The personal journeys of world-changing thinkers such as Leonardo Da Vinci are fascinating enough in their own right, but what happens when you track the paths of thousands of similarly influential individuals across space and time? A team of scientists have done exactly that, mapping the birthplaces and death sites of over 120,000 of history's most celebrated intellectuals from the past 2,600 years. The resulting 5-minute-long video — while it focuses primarily on the travels of European and American men — offers a great look at how human migration patterns shifted along with technology, and reinforces the enduring popularity of cities as cultural destinations across time. It's also got some surprises (guess which Southern state became a popular destination late in the 20th century?).
