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.

Portable Radar Could Help Locate Buried Disaster Victims

What's the Latest Development?

Representatives from NASA and the US Department of Homeland Security demonstrated a new device that can locate people buried under up to 30 feet of crushed material. The device, Finding Individuals for Disaster and Emergency Response (FINDER), works by "[isolating] the tiny signals from a person's moving chest by filtering out other signals, such as those from moving trees and animals." Developers borrowed the technology from that used by NASA's Deep Space Network to locate the Cassini spacecraft as it orbits Saturn: "A light wave is sent...and the time it takes for the signal to get back reveals how far away the spacecraft is."

What's the Big Idea?

When rescuing victims buried by buildings that collapsed due to earthquakes, bombs, or other disasters, time is of the essence. Homeland Security program manager John Price says, "The ultimate goal of FINDER is...to quickly identify the presence of living victims, allowing rescue workers to more precisely deploy their limited resources." It can penetrate through solid concrete up to 20 feet, and in open spaces can find people from up to 100 feet away.
