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.

Turrialba in Costa Rica erupts and a close view at Poas

January 5, 2010, 5:15 PM

Yet another new eruption for 2010!

Turrialba in Costa Rica erupted today, prompting the evacuation of tens of people from the region near the volcano. The eruption appears to be relatively small, producing ash and some pyroclastic material. The area around the volcano is not very populated and isn't near the profitable coffee-growing region of Costa Rica. This eruption is the first at Turrialba since 1866, over 130 years ago. That eruption was a VEI 3, so Turrialba is definitely a volcano to watch if the activity continues.

Also in Costa Rica, Poas volcano is erupting. Tourists captured early stages of the eruption. A CBS affiliate in Georgia has a story about the video, although the article is pretty vague in many ways, including:

  • "He says this type of volcano doesn't put out liquid lava. It instead puts out a dry lava with steam."
  • "Tom says that this is the first time in the history of Costa Rica that anyone has recorded video of an erupting volcano."

So, a little sketchy. It think the reports got a little confused with the difference between explosive and effusive eruptions. However, the videos (click on the right side menu to see more) are rather impressive (and short), although the tourists seem a little blase about the eruption going on right in front of them. However, why Tom thinks this is the "first time in the history of Costa Rica that anyone has recorded video of an erupting volcano" is beyond me (hello, Arenal). It is interesting video nevertheless.
