I have a very superficial, skin-thin understanding of the science. It [My acting] is just about finding the humanity in all of that. Brilliant people have private moments of self-doubt and things which we could all relate to, but they also have these extraordinary moments of discovery or pioneering (开创性的) brilliance that pushes the envelope in how we view the world. I try not to pull faces – if I do, it has something to do with the character.
