The cost/benefit equation for reducing U.S. carbon emissions should be compared to global emissions before we hobble our economy any more than we have with regulations.

Now I’m wondering what “rejected energy” is, and how we can accept it.

The Weight of Mountains

This is a short film about the processes by which mountains are created and eventually destroyed. It is based upon the work of British geographer L. Dudley Stamp, and was shot in Iceland.

Physical geography and geology is an enormous and fascinating subject, and this film only touches upon the surface of the discipline.

Gorgeous.

Stanford Professor Andrei Linde celebrates physics breakthrough

Assistant Professor Chao-Lin Kuo surprises Professor Andrei Linde with evidence that supports cosmic inflation theory. The discovery, made by Kuo and his colleagues at the BICEP2 experiment, represents the first images of gravitational waves, or ripples in space-time. These waves have been described as the “first tremors of the Big Bang.”

"B-modes of gravitational waves have been detected in the cosmic microwave background radiation.” (via io9)

Solar Dynamics Observatory Shows Sun’s Rainbow of Wavelengths
This still image was taken from a new NASA movie of the sun based on data from NASA’s Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors. (via NASA)
