Sean Carroll visits Google to discuss his book "The Big Picture: On the Origins of Life, Meaning, and the Universe Itself." Already internationally acclaimed for his notions in modern physics, Sean Carroll's book brings extraordinary intellect to our deepest personal questions. Where are we? Who are we? Are our emotions, beliefs, hopes and dreams ultimately meaningless in the void? Does human purpose and meaning fit into a scientific worldview? Carroll's presentation of the scientific revolution from Darwin and Einstein to the origins of life, consciousness, and the universe is unique. He shows how an avalanche of discoveries in the past few hundred years has changed our world and what really matters to us. Originally published in May of 2016.
