# Mu-Ency - The Encyclopedia of the Mandelbrot Set

This is a picture from the Mandelbrot Set, one of the most well-known fractal images in the world. (Click it for a larger version). The Mandelbrot Set is one of my hobbies, and I have collected a large amount of information about it. To organize that information I have created Mu-Ency, a large collection of text files linked to each other1.

Here are some entries from Mu-Ency:

• History: How the Mandelbrot Set was discovered, how it became popular, etc.
• Exploring: The many things you can expect to find when you explore on your own.
• Area: I have been involved in finding the area of the Mandelbrot Set. Here are the latest results.
• Algorithms: How to compute the Mandelbrot Set and how to draw it.
• R2 Naming System: I have also developed a rather precise (and complex) naming system for features of the Mandelbrot Set. Mu-Ency presents many examples of this naming system.

More Pictures:

Some entries with pictures of parts of the Mandelbrot Set are: R2, Cusp, Embedded Julia set, 2-fold Embedded Julia set, 4-fold Embedded Julia set, Paramecia, R2.C(0), R2.C(1/3), R2.1/2.C(1/2), R2t series, Seahorse Valley, Delta Hausdorff Dimension, Exponential Map, Color, Representation Function, Reverse Bifurcation.

... or just explore on your own using DEMZ.

You can look up specific articles in the index, or see what's new in the changelog.

1 : "text files linked to each other" : Mu-Ency began as a glossary in 1988, intended to be accessed by sending commands by email message to a server that sends plain-text responses. Its source language remains in RHTF, my human-friendly style annotation like Markdown but far more capable.
