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.

Sagan on the 4th Dimension

In honor of the return of "Cosmos," which we covered here on Big Think, check out classic footage from the original show. A lot has changed since "Cosmos" first aired. We know more now than we did back then, and science today is strangely debated between, well, scientists and creationists. Watch our interview with Bill Nye explaining why creationism is not appropriate for children.

Neil deGrasse Tyson, everybody's favorite astrophysicist and the new host of "Cosmos," explained that part of his inspiration for doing the show is that he does not want tomorrow's leaders to not know or care about science. 

We look forward to watching his show. "Cosmos" airs this Sunday on FOX and The National Geographic Channel.
