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.

The Loose Ends of String Theory

January 18, 2010, 1:20 AM

String theory has been one of the most famous ideas to emerge from physics in the past 50 years, yet a vocal minority of physicists have criticized its failure to provide testable experimental predictions. In an interview this week, Columbia University's Peter Woit untangles a fundamental model of nature his book calls "Not Even Wrong" and voices skepticism that it will turn out to be the long-sought-after "theory of everything."

Woit goes on to explain the nature of the elusive Higgs particle and the role the new Large Hadron Collider (LHC) will play in proving its existence or nonexistence. Having tied the viewer's mind into some intricate theoretical knots, he then discusses his experience as a physics blogger, and the unintentional comedy that results when the average Internet commenter pits his wits against Nobel-winning scientists.
