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.

The New Technology of Light

April 25, 2013, 1:14 PM

What's the Latest Development?

130 years after Thomas Edison created the lighting industry with his invention of the incandescent bulb, digital technology is creating novel uses for the unique properties of light. "Innovations on the horizon range from smart lampposts that can sense gas hazards to lights harnessed for office productivity or even to cure jet lag. Digital lighting based on light-emitting diodes—LEDs—offers the opportunity to flit beams delicately across stages like the San Francisco-Oakland Bay Bridge" creating an elegant light sculpture. Energy savings remains a major goal and thanks to recent advances, developers say energy savings will no longer come at the cost of light quality. 

What's the Big Idea?

Major practical applications of new lightening technology will soon be seen in offices and hospitals. In offices, better lighting can improve productivity. New systems optimize the illumination for the task you're doing. "If you sat at your desk to use the computer, maybe the overhead light would dim, increasing the contrast so you could see better. Other lights could go to an energy-saving hue." In hospitals, the psychological impacts of lights are under consideration. Researchers have created, for example, "blue-light-emitting poultice to relieve muscle pain by releasing the nitric oxide in the patient’s system, stimulating blood flow."
