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?

After an 18 month shutdown at the Culham Centre for Fusion Energy, experiments are up and running again as the world's premier physicists search for an unlimited and clean energy supply. In the lab's reactors, stars about the size of a minivan are created, burning at 21 million degrees centigrade. "At the heart of a star, fusion occurs when hydrogen atoms fuse together under extreme heat and pressure to create a denser helium atom releasing, in the process, colossal amounts of energy." During the shutdown, more heat-resistant tiles were placed in the reactors. 

What's the Big Idea?

For many people, fusion power remains in the realm of science fiction, and despite large research efforts over the last 50 years, the promise of energy from fusion has always remained a generation away. "Last year, when asked to name the most pressing scientific challenge facing humanity, Professors Stephen Hawking and Brian Cox both gave the same answer: producing electricity from fusion energy. The prize, they said, is enormous: a near-limitless, pollution-free, cheap source of energy that would power human development for many centuries to come."
