Thus, to readers who are passionate about their research, this book provides a very appropriate perspective and a systematic approach to many relevant questions, directly related to the conscious choice of pursuing a scientific life. It was a pleasure to read and provides clear answers to many a `Why' associated with scientific research across disciplines.The author in my view provides a well thought-through `rough guide' to be considered by many a scientist. It should be shared with colleagues, students, and even people in the street, general society, management entities, and decision makers of higher academic institutions and in government: specifically, with those who so often query with variable modes and emphasis `Why is scientific research (really) necessary?'- Andreas Roodt, Journal of Applied Crystallography, 52, 2019This is an enjoyable book that provides a unique perspective of a mentor in the field of academic science. The author's passion for science is evident throughout. -Chery Thompson, Case Western Reserve University School of MedicineMany of the issues are illustrated and, in turn illuminated, by way of well-chosen case examples often involving the good and great (Darwin, Einstein, Fleming, Watson and Crick) and also including many from John Helliwell’s own research; this is a highly commendable feature of the book.- Paul Barnes (2019): The Whys of a Scientific Life, Crystallography Reviews, DOI:10.1080/0889311X.2019.1624315
