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.

A few snippets from the world of volcanoes:

  • The current eruptive cycle at Galeras continues to go strong. Officials with INGEOMINAS, the Colombian Geology Survey, believe the volcano will erupt again in the next few "days to weeks". The volcano last erupted a few weeks ago (in spanish) and caused quite a bit of panic in the city of Pasto at the foot of the volcano. An Orange Alert has been issued (in spanish) for the volcano.
  • Another volcano have is on the verge of a larger eruption is Nyiragongo in the DR of the Congo. Reports of "by day, the air in the city is thick with volcanic dust. By night ...the red glow of burning lava trickling out of the summit of the nearest volcano [Nyiragongo]" Additionally, one of the scientists at the Goma Volcano Observatory reports that "significantly increased temperatures had been recorded around Mount Nyiragongo recently and a larger than usual cloud of volcanic dust was being thrown into the skies". Interestingly, he also mentions that Nymuragira, not Nyiragongo, is the volcano they expect to erupt soon.
  • Not much new to report on the Redoubt front. The dome collapse has yet to occur and seismicity at the volcano has tailed off compared to last week. Still, always a good idea to take a peak at the webcams.
  • The erratic behavior of Llaima (in spanish) has government officials in Chile on edge. There is still an active lava flow emanating from the volcano, plenty of volcanic gas and ash emissions - mostly in the form of orange/black plumes that reach a few hundred meters and constant low-level seismicity.
