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.

A breakthrough has been made in wireless brain-to-computer connection speech synthesizer technology which could allow victims of paralysis the ability to speak again. “A system that turns brain waves into FM radio signals and decodes them as sound is the first totally wireless brain-computer interface. For now, 26-year-old Erik Ramsey, left almost entirely paralyzed by a horrific car accident 10 years ago, can only express vowel sounds with the system. That’s less than can be accomplished with wired brain-computer interfaces. But it’s still a promising step. ‘All the groups working on BCIs are working toward wireless solutions. They are very superior,’ said Frank Guenther a Boston University cognitive scientist who helped developed Ramsey’s system. In the last decade, brain-computer interfaces, or BCIs, have made the jump from speculation to preliminary medical reality. Since Wired reported on quadriplegic BCI pioneer Matthew Nagle four years, the interfaces have been used to steer wheelchairs, send text messages and even to Tweet. They’re so advanced that some researchers now worry about BCI ethics — what happens when healthy people get them? And they’re concerned about the threat posed by hackers. But as amazing as these early BCIs are, they’re far from street-ready.”
