Frost crystals forming a fractal pattern (from Wikipedia's article on fractals).
The new edition of the Waywords and Meansigns musical recording of Finnegans Wake will be out Tuesday (James Joyce's birthday), but while we wait for that, PQ has two new blog posts up about the book at his Wake blog, Finnegans Wake.
The first post, "What is Finnegans Wake? A Simulacrum of the Globe (Part 2)," argues that the book reproduces the Precession of the Equinoxes (you'll learn some astronomy reading the post.
The second post is "Mathematicians Confirm: Finnegans Wake is Fractal," and after you read it, you should probably read the article from the Guardian that inspired it.
The Guardian article says that academics ran a statistical analysis of more than 100 litereary works, and found that while many were in the structures of fractals, Finnegans Wake was the most multifractal of all in terms of its sentence structures.
A paragraph from the Guardian article:
The other works most comparable to multifractals, the academics found, were A Heartbreaking Work of Staggering Genius by Dave Eggers, Hopscotch by Julio Cortazar, The USA trilogy by John Dos Passos, The Waves by Virginia Woolf, 2666 by Roberto Bolaño and Joyce’s Ulysses. Marcel Proust’s À la recherche du temps perdu showed “little correlation” to multifractality, however; nor did Ayn Rand’s Atlas Shrugged.
