There have been three major eras in the history of science, as Johns Hopkins University astrophysicist and computer scientist Alex Szalay describes it. The first, which lasted for millennia, was empirical, involving mostly the recording of data: Chinese star charts, Leonardo da Vinci’s codices on how turbulent water flows, Tico Brahe’s recording of the motions…
At first blush, the key players in George Friedman’s World War III scenario seem to have been plucked from a random-country generator: Japan, Turkey, and… Poland?
But take a step back. First, consider the source. Friedman, 68, has been in the geopolitical strategy game for decades. He founded the Austin, Texas-based geopolitical intelligence firm Stratfor…
