"None of us can know what the world is in the way that we used to know it. Einstein says that time is not the same for all of us but different for each one of us. It is very hard to conceive of such separate views, of such relative way of seeing. Today is the first day of a new world that is much harder to live in: less certain, more lonely."
from the movie, Einstein and Eddington (2008).
