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.

Air Pollution App Finds Healthier Commuting Routes

What's the Latest Development?

By creating a network of tiny air quality monitors, researchers at the University of San Diego's medical school hope to give commuters, especially those travelling by bicycle or on foot, more information about choosing healthy routes to work. Called CitiSense, the device is designed to monitor the air for ozone, nitrogen dioxide and carbon monoxide, the most common pollutants from car and truck traffic. "We want to get more data and better data, which we can provide to the public," the monitors' lead developer, William Griswold, said in a statement. "We are making the invisible visible."

What's the Big Idea?

The EPA already requires cities to maintain air quality monitoring stations but those stations are often too sparse to detect street-by-street differences and recent experiments with the CitiSense device show that pollution levels can vary significantly over juts a few yards. "In the future, if the monitors become more widespread, they could help researchers perform more-precise studies about how air pollution exposure affects people's health... Previous studies have linked air pollution to increased risk for lung and heart diseases."
