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.

Taking stock in the Eyjafjallajökull eruption and its aftermath

April 23, 2010, 6:31 AM


A night shot of the Eyjafjallajökull eruption showing the glowing plume from the strombolian explosions and the Aurora Borealis overhead.

A quick update on the current activity at Eyjafjallajökull eruption: the eruption continues at the summit craters, but there seems to be less ash being erupted, at least yesterday. The latest update from the Icelandic Met Office suggest that things are settling down - but floods are still periodically being produced by melting of the glacier:

Volcanic tremor has been similar the last 24 hours. GPS stations around Eyjafjallajökull showed deflation associated with the eruption.

The plume could be seen on IMO's radar till 04:00. This morning it rose up to 16.000 feet, ca 4.8 km, and ash is blowing towards west.

Water in Markarfljot river increased slightly yesterday, probably due to continuous flow from the eruption area (Gigjökull).

You can keep up with changes in the ash cloud over on the UK Met Office Volcano Blog.

As the hub-bub begins to die down from the Eyjafjallajökull eruption, we can talk about some of the interesting ramifications of such a prominent volcanic eruption (at least in terms of the amount of news coverage):

UPDATE: One quick update, but here is a great post on the NASA Earth Observatory, showing not only the visual record of the ash plume, but also compositional data. Great stuff!

UPDATE 2:: OK, one last update - here is an article from NSF talking about the state of glaciovolcanic studies. Lots of nice images modern and ancient evidence of lava-ice interaction.

Unless something changes dramatically, I likely won't have any new posts until Monday - but feel free to post any interesting related information here!
