A multicolored blade of light seems poised to strike over a snowy forest in Ivalo, Finland, on January 22. Late last week a NASA satellite witnessed a solar flare and CME from a different active region on the sun. That solar event triggered a round of auroras over the weekend, including the display captured above.

Tenured Professor Departs Stanford, Sets Sights on Teaching 500,000 Students at Online Start-Up

Mr. Thrun told the crowd his move was motivated in part by teaching practices that evolved too slowly to be effective. During the era when universities were born, “the lecture was the most effective way to convey information. We had the industrialization, we had the invention of celluloid, of digitial media, and, miraculously, professors today teach exactly the same way they taught a thousand years ago,” he said.

He concluded by telling the crowd that he couldn’t continue teaching in a traditional setting. “Having done this, I can’t teach at Stanford again,” he said.
