Here, the late, great, Maynard Smith talks about what it means to say something is living. Like many virtuosos, he makes something difficult seem simple, with utterly clear explanations - the lecture is a small masterpiece.
He considers that what some biologists (such as Stuart Kauffman) define as life i.e. self reproducing things that metabolize, does not differentiate between life and something like a flame and that we must always add heredity (of infinite possible variety) to account for what we consider to be truly alive.
This leads to life as seen from an information perspective i.e how we transmit information between generations, and he outlines 9 milestones in the evolution of life from this vantage point, from replicating molecules to electronic information communication.

Do You Want To Live Forever?

Spacefest 2009 will be held in San Diego Feb 19-22 next year in San Diego. This trailer is a great taster. It is also a way to plug the place where I found it, my favorite new weblog: Bad Astronomy, which is bad ass, indeed.
