Doesn't the volume get reduced by 20/27 in every step
]]>You asked for a little bit more.
I was actually looking for a detailed one although your explanation helped a lot.
Okay, you got it. After all what do Barnsley and Mandelbrot know anyway? The essence of fractals begins Isaac Newton and Arthur Cayley. Take a look at the drawing.
When Newton's method is applied to the equation x^3 - 1 = 0, the fractal in the image is created. See the x's those are the roots of equation. Now the red areas are all the initial conditions that converge on that root in the red. Same for the blue and yellow. No one ever imagined such structure in such a simple system until Arthur Cayley first tried to answer the question.
He had already solved it for x^2 - 1 = 0 and assumed that the cubic would only be slightly harder.
]]>A look at a map shows the coastline as a line that winds about apparently at random. If you view the map at increasing magnifications it still looks like that. You are perhaps expecting that the shape is exactly the same at all magnifications but I don't think that was what was meant when Benoit Mandlebrot first introduced the idea. I don't know the underlying math but you could make a start by looking at
http://en.wikipedia.org/wiki/Benoit_Mandelbrot
I couldn't find much math theory there and it seems you might have to read his book. Maybe you can get it from a library.
As for a fern, take a look at this picture. Each fern leaf is made up of minature ferns which are made up of even more minature ferns .......

]]>Doess anything on earth resemble a ideal fractal which infinitely repeats itself.
My brother argues that the coastline is an example of a fractal.
According to Benoit your brother is correct.
There's a book written by bobbym for example called "My Age and Other Interesting Facts" that doesn't exist. It weighs nothing as well as having zero volume.
Yes and it is equally interesting.

Come to think of it, I can think of lots of things that don't exist and also have zero volume.

Then there's the snowman I made last year. That was made from all the ice I could find when the temperature was 20 degrees C.
And the gin and tonic I make when I've got no tonic. Oh yes, I've got no gin either.
