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.

Why Afternoon is the Best Time to Exercise

December 15, 2012, 1:00 PM

What's the Latest Development?

Researchers at UCLA's Brain Research Institute believe that exercising at the right time of day may contribute to a well-regulated body clock thanks to higher levels of protein production in the brain. Their new conclusions are the result of experiments in which mice exercised at different times during the day. "After several weeks of running, the animals’ internal clocks were sturdier. Messages now traveled to these animals’ hearts and livers far more frequently than in their sedentary counterparts. The beneficial effect was especially pronounced in those animals that exercised in the afternoon (or mouse equivalent)."

What's the Big Idea?

While scientists can't say for sure that humans should exercise in the afternoon rather than the morning (any exercise is better than none), they do recommend against exclusively late-night activity: "Unpublished results from [the study] show that healthy mice running at the animal equivalent of 11 p.m. or so developed significant disruptions in their circadian rhythm. Among other effects, they slept poorly." Still, if you wish to sleep well and avoid physical ailments associated with aging or clumsy circadian rhythm, exercise remains a very good idea.
