This is a mesmerizing time-lapse map of the 2053 nuclear explosions–all but two of them tests–since 1945. It really picks up in the 1960s. You see an icon for each country as they begin testing–first the US, then Russia, followed by England, France, China, and finally Pakistan–with a running total for each country (about half of the explosions were done by the US). It’s about 15 minutes long, but fascinating. You see where each explosion occurred (lots in the South Pacific by the US and France).
