I am working on the template of this blog today in order to chase down some problems that have developed with my template and widgets.

Science Saturday
Cosmos "One Voice in the Cosmic Fugue"

This is part of a series of video posts for Saturday Mornings called "Science Saturdays" and will generally be posted at 9am Eastern Time every week.

For the first series of posts, I must (of course) post Carl Sagan's Cosmos. It has become the yardstick by which all video science series are measured. I will be posting one episode per week.

This the second episode of Cosmos, "One Voice in the Cosmic Fugue", to see the 1st episode, "The Shores of the Cosmic Ocean",

In this episode, Sagan tells the story of the Heike Crab to describe how artificial selection works and uses the Watchmaker analogy used by creationists (of which I am one) to describe Intelligent Design. He reviews where different steps in the evolution of life occur fit into the Cosmic Calender and an animated evolution from microbes to man is presented.

We are taken on a journey, by way of the Kew Gardens of London, into the cell nucleus. Then, we are introduced to the Urey-Miller Experiment and the common biochemistry of all life in earth.

Sagan then speculates about life in the clouds of Jupiter. This is my favorite part of the episode.

At the end, a ten year update is delivered.
