In the following breath-taking documentary, Professor Brian Cox explains how three key concepts are all we need to understand how all this order arose out of the chaos of what was once only an amorphous cloud of dust: gravity, the conservation of angular momentum and orbital resonance. In order to illustrate the importance of these concepts, Cox explores a natural small-scale solar system that still reveals these processes: Saturn and its beautiful rings, including a remarkable appearance by Enceladus.
Oh yeah, while trying to explain the conservation of angular momentum, he also goes hunting for tornadoes... and then has to run away because he may have gotten too close :)
Don't forget to watch the first episode of this series, which focuses on the sun.
For more, check out the incredible promise of Saturn's moon Titan.
Or learn more about how truly remarkable complexity (like you and me) can literally arise out of disorder in Jim Al-Khalili's The Secret Life of Chaos.
