I came across this lecture recently by Hans Rosling, a social scientist. This lecture is stunning not only because it debunks the most widely held myths about people and economy around the world; it is a tour de force of the best data presentation that I have ever seen, anywhere anytime. It is worthwhile seeing if you are a scientist who wants to communicate complicated data.
