This was an "iffy" for me. This book was difficult at times to read that I did have to go back and re-read things, mainly because this is very new material to me. I have never heard of fractals until I have read this and I did learn a bit. You can tell that this book was compiled, by the help of several other mathematicians, experienced in the branch of fractals. The only thing about fractals is that they are not studied as much as other subjects within the area of mathematics. Hence, they are rare and only about...maybe 100-ish individuals study this.
