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.

What's the Latest Development?

Hydrophones -- underwater microphones that work similarly to Skype -- are helping researchers at different institutions learn more about the world's oceans by capturing, for example, "everything from thrumming boat motors to the wild sounds of transient killer whales" at one location off the coast of British Columbia. Even better, live audio is available round-the-clock at multiple Web sites, including the one for the PALAOA autonomous observatory located in Antarctica. According to the site, two hydrophones transmit data over 15,000 kilometers to the Alfred-Wegener-Institut in Germany. The result "is not optimized for easy listening, but for scientific research...You might need to pump up the volume -- but beware of sudden extremely loud events."

What's the Big Idea?

The hydrophones represent one of several sound-based technologies scientists are using to fill in many of the blanks that still exist concerning the oceans and the life within them. Some of these tools have uncovered "fish shoals stretching 25 miles long, invisible whale migrations, and entire ecosystems revealed in the echoes of the bodies of squid, herring, and billions of other organisms."
