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.

Liquid Nitrogen Makes Delicious Ice Cream

July 16, 2013, 1:51 PM

While making ice cream with liquid nitrogen is nothing new, it's taking off like never before during the scorching hot summer of 2013. 

"This is the next thing in ice cream," says the ice cream consultant (now that sounds like a fun job!) Darryl David. It's not hard to see why. The natural element can be used to make ice cream on the spot, without any preservatives, and this technique also involves the wow effect that helps attract customers.

In this Science Xplained video, Dr. Ainissa Ramirez shows us the chemistry at work and how this technique can be safely replicated at home by using salt.

Dr. Ainissa Ramirez (@blkgrlphd) is a materials scientist turned science evangelist, who is passionate about getting kids of all ages excited about science. Before taking on this call, she was an associate professor of mechanical engineering & materials science at Yale University.  She has published numerous scientific articles and wrote the book Save Our Science by TED Books on how to inspire the next generation with science.  Currently, she is writing a book on the science behind football with NYT best selling author Allen St. John called Newton’s Football (Random House).
