Historian David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. Totally worth your time.
From the TEDTalks description: "This is "Big History": an enlightening, wide-angle look at complexity, life and humanity, set against our slim share of the cosmic timeline."
Dr. Christian recently announced his initiative, The Big History Project, to teach big history to secondary school students in Australia and the United States. We need initiatives such as this, especially at a time when Creationism incessantly tries (and succeeds) to nudge its way into classrooms.
