I was a bit doubtful when I picked up INTRODUCING Fractal Geometry
as to whether such a book could contain anything of use. Its quirky pictures make it look more like a comic strip than a book on mathematics. But surprisingly the format seems to work very well. Much of the useful information about a subject can be summarised in short pieces of text, but on its own such text would be excessively terse. The pictures in the book help to make a book that is easy to skim through, but still gives the reader a helpful introduction to the subject.
The book looks at the history of the subject, showing how many mathematicians came up with examples of fractals, but it took Benoit Mandelbrot to bring the subject together. There are then plenty of real-world examples of fractals, from mountains and blood circulation to stock market graphs and image compression. In fact I feel that maybe there were too many examples, some of which seemed only tenuously connected to the subject. But if you want a quick introduction to fractals then this book is ideal - and there's a list of further reading for those who want to go deeper into the subject
