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.

Eruption Update for 11/1/2010: Grímsvötn and Merapi

I'm still at GSA 2010 - I'll have another post with some news/facts from the meeting - but my lack of a computer yesterday and the fact that my hotel is chargest $13/day for internet has left my posting a little slow even with a couple important events ... so here are some brief updates:

Grímsvötn, Iceland

I received a couple emails from Eruptions readers about a glacial flood or jokulhlaup that has started at Grímsvötn. Now, I know that folks have been watching Grímsvötn for potential eruption and rapid production of meltwater to start a jokulhlaup is a sign you might expect. However, so far scientists from the University of Iceland are saying that an eruption has not started as seismicity is still low but rather that the edifice might be heating up and heading towards an eruption. The flow is about twice as high as what might be expected from normal glacial meltwater according to Gunnar Sigurdsson of the Icelandic Met Office.

Remember, you don't necessarily need an eruption to form a glacial flood: if you melt the glacial ice on top of a volcano and build up a body of meltwater, then release it by catastrophic failure of a ice or tephra dam, you can produce a non-eruption-related jokulhlaup. You can read some more details on the flooding and potential of a new eruption on Jon Frimann's Iceland Volcanism Blog and he quotes Pall Einarsson as saying that any eruption at Grímsvötn is expected to be on the scale of the 2004 events.

Merapi, Indonesia

I've been trying to keep up with the news from Merapi - and you can check out all the news I've missed over in the post from October 30 where Eruptions readers have been finding and posting all sorts of information. Merapi is still eruptiing and this is leading to even more evacuations of the area around the volcano - up to 69,000 people have now fled the volcano. So many people have evacuated that there is a shortage of shelters for the refugees. The ashfall has become so significant that many activities at Yogjakarta have ceased due to the ash, including any air traffic in and out of the city's airport. There is no indication that Merapi will stop erupting in the near future according officials from the Centre for Volcanology and Geological Hazard Mitigation and rain over the weekend might increase the chance of more explosive eruptions from rainwater infiltrating the crater area. You can see video of the latest from the Merapi area here.
