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.

How Is the Weather in Space?

March 16, 2011, 5:47 AM
New data from the THEMIS probe launched in 2007 is giving us insight into weather patterns in space: "Back in 2008, data from THEMIS helped overturn a long-standing hypothesis about when the magnetopshere is the most 'leaky.' Scientists thought that when the sun's magnetic field was aligned with that of the earth, there were fewer 'leaks' allowing solar particles to penetrate the 'shield.' But it turns out that the opposite is true: 20 times more solar particles penetrated the Earth's magnetophere during periods of alignment, as opposed to when the two magnetic fields were directly opposite."
