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.

Wednesday Whatzits: Katla Update, Cleveland heads back to Orange and Russia's Valley of the Geysers

After a little (ahem) confusion this morning, we're back on track (for now). A few quick hits for a grey Ohio morning:

Iceland: The news from Katla hasn't changed much since I updated the post yesterday evening. Seems like the prevailing idea is meltwater from within the caldera percolated into some of the fractures in the caldera and may have helped produce some of the harmonic tremor that was registered. However, it is unclear from what I can read whether any actual eruption occurred - most likely there could have been some very minor steam exhalations. The seismicity at Katla has settled down some, but everyone will still keep a watchful eye on the Icelandic volcano. UPDATE: Jon Frimann added a link to an article (in Icelandic) that suggest a lot of yesterday's action was hydrothermal in origin - which doesn't contradict the idea that water was the culprit for some of the tremor. However, it all does mean that things are getting hotter inside Katla. Magnus Tumi Gudmundsson from the University of Icelands adds that "These signs usually indicate that magma is coming into the volcano in relatively shallow and the increased likelihood of eruption. But if we look at the examples we have the is common for such activity dies out before the eruption occurs, but we can never know beforehand." The article also had this image of melting on the Mýrdalsjökull ice cap:

Alaska: After lowering the alert status at Cleveland in the Aleutians, AVO has had to turn around and raise the status back to Orange/Watch after spotting continued growth of the dome in the active crater. Cleveland is so remote that it is hard to get an idea of exactly what is going on, especially when clouds obscure the summit from the prying eyes of satellites.

Russia: I ran across this article that talks about Russia's desire to make Kamchatka's Valley of the Geysers into a tourist site. In fact, the Russian government is pumping in over $3 billion to get the location, famed for its over 90+ active geysers and springs, on the travel map. Of course, Valley of the Geysers does have the disadvantage of being on the Kamchatka Peninsula, which makes the place that people like to compare it to - Yellowstone - look like it is easily accessible. However, even if you can't take the trip to Valley of the Geysers, you can check out the virtual tour including 3D models that has been created for the area.
