"This is a book that contains very few numbers. Instead, it is about meeting people who have opened my eyes." It was facts that helped him explain how the world works. But it was curiosity and commitment that made the late Hans Rosling, co-author of the bestselling book Factfulness , the most popular researcher of our time. How I Learned to Understand the World is Hans Rosling's own story, which he wrote while working on Factfulness in the months before his death, of how he became a revolutionary thinker, and takes us from the swelter of an emergency clinic in Mozambique, to the World Economic Forum at Davos. In collaboration with Swedish journalist Fanny Hargestam, Hans Rosling wrote his memoir with the same joy of storytelling that made a whole world listen when he spoke.
