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.

"Eruption" in Azerbijian

February 4, 2010, 5:14 AM


A 2010 mud flow from Lok-Batan, a mud volcano in Azerbijian.

So, first there was all the Yellowstone talk. Then the unsubstantiated reports of a volcanic eruption in a decidedly unvolcanic part of Pakistan (what part isn't), then submarine volcanism off Japan. Now, we have a nrews report about an eruption in Azerbijian. Luckily, although the headline implies a magmatic event, the text of the article shows that this is, in fact, a mud volcano. The mud volcano is called Lok-batan (or Lokbata) and has erupted quite a few times over the last 150 years, as recently as 2005. Azerbijian has quite a few mud volcanoes, some of which are quite impressive. Remember, "mud" in the ground is just a viscous fluid - water and soil more or less - so it too can behave like lava if it becomes pressurized, especially thanks to heating of the mud. Earthquakes (common along the shores of the Caspian Sea in Azerbijian) could provide a route to the surface for the pressurized mud, leading to the "eruption". The most famous mud volcano in the world is like the Lusi Mud Volcano in East Java, Indonesia - a feature that was likely triggered by man-made action.

Quite the volcano week, eh?
