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.

Getting A Wireless Connection Under The Sea

What's the Latest Development?

University of Buffalo researchers recently dropped two 40-pound sensors into the waters of Lake Erie just off Buffalo and sent a command to them using a laptop on the ground. The series of chirps that resulted marked a major step in their development of a wireless underwater Internet that uses sound waves to transmit data directly to computers and smartphones. The system will differ from previous versions in that it eliminates the surface buoys used to convert sensors' sound waves to radio waves, which are then sent to computers via a satellite.

What's the Big Idea?

Several different organizations, including the National Oceanic and Atmospheric Administration, use sound wave-based systems to receive underwater data, but different infrastructures make sharing that data difficult. The University of Buffalo system would eliminate that problem by creating a worldwide standard. In addition to marine data collection, an underwater Internet could help improve tsunami warning systems, spot illegal submarine drug traffic, and aid in searches for sources of oil and natural gas. The researchers will present their project next month at the ACM International Conference on Underwater Networks and Systems.
