What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Volcanoes from space!

April 7, 2010, 7:05 AM

Actually, no the volcanoes aren't from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit:


A recent image of Chaiten taken by EO-1. Image courtesy of the NASA Earth Observatory.

  1. There is a great image of the busy Kamchatkan Peninsula, where four volcanoes are seen erupting in a single image - Kliuchevskoi, Bezymianny, Shiveluch and Karymsky. The plume from Karymsky is especially prominent as a grey streak above the white snow of the Russian winter (albeit it already April 2 when this image was taken).
  2. The EO keeps presenting us with great shots of the Eyjafjallajökull-Fimmvörduháls eruption in Iceland. This one, taken April 4, shows both vents and the lava flows snaking down drainages out of the snow zone into the lowlands near the Fimmvörduháls Pass. Based on the activity last night, the eruption is still going strong. The Icelandic Met Office posted an image of the collected seismic data leading up to the eruption that shows the ascent of the magma as well.
  3. Finally, as we approach the 2nd anniversary of the Chaiten eruption in Chile, we have a new image (taken April 3) of the dome and surrounding landscape around the volcano. It is remarkable how much the new domes have filled in the caldera. Soon, the old caldera will no longer be a negative relief feature on the map and Chaiten will again be a "mountain" rather than a hole in the ground.
