Published by AAAS years ago and have been directing others since then. The joy of discovery doesn’t even have to come from work in my laboratory; reading a great paper in the literature is a thrill of which I never tire. So, I come to global science topics as a working scientist but a rank amateur when it comes to internationalism. However, I feel deeply that a scientist must go beyond his pleasure in his personal science and take some responsibility for the larger issues of the field. And so I did a little globetrotting last year. Most memorably, I went to Rwanda and India. The contrast between these countries is striking. One is a tiny country, with 8 million closely packed people; the other is a sprawling nation with a billion people. One is still deeply underdeveloped but emerging sprightly from the unimaginable hell of genocide; the other is an established and vibrant democracy on an economic takeoff platform. What I saw in these two countries led me to believe that liberating the spirit of entrepreneurship is a key to economic development. People are the same around the world; free them and they start expressing their individual creativity. I saw the beginnings of that liberation in Rwanda (see sidebar). There is no doubt that in India, as in China, the liberation is in full swing.
