Hans Rosling is one of my favorite social scientists. Mashable has a post Hans Rosling: 5 TEDTalks That Shaped My Worldview.
"Data visionary Hans Rosling has given nine TEDTalks over the years, focusing on global trends in health, economics and population growth. His favorite talks, naturally, keep an eye toward these global themes — from business in Africa to youth culture in China."
I've only seen a couple of the five he lists. I'm looking forward to viewing the others. Here are two of my favorite Rosling videos.
