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.

On The Horizon: Light Sources Made Of Glowing Plastic

December 6, 2012, 12:30 PM

What's the Latest Development?

Physicist David Carroll and his team at Wake Forest University have designed a plastic material that gives off a comfortable white glow when electricity is run through it, thanks to carbon nanotubes embedded within. The material can exist as a simple flat panel or it can be molded into shapes, including those of standard light bulbs. Also, they use about the same amount of electricity as LED bulbs: in other words, very little. A paper published in the January 2013 Organic Electronics describes the science involved.

What's the Big Idea?

The technology behind the material, field-induced polymer electroluminescence, has been in development for more than a decade. With the addition of the nanotubes, the plastic gave off five times more light. The quality of the light mattered as well, according to Carroll: "People often complain that fluorescent lights bother their eyes and the hum from the fluorescent tubes irritates anyone sitting at a desk underneath them. The new lights we have created can cure both of those problems and more." The team is working with a company to bring these light sources to market as soon as next year.
