to express his ideas and theories about the world around him, which it seems to me, is a kind of creative outlet for expression, albeit one that I will probably never be able to fully understand. While I may not be able to gleam any meaning from the pages of equations that Kaku writes, they hold meaning for him, and for others. Nonetheless, Kaku is very good at explaining the meaning of physics theories in a way that allows people without specialized physics knowledge to grasp some meaning from them, which opens his artistry up more to everyday people.
