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.

Election Notes: Who Will Be Romney's Running Mate?

March 29, 2012, 2:24 PM

Mitt Romney will win the nomination. Rick Santorum’s victory in Louisiana only delayed the inevitable. Santorum gained just 5 delegates in Louisiana on Romney, who is still 295 delegates ahead. Romney has won 55% of the delegates available so far, and needs just 45% of the remaining delegates to clinch the nomination. Newt Gingrich is out of money and looks increasingly like a vanity candidate. With Romney running well ahead in the upcoming state of Wisconsin, there’s little reason to believe anyone wil be able to catch him.

 With the excitement out of the race, the question becomes who Romney will choose as his running mate. The political futures market Intrade considers Florida senator Marco Rubio the heavy favorite, giving him a 33% chance of getting the nod. Speculation that Rubio would be the pick increased yesterday when he announced that he was endorsing Romney. Rubio is perhaps not coincidentally releasing an autobiography in June, just as the primaries are wrapping up. Rubio has said he won’t run, but former Florida governor Jeb Bush—himself a subject of some vice presidential speculation—says he thinks Rubio would be the best choice. As the son of Cuban immigrants, Rubio—who has announced he is working on a new version of the DREAM Act—might help win back Latino voters alienated by the Republican position on immigration.

If Rubio isn’t the pick, speculators are betting it will be one of three governors: either New Jersey governor Chris Christie, Virginia governor Bob McDonnell, or New Mexico governor Susana Martinez. Both Wisconsin congressman and Republican budget architect Paul Ryan and Kentucky senator and presidential candidate Ron Paul’s son Rand Paul have also been the subjects of a fair amount of speculation. And traders give Romney a 3% chance of trying to shore up his support among conservatives by picking Santorum as his running mate.

“I think [Obama’s aides’] assessment is that Romney is much less a threat to them as events are a threat to them, and I agree with that. Romney cannot beat Obama, only events can beat Obama.”—James Carville
