You may or may not be aware that a new Batman film is about to appear in cinemas [SPOILER ALERT: It's called The Dark Knight Rises].
Perhaps you feel that you don't understand enough about this "Batman" thing. Here is some help:
1) In a paper entitled "Trajectory of a falling Batman" graduate physicists at the University of Leicester ask whether the Batman's cape would, as depicted in Batman Begins, enable him to glide. [SPOILER ALERT: It wouldn't.]
2) The Finnish loss-making mobile-phone company Nokia has published a series of three-dimensional maps of Gotham City. [SPOILER ALERT: It's a bit like New York.] More Gotham topographical resources here.
3) Nice Catherine Shoard, of the Guardian, considers the politics of Batman [SPOILER ALERT: They're a bit right-wing.]
4) LogoDesignLove links to a video and some well-researched writing on the Batman logo. [SPOILER ALERT: Pointy ears.]
5) Batman is kind of gay, or at least fairly bi-curious. (One commenter points out: "... just because hew has no permanent relationship with a woman does not mean he's a homosexual,he can not put a woman in his life due to his oath in fighting crime" [sic, passim]. That's what they used to say about Edward Heath, too.)
Hope that all helps.
UPDATE: At the Telegraph, Robert Colvile agrees with Catherine Shoard but thinks Batman's right-wing views should be celebrated. (I thought conservatism was all about respecting social institutions: Batman uses his wealth to ignore them. Puzzling.)
