The Secret Life of Chaos

I watched this one-off documentary yesterday (it was rebroadcast earlier this year, and it's taken me a while to get round to watching it again). Jim Al-Khalili explains how we get complexity from simplicity, and as far as abiogenesis is concerned the implication is clear. It makes "intelligent design" a superfluous theory.

The hour-long documentary is no longer available on iPlayer, but there's a dedicated webpage with several clips, and with luck it will be rebroadcast yet again. (It was apparently available on YouTube for a while, but all instances appear to have been removed.)


Here's the blurb from the BBC website:
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. 

It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here? In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science - how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder?

It's a mindbending, counterintuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.

And the best thing is that one doesn't need to be a scientist to understand it. The natural world is full of awe-inspiring examples of the way nature transforms simplicity into complexity. From trees to clouds to humans - after watching this film you'll never be able to look at the world in the same way again.
Inspiring stuff.
