FRACTAL FAQ (FREQUENTLY ASKED QUESTIONS) ___________________________________________________________ ISSN Pending Volume 1 Number 1 February 13, 1995 ___________________________________________________________ (c) Copyright Ermel Stepp 1995 ___________________________________________________________ Introduction The international computer network Usenet contains discussions on a variety of topics. The Usenet newsgroup sci.fractals and the listserv forum fracl are devoted to discussions on fractals. This FAQ (Frequently Asked Questions) is an electronic serial compiled from questions and answers contributed by many participants in those discussions. This FAQ also lists various archives of programs, images, and papers that can be accessed through the global computer networks (WWW/Internet/BITNET) by using email, anonymous ftp, gophers, and World Wide Web browsers. This FAQ is not intended as a general introduction to fractals, or a set of rigorous definitions, but rather a useful summary of ideas, sources, and references. This FAQ is posted monthly to the Usenet groups sci.fractals, , , bit.listserv.fracl and the listserv forum fracl. Like most FAQs, it can be obtained free with a WWW browser or by anonymous ftp to ftp://rtfm.mit.edu/pub/usenet/news.answers/fractalfaq [18.181.0.24]; also, with a textbased browser, such as lynx, or anonymous ftp to: byrd.mu.wvnet.edu/pub/estepp/fracha/fractal.faq [129.71.32.152]. It can be retrieved by email to mailserver@rtfm.mit.edu with the message: send usenet/news.answers/fractalfaq The hypertext version of the Fractal FAQ has hyperlinks to sources on the World Wide Web. It can be accessed with a browser such as xmosaic at http://www.cis.ohiostate.edu/hypertext/faq/usenet/fractalfaq/faq.html. Also, the hypertext version is online for review and comment at: http://www.marshall.edu/~stepp/fractalfaq/faq.html. Please suggest other links to add to the Fractal FAQ. For your information, the World Wide Web FAQ is available via: The WWW: http://sunsite.unc.edu/boutell/faq/www_faq.html Anonymous ftp: rtfm.mit.edu in /pub/usenet/news.answers/www/faq Email: mailserver@rtfm.mit.edu (send usenet/news.answers/www/faq If you are viewing this file with a newsreader such as "rn" or "trn", you can search for a particular question by using "g^Qn" (that's lowercase g, up arrow, Q, and n, the number of the question you wish). Or you may browse forward using <controlG> to search for a Subject: line. I am happy to receive more information to add to this file. Also, let me know if you find mistakes. Please send your comments and suggestions to Ermel Stepp (email: stepp@marshall.edu). The questions which are answered are: Q1: I want to learn about fractals. What should I read first?
