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.

Friday Flotsam: Plume images and a restless (?) North Korean volcano

June 18, 2010, 4:08 AM

This week went fast, didn't it?


The Baekdu caldera along the North Korean/Chinese border.

  • The NASA Earth Observatory have been giving us a steady diet of volcanic plumes over the last week, including PNG's Ulawun, Russia's Sarychev Peak (a very faint plume), both an ASTER and Terra image of the summit region at Kliuchevskoi and finally a mix of plume and clouds over PNG's Manam volcano.
  • I wanted to also mention a brief article I ran into on the Changbaishan/Baekdu caldera along the Chinese and North Korean border. Although short on specifics, this article mentions a number of interesting (and potentially odd/wrong) things: (1) Baekdu is showing signs of "becoming active" - this is the first I've heard of that, but the article does mention increased seismicity, inflation of 10 cm since 2002 and an increase in surface temperature; (2) the North Korean government is creating "comprehensive countermeasures" in case of an eruption - I have no idea what this means, it almost suggests they want to come up with ways to stop the eruption, which is ridiculous; (3) that the recent North Korean underground nuclear test might have had an effect on the magmatic system at Baekdu - and this strikes me as 100% pure speculation. The volcano has a caldera lake at the top, known to the Chinese as the "Lake of Heaven" and a Korean-speaking population living around the edifice. If Baekdu were to erupt, it would be a very large problem for North Korea's already teetering economy and government - the eruptions tends to be explosive with the last coming in 1903. However, Baekdu/Changbaishan did likely produce a VEI 7 eruption ~1000 A.D., meaning any activity at the volcano should be closely monitored (which could be difficult with its location on the Chinese-North Korean border).
