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.

Big Think: Will discoveries made using the LHC have any practical applications?

Peter Woit: The general problem with particle physics is that these questions we are asking are happening at such high energy scales in such short distances that it's very hard to see how to do anything very practical with this. I mean, anything - like the particle we are talking about often have lifetimes which are 10 to the minus 20 seconds. I mean, there just - If you produce a Higgs particle it's going to be so short lived it's incredibly difficult to see any evidence of the thing. It's not something that you're going to be able to go out and use these Higgs particles to carry around and do something with.

On the other hand, you don't really know what you're going to find, if you do find. Especially if you find something - I guess I could say it this way. If you do just find this Higgs particle and this Higgs field, it's very hard to make or to do anything really practical with that. If you find some completely new understanding of this theory then who knows. You can conjecturably come up with all sorts of models. You can come up with models in which there's kind of new, heavy, long-lived particles which you can then imagine doing things with. I think it's a pretty good bet that within the near future, this is not really particularly practical. This is really not a - just trying to understand the world better, but not in a way that's particularly going to be useful for doing anything too practical that's going to affect people anytime soon

Today's Big Idea: The Theory of Everything

Physicists are in the process of working out the "Theory of Everything" that describes all the forces of nature. This was Einstein's great unfinished project, and yet it is still only in its infan... Read More…
