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.

Steam-driven eruptions continue at Bulusan in the Philippines.

After a few months of intermittent explosions since late 2010, Bulusan in the Philippines looks to be at it again (although not really a "major volcanic eruption" as the Huffington Post claims). The volcano produced a 3 km / 9,800 feet plume (top left) while the Tokyo VAAC is warning of ash as high as FL120 (3.6 km / 12,000 feet) - you can check out another shot of the plume here. Noise from the explosion was heard up to 10 km from the volcano PHIVOLCS director Renato Solidum says the eruption was another phreatic (steam-driven) event, however at this point it is unknown if the ash is still only accident (old) fragments or juvenile magma. This explosion appears to have been unexpected as the last Bulusan update from PHIVOLCS said there had been no seismicity at the volcano. So far, though, it looks like this eruption is on par with what we've been seeing since the fall. PHIVOLCS have kept the Alert Level at Bulusan at Level 1 with a 4-km exclusion zone near the volcano.

UPDATE (2/21/2011): It appears that the series of explosive events on Monday (see above) have prompted the Philippine government to call for ~2,000 people to evacuate the area closest to the volcano. Ash from the eruption fell on over 17 towns that are populated by over 100,000 people, just to give you an idea of the population near Bulusan. The Philippine government has also declared a "no-fly" zone around the volcano due to the threat of new explosions.
