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.

Robotic Hand Offers Gentle Grip for Fragile Objects

While recent advances in software and technology have made remarkable progress in humanoid robotics, one area consistently lagging in comparison to human ability has been the sensitivity of touch. Now, a new robotic hand offers the precision and gentleness needed to grasp objects as fragile as raw eggs.

Developed by researchers at the University of Chicago, the new gripper relies on a soft beanbag ball in place of fingers. Rather than relying on tactile sensing, it uses a rubber ball filled with tiny glass spheres to about 80% of its volume. When the bag is pressed on the target object, the micro-balls mould to its shape and a pump creates vacuum to pull them in place for a secure yet gentle grasp of the object as the force is distributed evenly across the gripping surface.

Larger versions of the hand can grasp multiple objects at the same time.
