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.

FDA Approves New Device, Allowing the Blind to See

What's the Latest Development?

The Food and Drug Administration has approved the first-ever device that works like an artificial retina to help blind people see shapes, shadings and even distinct colors. "The artificial retina is a sheet of electrodes implanted in the eye. The patient is also given glasses with an attached camera and a portable video processor. This system, called Argus II, allows visual signals to bypass the damaged portion of the retina and be transmitted to the brain." While the device does not allow the blind to see in a conventional sense, contrast between light and dark allows them to identify the outlines and boundaries of objects. 

What's the Big Idea?

In everyday life, the device will allow the blind to recognize street crosswalks, the presence of cars and large numbers or letters indicating an address. The new vision technology was developed over 20 years by Dr. Mark S. Humayun, an ophthalmologist and biomedical engineer at the University of Southern California. "Dr. Humayun said he envisioned applying the technology to other conditions than blindness, implanting electrodes in other parts of the body to address bladder control problems, perhaps, or spinal paralysis. 'We don’t think of the human body as an electrical grid, but it runs off electrical impulses,' he said."
