 Fourier Title text: That cat has some serious periodic components

## Explanation

 This explanation may be incomplete or incorrect: Please include the reason why this explanation is incomplete, like this: `{{incomplete|reason}}`If you can address this issue, please edit the page! Thanks.

A Fourier transform is a mathematical function often used in physics and engineering.

## Transcript

[Cueball talks on phone. Cat with many sharp points looks on.]
Cueball: Hi, Dr. Elizabeth? Yeah, uh ... I accidentally took the Fourier transform of my cat ...
Cat: Meow!

## Trivia

• Original comments from Randall: "I like the idea of a graph meowing. Also, that cat has a lot of periodic components."
• This is the twenty-seventh comic originally posted to livejournal. The previous was 25: Barrel - Part 4. The next was 27: Meat Cereals.

# Discussion

Isn't the cat also imaginary because its Fourier transform isn't symmetric?

I feel like there's another joke in that his cat is "imaginary" or has complex components.

Might this also be a Garfield joke? Garfield's veterinarian is named Liz. Although Garfield, being roughly a three-dimensional ovoid, would probably end up with a much different looking Fourier transform than what is depicted here.

I think the transform may be of the movements of various parts of the cat. Cats tend to move their ears and heads a lot, and other parts, less so. What tipped me off is the spike at the tip of the tail. Cats typically twitch the very tip of their tail in a rhythmic fashion. 108.162.216.192 21:52, 2 March 2015 (UTC)
