Solar Dynamics Observatory Shows Sun‘s Rainbow of Wavelengths

NASA – 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.

Yellow light of 5800 Angstroms, for example, generally emanates from material of about 10,000 degrees F (5700 degrees C), which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, which is typically colorized in green in SDO images, comes from atoms that are about 11 million degrees F (6,300,000 degrees C) and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths – as is done not only by SDO, but also by NASA’s Interface Region Imaging Spectrograph, NASA’s Solar Terrestrial Relations Observatory and the European Space Agency/NASA Solar and Heliospheric Observatory — scientists can track how particles and heat move through the sun’s atmosphere.

I wrote the Anarchist Cookbook in 1969. Now I see its premise as flawed

By William Powell – Forty-four years ago this month, in December 1969, I quit my job as a manager of a bookstore in New York City’s Greenwich Village and began to write the Anarchist Cookbook. My motivation at the time was simple; I was being actively pursued by the US military, who seemed single-mindedly determined to send me to fight, and possibly die, in Vietnam.

Over the years, I have come to understand that the basic premise behind the Cookbook is profoundly flawed. The anger that motivated the writing of the Cookbook blinded me to the illogical notion that violence can be used to prevent violence.

I had fallen for the same irrational pattern of thought that led to US military involvement in both Vietnam and Iraq. The irony is not lost on me. more> http://tinyurl.com/nr8jpug

Farewell QE, you have been a magnificent success

By Ambrose Evans-Pritchard – The diverging fortunes of the QE bloc and the EMU bloc prove beyond doubt that monetary stimulus packs a powerful punch.

America has this year weathered the most drastic austerity cuts since demobilisation at the end of the Korean War in the 1950s. Net fiscal tightening has been 2.5pc of GDP, yet the economy has muddled through. The Fed‘s $85bn monthly bond purchases – soon to be $75bn – have blunted the shock. more> http://tinyurl.com/kgzrut8

R&D – Instead of creating large amounts of power in one place—from large dams or even small turbines in water treatment plants—there’s value now in making tiny amounts of electricity anywhere there is a water source, from streams to water faucets.

Carnegie Mellon Univ.’s Diana Marculescu is leading a multidisciplinary team of industry and academic researchers to develop novel monitoring tools for placement and control of hydrokinetic generators throughout river systems nationwide. more> http://tinyurl.com/oc53cry

Tone-Deaf at the Listening Post

By Daniel Drezner – The NSA can point to their triple-branched oversight as much as they like, but as Ryan Lizza and others have documented, that doesn’t mean that the oversight is terribly effective.

The NSA’s biggest strategic communications problem, however, is that they’ve been so walled off from the American body politic that they have no idea when they’re saying things that sound tone-deaf. Like expats returning from a long overseas tour, NSA staffers don’t quite comprehend how much perceptions of the agency have changed. more> http://tinyurl.com/ovz7quc
