I have for many years known Hans Rosling. He is a professor in Stockholm. He started working in rural Africa, described the Konzo nutritional disorder, and is now a not only an excellent teacher, but also global educator.
Please visit his homepage http://www.gapminder.org/ and download some of the very good software that he has developed. This software is free, and the teaching materials are useful tools to learn both students and professionals.
Now, please watch the film from YouTube (BBC Four):
Statistics come to life when Swedish academic superstar Hans Rosling graphically illustrates global development over the last 200 years.
