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.

SI/USGS Weekly Volcano Activity Report for 7/1-7/2009

July 8, 2009, 10:53 AM

All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!

Highlights (not include Manda Hararo, Kilauea and Mayon) include

  • San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002.
  • A pilot spotted a ~10,000 foot / 3 km ash plume emanating from Anak Krakatau in Indonesia.
  • Another ash plume, this time at Ubinas, Peru, was spotted by pilots rising to ~6.7-9.1 km / 20-30,000 feet.
  • Explosions were heard from Suwanose-jima in Japan, but no associated ash plumes were spotted.
  • It sounds like a lava dome has been spotted at Sarychev Peak in the Kuril Islands of Russia. An "intense thermal anomaly" was noted at the summit in satellite images and gas/steam plumes have been seen each day. However, no new ash plumes have been noticed since June 16.
