"How can we understand the world in which we find ourselves? How does the universe behave? What is the nature of reality? Where did all this come from? Did the universe need a creator? Most of us do not spend most of our time worrying about these questions, but almost all of us worry about them some of the time.
Traditionally these are questions for philosophy, but philosophy is dead. Philosophy has not kept up with modern developments in science..."
