The Big History series asks questions guaranteed to change the way you look at the past. Did Napoleon’s invasion of Russia come undone because of…tin buttons? Did New York become America’s biggest city because of…salt? How does the sinking of the Titanic power your cell phone? What’s the connection between ancient Egyptian mummies and a modern ham and cheese sandwich? By weaving science into the core of the human story, Big History takes familiar subjects and gives them a twist that will have you rethinking everything from the Big Bang to today’s headlines. The series creates an interconnected panorama of patterns and themes that links history to dozens of fields including astronomy, biology, chemistry, and geology. The first season ends with a two-hour finale that pulls everything we know about science and history into one grand narrative of the universe and us.
