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 If Your Physical Body Was Your Password?

What's the Latest Development?

At this week's 11th All Things Digital conference -- also known as D11 -- Motorola Mobility executive and former DARPA head Regina Dugan presented two unconventional solutions to the problem of remembering passwords. The first was an electronic tattoo, containing an antenna and sensors, that authenticates devices when held up to them. The second was a pill containing an electronic chip that, once ingested, would send out an 18-bit signal from within the user's body, such that only a touch would be needed in order to get into a locked phone or laptop.

What's the Big Idea?

Wearable technology is growing by leaps and bounds, and the tech for both of the concepts presented by Dugan already exists to some extent. The tattoo was built using material developed in John A. Rogers' flexible electronics lab at the University of Illinois, and ingestible sensors are already FDA-approved for medical use. While Dugan likened taking the pill to gaining a super power -- "My hands are like wires, my arms are like alligator clips" -- All Things Digital's Walt Mossberg nervously mentioned Motorola's parent company when handling the pill: "Does Google now know everything I do and everywhere I go?"
