A number and a flower
Ive previously mentioned media critic Phil Sandifer, who since early 2011 has been blogging his way through every episode of Doctor Who (plus related phenomena) from 1963 to the present. (The reference to a psychochronograph in the recent Doctor Who episode Hide was a shout-out to Phils blog, which until recently was titled TARDIS Eruditorum: A Psychochronography in Blue.) Hes also been reworking the posts into chapters of a book series, the first three volumes of which (on the First, Second, and Third Doctors) have been published though you might want to hold off on buying the first one, since a revised edition will be available soon.
For the last ten months Phils been valiantly slogging through the vast interregnum of novels, audioplays, and spinoffs (in other words, stuff I have no familiarity with) between the end of the classic series in 1989 and its revival in 2005. Now he has finally gotten to Rose, the first episode of the revived series, and has revamped the website for the occasion. Heres the entry on Rose. Go read it! And heres some background on Rose. Go read that too.
