'The two great achievements in fundamental physics of the 20th century are quantum mechanics, embodied in the standard model of particle physics, and general relativity, Einstein's theory of gravity. Their reconciliation is the challenge that is addressed in these fascinating interviews with many of the leading experts. Superstring theory, also developed in the 20th century, is the leading candidate to provide the answer, but other ideas are being explored. The wide range of viewpoints presented gives the reader a sense of this profound challenge.' John H. Schwartz, Harold Brown Professor of Theoretical Physics, Emeritus, Caltech
'Conversations on Quantum Gravity is a unique resource for students and researchers of quantum gravity, for philosophers and sociologists of science, and for future historians of physics. Jacome Armas has admirably accomplished a herculean task: 37 interviews, peppered with his provocative questions informed by a broad appreciation of the scope of the physics problems and the panoply of approaches to solving them, and copiously referenced to the relevant literature.' Ted Jacobson, Distinguished University Professor, University of Maryland
'This book presents an unconventional ten-year 'long-exposure photograph' of the evolving research field of quantum gravity. In this field, there is potential for breakthroughs in interlinking diverse approaches, many of which are covered in this book. Thus the book provides an informative read to complement more specialised textbooks. It is suitable for students, researchers and anyone interested in learning what practitioners of quantum gravity consider as the critical obstacles to understanding quantum spacetime.' Astrid Eichhorn, CP3-Origins, University of Southern Denmark
' students and professionals will find the book an excellent portal into the field Highly recommended.' A. Spero, Choice Magazine
'As the title states, it consists of experts discussing their research, but at a level which should be accessible to all physicists who have a basic idea as to why a theory of quantum gravity is worth looking for. I recommend it highly to those and to future historians who want to know what those people were really thinking.' Phillip Helbig, The Observatory
' excellent for quantum gravity researchers, especially young ones ' Alexander S. Blum, Foundations of Physics
