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?

Juan-David Hincapié-Ramos, a postdoc researcher in the human-computer interaction lab at the University of Manitoba, has created technology that will eventually enable its user to stay focused on his or her smartphone without having to look out for things like curbs, benches, or other people. The aptly-named CrashAlert system "uses a depth-sensing camera to spot obstacles and pops up a warning on a smartphone screen...allowing you to safely navigate public spaces without taking your eyes from your handset." The prototype, which consists of a tablet computer with an attached Microsoft Kinect unit, is described in a paper that will be presented at the Computer Human Interaction Conference next month.

What's the Big Idea?

These days, especially in large cities, it's not uncommon to see people staring deeply into their smartphone screens, so when Hincapié-Ramos says putting down the phone to navigate isn't realistic, he may have a point: "[I]n order to incorporate [cell phones] into our everyday new habits, they have to help with the things they take away from us, like peripheral vision." Stanford professor Clifford Nass, who also studies human-computer interaction, isn't impressed: "Why do we want to encourage people to be disconnected from the world?"
