Stephen Hawking's Grand Design S01E02 - The Meaning of Life

Hawking tackles the question: Is there a meaning to life? Is there a purpose to our existence? He explores what the laws of physics reveal about who and what we humans really are. Do we have free will or are we just complex biological machines working to the laws of nature? From Descartes to the latest advances in quantum physics, Hawking explores this fascinating territory with his famous fearless zeal as he questions the very nature of reality itself. You'll never look at yourself the same way again.
