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.

How the Moon Changed the Course of the Civil War

Stonewall Jackson, the legendary Confederate commander, was killed by friendly fire at the moment of his greatest triumph. As darkness set in following Jackson's flanking attack on the Union Army at the Battle of Chancellorsville, a North Carolina regiment mistook the general for the enemy, calling out "It's a damned Yankee trick! Fire!"

Eight days later when Jackson succumbed to pneumonia, Robert E. Lee lost not only an invaluable military asset; it was also a significant blow to Southern morale. 

Ever since then, historians have been trying to figure out how such a monumental mistake could have been made. Two astronomers have now made a convincing case that the position of the moon was to blame. Using battle maps and astronomical software, astronomers Don Olson and Laurie E. Jasinski plotted exactly where Jackson and the North Carolina troops were at 9pm on May 2, 1863. 

"Stonewall Jackson would have been seen as a dark silhouette, from the point of view of the 18th North Carolina regiment," Olson said.

The astronomers have published their findings in the current issue of Sky & Telescope magazine.

Of course, the moon has played a significant role in many other historical events, from the fall of Athens to Columbus's subjugation of the Jamaican natives
