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.

Perl Founder Larry Wall Explains His Po-Mo Creation

August 9, 2010, 12:00 AM

Larry Wall, the father of Perl programming language, says that the language he created in 1987 is very "post-modern." Like po-mo architecture, for instance, Perl "collects features from other languages, things that seem to be distinct ways of doing things, and finds a way of meshing those in a pleasing fashion—the same way a poet might take words that are very different from each other and mesh them into a coherent poem." Thanks to Wall's background in linguistics, Perl is also much more like a natural language than most computer languages. 

In his Big Think interview, Wall explained the basics of computer programming using the analogy of cooking with a recipe. At its most basic, a computer program will first "list out various things that you're going to be dealing with," followed by "some instructions that say what to do with those ingredients." Like the head chef, the programmer is in control of the overall operation, but the computer acts like a sous chef, who can be trained to do simple repetitive actions, thereby taking over "the boring bits of our thinking." 

Wall also told us the five programming languages that everyone should know, and talked about the story behind his three virtues of a programmer: laziness, impatience, and hubris. Hobbits from The Lord of the Rings really are the ideal model for successful programmers, he said. "A hobbit is lazy in a very industrious way; a hobbit is very impatient in a very patient way; and a hobbit is proud in a very humble way." 

Apple tries hard to be the arbiter of good taste, Wall says, which isn't necessarily a bad thing. "The world would be a much poorer place without Apple as part of the cultural ecosystem, but we also need the other people who keep that from being the only way to do things. Because when good taste becomes mandatory, then it's not really good taste any more; it's just manners."

And for anyone wanting to write code more like Larry Wall, he also told us about his work habits, likes, and dislikes
