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's the Latest Development?

Across the developing world, innovators are finding ways to make technology cheaper and therefore accessible to millions previously excluded by high costs. Affordability is often the greatest hurdle to overcome but here are five areas where it has been achieved: inexpensive tablets, laptops, and mobile phones; rotating solar panels and nanotech toilets.

What's the Big Idea?

Improving sanitation is key to the progress of developing countries, which is why Bill Gates, for instance, pledged to reinvent the toilet. Last year, India’s Tata Chemicals released an affordable water filter that uses nanotechnology, requires no electricity and meets U.S. sanitation standards. The filter is made of rice husk ash and fine nano-silver particles to prohibit bacteria growth.
