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: Yellowstone plume, man-made lava and monitoring Hawai`i

December 9, 2009, 5:29 AM

Some news for today:


Yellowstone National Park, USA.

  • Another fine example of media headline versus actual research, an article in the Jackson Hole Daily about a new study by Dr. Robert Smith and others on the Yellowstone plume was titled "Park's giant magma plume eating up mountains". Yikes! Well, the actual study published recently in the Journal of Volcanology and Geothermal Research is more about the geophysical parameters of the Yellowstone plume - a plume that might reach as far as 500 km below the caldera itself. As for the mountain eating part, I think they were trying to get at the idea that as the North American plate move over the plume, the topography over the plume will change (thanks to the bulging of the plate), thus "erasing" mountains - however, this is a minor part of the study. The most interesting thing (at least to me) is speculation of what might happen when the plume hits the colder, thicker crust of the North American Craton.
  • In what can only be described as the closest thing to a man-made lava flow, a glass factory in Ireland had one of its furnaces crack, producing a giant molten glass flow. The glass (at ~1600C) flowed out of the furnace and filled an area 2-3 feet deep in glass. Luckily, no one was killed, but I'm sure there are folks who study glass rheology dying to get a look at the results of this spill. Might be the only time firefighters in Ireland will have to deal with lava flow-like events!
  • Volcano monitoring in Hawai`i looks to get a big upgrade with an announcement of ~$420,000 for updating the system and research. Sounds like a lot of the money will go to study the vog problem on the Big Island of Hawai`i. Overall, the USGS received $7 million from the Department of the Interior as part of the ARRA.
