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.

December 17, 2009, 9:28 AM

Before it gets lost in the mists of time/finals, here is the weekly volcano report brought to us by the USGS and the Smithsonian Global Volcanism Program.

Highlights (not including Mayon, Soufriere Hills or Piton de La Fournaise):

  • Fuego in Guatemala produced ash plumes that reached 4.1-4.7 km / 13,500-15,400 ft along with avalanches of volcaniclastic debris.
  • Also in Guatemala, lava flows erupted from Pacaya, traveling hundreds of meters from the main vent area.
  • Manam in PNG produced an 3 km / 10,000 foot ash plume as part of its renewed activity this year.
  • The lava dome on Nevado del Huila in Colombia continues to glow - and produce significant ash, one with a plume that reached 7 km / 23,000 feet.
