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.

Nevado del Huila

May 3, 2008, 11:02 AM


I've been following these rumblings for the last few months, but it looks like Colombia's Nevado del Huila is ramping into a new cycle of eruptions. Huila lives in the shadow of its more famous brethren Nevado del Ruiz and Galeras, both of which have had recent and tragic eruptions. Huila is not believed to have been active since the 1500s, but little research has been done on Huila (or any Colombian volcano beyond the aforementioned duo), so it might have had some fits and spasms in the last 500 years. 

Reports from INGEOMINAS, the Colombian Geological Survey, say that Huila has been erupting ash intermittently for the last few months, although confirmation of the VEI of the eruption is difficult thanks to the volcano being clouded over. However, Huila is erupting enough to prompt the evacuation of over 13,000 people near the volcano. I'll update when I find any more information on these eruptions.
