Leonardo Fibonacci had not infected Italy with Hindu numerals after
growing up in what is now Algeria -- then these ideas might not
The secret of human progress is and always has been to
keep ideas moving, both so that they meet and mate with new ideas
and so that they escape suppression at home. As the philosopher
David Hume was the first to observe, China suffers from a
geographic disadvantage in this respect: It is too easy to unify.
When disunited it grows rich and innovative. But time and again
emperors, from the Ming to the Maoist, have been able to establish

its peninsulas and mountain ranges, is very hard to unify by

refugees from each other, keeping flames alive. The history of
technology is littered with examples of Europeans who fled from one
jurisdiction to another to a find a more congenial or generous
ruler: Columbus, Gutenberg, Voltaire, Einstein.
