Description

In this episode Brian Cox visits South East Asia's 'Ring of Fire'. Attending the annual Day of the Dead in the Philippine highlands, he explores the thin line between life and death, and raises the question: what is life? Brian explains the laws governing energy and reveals life to be a conduit through which energy passes. Visiting a volcano, he demonstrates how the first spark of life may have arisen through a source of energy created by chemical changes. He explains how the order of life can be possible given the second law of thermodynamics. So life is a chemical process. Far from demanding a mystical explanation, the emergence of life might be a consequence of the laws of physics.
