TED Talk

Today in class we took the entire 55 minutes to watch a 7 minute TED Talk video. It was very interesting, nonetheless. The first video was about population pyramids and how they can be used to estimate how fast a country will grow or die out. The second video was about Hans Rollings (That may not be his name), a man who calculates how much a country grows and their wealth. He showed a graph abut how every country progressed over the years.
