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.

Injections At Supersonic Speed, Without Needles

Article written by guest writer Kecia Lynn

What's the Latest Development?

Researchers at the University of Twente in the Netherlands say they've come up with a method of drug injection that may be a viable alternative to needles. With the help of a laser pulse, tiny shockwaves expel a microjet of liquid at a speed of up to 2000 miles per hour -- about as fast as a supersonic jet -- easily penetrating the skin and delivering a precise amount into the body. 

What's the Big Idea?

Needles are by far the preferred method of injecting drugs, but they have their downsides, including possible disease transmission. Various alternatives have been developed and used over the years, many of which involve the same technique of forcing liquid into the body via some sort of pressure. Unfortunately if the dose isn't delivered properly, splashing can occur, ruining the injection. The amount of force used can also damage the skin. Concerning its method, the team still has additional research to do, including testing on a variety of actual people: So far the only tests have been done on gelatin covered with synthetic skin.
