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.

Yellowstone: the return?

May 26, 2008, 10:52 AM


Everyone loves a "supervolcano"*. According to a recent report, Los Angeles will be erupting from underneath Yellowstone Caldera (Wyoming). OK, not really, but apparently there has been 7 cm of uplift underneath the footprint of the Yellowstone Caldera since 2004, which is a pretty good amount of uplift. Whether this uplift is caused by new magma intruding, volcanic gases collecting or hydrothermally spawned (however, in the article, we are to believe these unnamed "researchers" that it is magma). I'll keep an eye out for more on this, but it sounds like this is just another "more uplift!" sort of report.

* you know, I am still pretty ambivalent towards this buzzword "supervolcano". Really, the term has only been around, or at least in popular use, for the last 10 year or so, and it just smacks of media jargon. There already is a word for volcanoes that erupt this much material in large eruptions. They're called "calderas". Sure, it doesn't have the same visceral reaction as "supervolcano," but it also doesn't sound like something from a Jerry Bruckheimer film.
