'The Cosmic Microwave Background by Slobodan Perovic and Milan M. Cirkovic is a very welcome addition to the recent literature on the history and philosophy of experiment. The central focus is on the role that the discovery of the Cosmic Microwave Background (CMB) played in the establishment of the currently accepted 'hot big bang' theory of the origin of the universe. The authors also devote considerable discussion to the explanations of the CMB provided by alternative models of the origin, illustrating the complex relation between evidence and theory in cosmology. The discussion of the historical and philosophical issues is clear and well-written and will be understandable and valuable to those who are not expert in physics and cosmology. I strongly recommend it.' Allan Franklin, University of Colorado, Boulder
'Perović and Ćirković weave a fascinating and nuanced tapestry of history and epistemology. Not only is the historical narrative valuable in its own right, but the book really shines because of the pay-offs for both philosophers and physicists that arise from its rich historical analysis. The real story of the cosmic microwave background, in all its gritty detail, ultimately provides an even stronger methodological underpinning than the pristine textbook version that the authors set out to rectify.' Niels Martens, Utrecht University
