This book is a short survey of modern biophysics. Indeed, some chapters in this book have very general character and very often the knowledge presented in these chapters is not deep enough. Size of this book, which was published in one volume only is its biggest limitation, because presented subject is very wide and consists of many different scientific disciplines.Anyway this book can be regarded as a good overview of the very wide and diverse subject. I really do not understand why so many people complain here so much.This is book about the principles of biophysics.
