Review of the hardback: 'A major strength of this book is its capture of the expertise of four leading exponents of stochastic resonance research. Four heads here certainly provide an optimal performance. Take home messages from all the chapters are provided in clear 'in a nutshell' summaries. … the authors have rendered a major service to a multi-disciplinary research community which can benefit from the clarity of exposition offered in this book. It is to be hoped that that community will repay its debt to these authors by taking forward wherever possible applications of stochastic resonance.' Contemporary Physics
