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.

“Tyrannosaurus rex and its relatives were North America's dominant predators in the late Cretaceous period, about 99 million to 65 million years ago, but a new analysis of a toothy fossil skull suggests that the early history of this group includes smaller meat-eating ancestors that date as far back as 170 million years ago. The skull belongs to the only known specimen of Proceratosaurus, which now represents the oldest known relative of T. rex and its cousins, extending the evolutionary history of tyrannosaurs back to the middle of the Jurassic period…Analysis shows a close evolutionary relationship among Proceratosaurus, which was found in England, and other recently described tyrannosauroids found in China, including Guanlong, a 160-million-year-old feathered specimen described in 2006 by Xu Xing of the Chinese Academy of Sciences in Beijing; Dilong, a 130-million-year-old specimen described in 2004 by Xu; and Raptorex, a 125-million-year-old specimen described this year by Paul Sereno of the University of Chicago.”
