I’ve been taking a look at some more of the TED talks that I mentioned a couple of weeks ago. Tonight I’ve watched the talk by Hans Rosling, a public health expert, and director of the Sweedish Karolinska Institute. In this talk he uses his Gapminder software to show that the separation between the third world and the first world is not what it once was. There are some fascinating examples of how the world is changing. You can explore more of the statistics at the Gapminder site.
