Season 3, Episode 26 – Aired 5/20/14
Light is all around us, but we don’t often think about it. Light comes to us as energy, as necessary for vision, as a metaphor for good and seen as counter to darkness. The sun was worshiped in many ancient societies as a deity. Prometheus’ fire stolen from the gods brought humanity fire and light. Even the name of the Enlightenment is steeped in luminosity. Light is even appropriated as a form technology and energy production. Through prisms and telescopes humanity was able to learn spectroscopy and understand the chemical compositions of elements in distant galaxies. In this episode Aneil and Adam go on an ‘enlightening’ journey through the many manifestations of light in practice and metaphor, its politics, promises, and challenges.
