Next Sunday night sbs are showing a documentary on the history of light. I hope it will help me to understand the light rule.

08:30 pm DOCUMENTARY SERIES – LIGHT FANTASTIC – Let There Be Light

This four-part science series explores the phenomenon that surrounds and affects nearly every aspect of our lives but one which we take for granted, light. Greek and Arab scholars, and later Europeans such as Descartes and Newton, all tried to understand light to gain a better understanding of God. Tonight’s first episode examines how much of modern science’s origins came from the desire to penetrate the divine nature of light. Presented by Cambridge scholar Simon Schaffer.
