I have only limited and out-of-date experience with this. I know when I was setting up a friends business webpage here in Canada about a year ago, I was told that while it was cheaper to register in this country, it would take a lot longer for the registered name to propogate outside the country and it might not be as widely recognized than a US registered site. That was with the ".com" domain. I understand that using the country domains like ".ca", ".fr" etc, would allow nameservers to follow paths to designated nameservers for each country or region, but we were talking about using ".com" or ".org" and I wasn't sure how these get shared if they are registered in a country other than the U.S. Cheers, Noel - - - ------------------------------------------------------------ Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------ Date: Tue, 17 Mar 1998 14:37:01 +0000 From: mklein@bhv.ipnet.de Subject: (fractint) Trying Something Biological Hi to everybody ! Since to release of the fractint version 18.x (don't remember exact which one) I have always enjoyed to look at those great pictures. As the times passed by and with the growth of my theoretical knowledge of the theory of fractals an idea aroused in my mind. I tried to understand the mathematics behind all those beautiful pictures but soon I saw that my mathematical borders were reached. And at this point I will piont out my idea: I'm studing biology at germany and imaging that one day every biologist will use the mathematics as a tool for their interpretations. So what I wanted to do is to build a formula that represents a biological process, say somethink like a real prey-predator model, and calculate it in the complexe plane. Is there anybody who is interested in this idea and willing to help me ?

One warning, this is an ugly script and I'm sure that there are better ways to do it, but it does work. First it creates a temporary script and puts a bunch of calls to xfractint into it. Then it runs the script that it generated and saves all of the images into files.

It looks like I started with a Newton equation and then added a little bit of random formulizationizating. However, after translating them into Fractint formulas they still make some very nice images and the formulas are fun to experiment with. Paul Carlson frm:Newt_Fnc_Mset {; Copyright (c) Paul W.

Thanks for the info, Kerry! Am I correct in my interpretation that the shape of the main cardioid is therefore *not* a 'perfect' cardioid? I.e., the method I described of rotating one circle around another at my webpage < http://boralf.agsci.colostate.edu/~jason/fracpages/geo_mset.htm > will not accurately describe the actual Mset? If this is the case... well, there'll be some rethinking to do, at least!
