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.

Two Indonesia volcanoes making noise: Soputan and Papandayan

It seems that the volcanoes of Indonesia are restless this August - and this weekend was no exception. Two volcanoes made the news as unrest reached levels high enough for Indonesia officials to call for evacuations. The first was at Papandayan, a composite volcano on Java that last erupted in 2002. Gas emissions from the main "Golden Craters" at the volcano along with the threat of a phreatic (steam-driven) eruption have prompted a 2-km exclusion zone around the main crater - however, they have lowered the alert level from 3 to 2 since the initial warning during the weekend. Papandayan is a popular tourist destination, so enforcing the exclusion might be difficult. The volcano has only had 4 known historic eruptions, with the eruption in 1772 ranking as a VEI 3 that produced almost 3,000 fatalities.

The volcano getting attention is Soputan on Sulawesi. We've been watching the volcano since early July of this year as it sprang back to life. It appears that new lava is being erupted from the summit crater - and small explosions reaching 1 km in height have been occurring as well. The lava flow has made significant progress down the volcano (see top left), producing some stunning images at night. PVMBG has established a 6-km exclusion zone around Soputan due to this renewed activity.
