It was a real treat to see scientists who are on the cutting edge of their field take the role of student with another leading edge scientist in a different field. Even the underlying thought, from which the film derives it's name is refreshing. No matter what we know, there is always something yet unknown! If only the rest of us arm-chair scientists could demonstrate such humility with each other, we might advance as a society more rapidly! Good stuff.*

*One caveat was the monkey scientist at the end...were it not for her exuberant boasting that the film would definitely be good because she was last....
