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.

Mind-Controlled Robots Restore Autonomy to Quadraplegics

What's the Latest Development?

By controlling a robotic arm and hand with her mind, quadriplegic Jan Scheuermann successfully high-fived someone, moved objects of different shapes and sizes and even fed herself a bar of chocolate. "Less than a year after she told the research team, 'I’m going to feed myself chocolate before this is over,' Ms. Scheuermann savored its taste and announced as they applauded her feat, 'One small nibble for a woman, one giant bite for BCI.'" In the study, published in the online version of The Lancet, researchers explain that Ms. Scheuermann had not intentionally moved a hand in nine years. 

What's the Big Idea?

Researchers were amazed with the rapid progress they made, working to map brain signals in a series of weeks. It was a task they had expected to take months. "Our findings indicate that by a variety of measures, she was able to improve her performance consistently over many days," Dr. Schwartz explained. "The training methods and algorithms that we used in monkey models of this technology also worked for Jan, suggesting that it’s possible for people with long-term paralysis to recover natural, intuitive command signals to orient a prosthetic hand and arm to allow meaningful interaction with the environment."
