White noise is a random signal (or process) with a flat power spectral density. In other words, the signal's power spectral density has equal power in any band, at any center frequency, having a given bandwidth. White noise is considered analogous to white light which contains all frequencies.

The Thrilling Joke

When I entered the theater to watch The Dark Knight last summer, I had expectations since the previous Batman film had been the best one and director Chris Nolan seemed to be making the characters layered. What ended up happening was that I almost forgot Batman was in the movie and was completely emotionally vested in the bad guys, especially The Joker. Recently, Bandit told me that the character of the Joker in the film was inspired by a comic book called The Killing Joke. I just had to read it.

The Killing Joke is a short story about The Joker escaping from a mental asylum after he had been put there by Batman. The Joker proceeds to take revenge on Commissioner Gordon, to prove his theory that everyone is bad, and can be made to do bad things, if pushed hard enough. He makes it personal and his methods are so violent and dark, that it makes the film look like a children's Disney movie. The Joker takes over a theme park and turns it into a nest for all birds of dark feathers. There is also a chilling epilogue to the story, that doesn't involve any of the usual Batman villains, but a common man, like you and me.

Written by Alan Moore, it uses his parallel story-telling technique that he employed to great effect in the Watchmen; this time concentrating on The Joker's past, circumstances that led a sane man to become The Joker. A lot of the dialog in the film, especially those between The Joker and Batman were reminiscent of the movie. Questions are raised in the reader's mind whether the two characters are just two sides of the same coin. The illustrations by Brian Bollard, are very 3D-like, making the characters pop out of the book, and making it more real. The end, again, like Watchmen, champions the cause of the human spirit.
