Title: Meet Me Post by: alfarq on January 23, 2007, 01:37:48 AM Hi, all. I am a professional software developer. Computer graphics is purely a hobby, for me, as are fractals. I am reading Michael F. Barnsley's book "SuperFractals" and, frankly, find parts of it rather challenging. I am hoping to find an online forum of likeminded folk that could help me get through some of the tougher spots. Suggestions? alfarq Title: Re: Meet Me Post by: David Makin on January 23, 2007, 02:32:41 AM Hello and welcome !
Have you already read Barnsley's previous book on Fractals (the title escapes me at this moment) ? That may help fill in some blanks - as might looking at books by Pietgen and Saupe.

Greetings, and Welcome to this particular Forum !!! :D Michael Barnsley posted a message on this forum several months ago concerning this new book. But has never bothered responding to any of the comments to that original post by him, nor has he posted any other messages since. Which is too bad, since you could basically get your answers straight form the horse's mouth (so to speak). If you check around with second-hand book stores, you may be able to pick up on a good used copy of "Fractals Everywhere" that Michael wrote several years ago (try to find at least the second edition). It would assist as a reference point for reading his latest publication. Outside of that, exactly what areas were you having problems with??

In general: I have worked many of the exercises in the book, but have no way to check them. A more specific question... I am familiar with the idea of open sets of points not containing the points that define their extent, but I don't understand how this follows from the definition of open sets being the sets of a topology. I'll post other questions here as they come to me, unless you can a better place. -allen Title: Re: Meet Me Post by: lycium on January 29, 2007, 12:44:11 PM I am familiar with the idea of open sets of points not containing the points that define their extent, but I don't understand how this follows from the definition of open sets being the sets of a topology. big fat disclaimer: i failed real analysis at university :( it's ridiculous because i'm probably one of only a handful of people who remember anything about it! every open ball is an open set, and the definition of neighbourhoods relies upon finding points in these balls as the radius approaches zero. i can't remember exactly why the definitions are in terms of open balls rather than closed balls, and tbh i don't really understand clopen sets intuitively, but that's how it was formulated in my course. i can offer the (extremely lucid) notes from my real analysis course if you like - just email me :) hope that helps mate. welcome to the forums!
