Friend of the Blog (and Dark Energy Song performer) Lloyd Knox, Professor of Physics at the University of California Davis, has teamed up with undergraduate students David Gribble and Justin Smith and graduate student Damien Martin to launch a new endeavor - The Spherical Cow Company - which

... produces short documentary videos to demonstrate the explanatory power of simple physical models and to help us understand and aesthetically appreciate the natural world.

Their first video discusses the Cosmic Microwave Background - a central feature of modern cosmology, and one of our most important tools for exploring the universe. In this episode, Lloyd shamelessly follows the well-worn path of other entertainers before him in pushing their children - in this case his son Teddy - into the business. Lloyd and Teddy explore what the CMB means on their kitchen table with a pen and paper, cutting to more high-tech descriptions of the material where appropriate. It's entertaining stuff, while retaining the nice feel of sitting down to an informal chat with an expert. I think you'll enjoy it and, if so, I hope you'll return to take a look at their future efforts.
