Maybe it is because I’m going to Africa in  a few weeks, or maybe I’m just a junky for people with ridiculously ambitious ideas, but I love people like Neil TurokturokHe is aiming to transform Africa into a player on the scientific landscape by launching new college institutes across Africa focused on math.  The guy should know what he is talking about, he is a physics professor at Cambridge and buddies with Stephen Hawking, but the idea of just going around and launching new colleges from nothing to transform something as dramatic as Africa’s future is inspiring.  Taking a step back, you have people as diverse as U2’s Bono, the quintessential rockstar, and a big time professor from Cambridge just leveraging their positions to enact big change.  Africa will be a different place in 20 years.
