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.

Huila coughing up ash

If the current activity around the world wasn't enough, I just found a report that Nevado del Huila in Colombia had an ash-producing explosive eruption today. The Colombian government is working on an evacuation of the area, but the details of the extent of the ash is unclear. The report on Huila from INGEOMINAS (spanish) posted yesterday afternoon noted over 400 earthquakes under the volcano over the last week and sulfur dioxide emissions at ~4400 tonnes/day at the volcano. They concluded that these data points suggest that magma is moving and that magma extrusion (eruption) is likely - so, they were right about that! Huila has been have intermittent eruptions for the last few years after centuries of quiet - and ash plumes were reported as recently as last month.

This is the second eruption in Colombia in the past week, with Galeras having a non-explosive eruption last week that prompted evacuations as well.
