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.

Michio Kaku: Now because computer power keeps doubling every 18 months, it means that that will affect biology; specifically genomics, meaning that within 10 years time, I expect us to have a CD-ROM with every single gene in our body costing about $1,000.  Today, to sequence every gene in your body would cost $50,000.  That is the cheapest you can sequence every single gene in your body.

Because of Moore's Law because things are being computer powered, it will be cheaper and cheaper, it means that within a 10-year period of time it means that that genomics will cost may be just about a  thousand dollars and that will be the basis of all your medicine.  Which means that we'll be able to scan millions of genomes with a computer that can create a revolution in how we numerically analyze genes.  For example, let's say we have a million old people and a million young people, we sequenced genes of old people, sequenced the genomes of young people because all of them have a CD-ROM, and we subtract.  That allows you to isolate where aging takes place, specifically which genes are damaged in the aging process.

Think of a car.  Where does aging take place car?  Well, the engine, why?  Because that's where combustion takes place, that's where we have the gum of deposits and soot buildup in the engine because that's where oxidation takes place.  But where does oxidation takes place in itself?  The mitochondria.  The mitochondrion is the engine of the cell.  So we now know where aging takes place.  And by scanning the genes, we can look at the genes of the mitochondria and be able to repair some of those genes.  And that could open up a whole new realm of biology.  In other words, biology will be reduced to computer science.
