Science is primarily an investigation of our place of the Universe — the place that people occupy in a world which ranges from the tiniest subatomic particles to the furthest reaches of space and time. We do not exist in isolation, and science is a human cultural activity, not a purely dispassionate striving after truth, no matter how hard we might try. It is all about where we came from, and where we are going. And it is the most exciting story ever told.
