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.

Green pre-fab is getting a lot of attention right now in New York City. Hop downtown to the Financial District, and you’ll notice, amidst the suits and skyscrapers, a peculiar exhibit.

Ozone Overload: Kudzu Vine To Blame

over 4 years ago

Here’s the tricky thing about ozone: we want lots of it up high in the upper atmosphere, where it blocks radiation and protects us, but we want as little of it as possible down here on the surface of the earth, and in our eyes, ears, noses and throats, where it acts as a harmful pollutant. And ...

The Tortoise And The Oil Spill

Around the turn of the 20th century, if you were in the upper class in America, you’d have probably, at some point, sat down to a nice dinner of Diamond Terrapin turtle. The species, native to Alabama, was a sought-after delicacy then – now, after decades of industrial growth and commercial fishing ...

Even Conservationists Ignore Oceans

over 4 years ago

With exactly 40 Earth Days in its wake, the US has come a long way on conservation awareness. But when we think about Earth and all that ails her, we’re still remarkably bad at paying attention to those big blue bits on the map – those bits which, we often seem to forget, make up almost three ...

GWOTWOW: Global War On The War On Weeds

over 4 years ago

The first job my mother ever held involved plucking hundreds of dandelions by their tenacious little roots from her family’s tiny lawn. Her father had set her to the task, and incentivized her by paying her a penny a pop. Like most Americans in the 50s, he disliked weeds. A lot. But the times they ...
