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 Talismans Work

November 4, 2010, 7:00 AM
"It's often assumed that unsophisticated people are most likely to be drawn to talismans, but intellectuals and corporate titans are drawn to them, too, says Dr. [Scott] Sandage, [an American history professor at Carnegie Mellon University]. Personal talismans often are most meaningful when they offer a sense of connection to a time, place or community. Dr. Sandage, 46, keeps a small box on his office desk, which contains an odd assortment of items, including a hose clamp, a chrome lug nut, some brown string, and a 13/64th drill bit. After his dad died last year at age 88, this box was discovered among the few belongings he'd brought with him when he moved into a nursing home."
