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.

Nanotechnology Already Swimming In Your Dairy. Did You Know?

What's the Latest?

The Project on Emerging Nanotechnologies has identified 96 food products currently on the shelves of US grocery stores which contain microscopic pieces of metal. "Examples include Dannon Greek Plain YogurtSilk Original Soy MilkRice Dream Rice Drink, Hershey's Bliss Dark Chocolate, and Kraft's iconic American Cheese Singles, all of which now contain nano-size titanium dioxide." The nano particle titanium dioxide is used as color enhancer, brightening bright colors and darkening the already-darks. As of 2008, only eight American food products were known to contain nano particles, representing a tenfold increase in just six years. 

What's the Big Idea?

The obvious question is whether it is safe for humans to consume these tiny particles? The FDA both recognizes that nano materials function differently than their macroscopic versions and that there are no plans to slow or regulate their introduction into the food supply. In 2012, the FDA released a draft statement concerning the need for a future regulatory framework: "[S]o-called nano-engineered food substances can have significantly altered bioavailability and may, therefore, raise new safety issues that have not been seen in their traditionally manufactured counterparts." Do you know what's in your yogurt?
