I recently watched this documentary series and thought it quite interesting. Big history isn't really “history” in the traditional sense, but tries to see historical events in the context of science, somewhat similar to the way Jared Diamond uses Guns, Germs, and Steel to explain human developmental patterns. The project was developed with the Big History Project supported by Bill Gate’s foundation.
There are 17 episodes in all, but most of them are short episodes. Time may pass faster than you think.
