I was not acquainted with any theories in the book: chaos theory, for example, as well as the author's works, so I was confused while reading this book.
The author writes widely on many topics, from mathematics to philosophy to the everyday life, and I can make out the usefulness of mathematics and physics in things we never thought deeply about... although, to the end, I am still overwhelmed. Yet, I appreciated the images included in the book, for they helped me visualize the concepts in a better way. I found great joy in looking at the pictures of the fractals, relating them to our heartbeats in the book, and go: "Now I know."
I will be re-reading the book so that I can understand the concepts better.
