I just love TED talks.. so much information in single talk.. that makes you think and strive for more..
Again one of best talks of TED (all are marvelous).. listen here Prof. Rosling talking about golbal poverty and means to achieve it and the goal to achieve. Extremely informational and fully based on statistically sound data and one of best endings you will see for such talk.
About this Talk (From TED.com)
In a follow-up to his now-legendary TED2006 presentation, Hans Rosling demonstrates how developing countries are pulling themselves out of poverty. He shows us the next generation of his Trendalyzer software -- which analyzes and displays data in amazingly accessible ways, allowing people to see patterns previously hidden behind mountains of stats. (Ten days later, he announced a deal with Google to acquire the software.) He also demos Dollar Street, a program that lets you peer in the windows of typical families worldwide living at different income levels. Be sure to watch straight through to the (literally) jaw-dropping finale.
