Abstract
November 2013 marked the 50th anniversary of the premiere of Doctor Who, the longest-running science fiction television series in history (790 episodes spanning 1963–1989 and 2005–present). The revival of the BBC series in 2005 has been both critically acclaimed and commercially successful. The travels of the 900-plus year-old Time Lord and his companions introduce viewers to the past, present, and future of our planet and many others. While the series is obviously fictional, there is also a surprising amount of fairly accurate science as well.
