Fractals and Scaling in Finance: Discontinuity, Concentration, Risk. Selecta Volume E Hardcover – Illustrated, 18 Sept. 1997

Without judging the merit of the content or the contribution to science of the author, this book is unreadable.There is literally no effort to structure the content in any logical way to walk the reader slowly. Terms are constantly used only to find them defined few pages later.As an illustration he uses the terms cup-convex and cap-convex. I was left completely confused about these meant, and I thought for a while these were special form of convexity. But no, all they mean is regular convex and concave. Few chapters later in a footnote the author says that he could have never been able to understand the difference between these two (like something you learn in High School) so he made up his own terminology.This might sounds like nothing but when you read about a complex topic and you’re serious about it, it is deeply frustrating to lost valuable time to understand the simple things. There are reason we are taught in math to use a very precise language, to avoid any unnecessary confusion, and this book is plagued with it.
