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.

The angels, cherubs and putti depicted in Christmas nativity scenes are “anatomically flawed” according to a scientist who claims they would never be able to fly with their flimsy wings. “Prof Roger Wotton, from University College London, found that flight would be impossible for angels portrayed with arms and bird-like feathered wings. ‘Even a cursory examination of the evidence in representational arts shows that angels and cherubs cannot take off and cannot use powered flight,’ said Prof Wotton. ‘And even if they used gliding flight, they would need to be exposed to very high wind velocities at take off - such high winds that they would be blown away and have no need for wings. Interestingly, the artist Giotto showed one angel with a rigid 'mono-wing’ which could be an adaptation for gliding flight. But if they do just glide, how are the wings folded, unfolded and held rigid?’ Angels, cherubs and putti (babies with wings) adorn some the world’s most famous religious paintings and architecture, hovering in the air to witness the deeds of God and men.”
