I occasionally look up at one of the countless new skyscrapers rising up on cranes to prop up a grey London winter sky and wonder what it must be like to know how to build such a thing. 

Or how quantum mechanics work.  Or predict the weather.  Or divide a cell. 

We all think we know about these things.  And we do.  A bit.  

But most of know precious little in any detail about how the world truly works; we lull ourselves into a false sense of expertise based on what others have actually mastered.  

The good news: we're able to collaborate in ways that exponentially exceed our individual capabilities to create, discover and understand. 

The bad news: we're blind to our own ignorance.
