This book is a historical account of how natural philosophers and scientists have endeavoured to understand the universe at large, first in a mythical and later in a scientific context. Starting with the creation stories of ancient Egypt and Mesopotamia, the book covers all the major events in theoretical and observational cosmology, from Aristotle''s cosmos over the Copernican revolution to the discovery of the accelerating universe in the late 1990s. It presentscosmology as a subject including scientific as well as non-scientific dimensions, and tells the story of how it developed into a true science of the heavens. Contrary to most other books in the history of cosmology, it offers an integrated account of the development with emphasis on the modernEinsteinian and post-Einsteinian period. Starting in the pre-literary era, it carries the story onwards to the early years of the 21st century.

This book introduces the methodological and philosophical problems with which modern history of science is concerned, offering a comprehensive and critical review through description and evaluation of significant historiographical viewpoints. Incorporating discussion of key problems in general historical writing, with examples drawn from a range of disciplines, this non-elementary introduction bridges the gap between general history and history of science. Following a review of the early development of the history of science, the theory of history as applied to science history is introduced, examining the basic problems which this generates, including problems of periodisation, ideological functions, and the conflict between diachronical and anachronical historiography. Finally, the book considers the critical use, and analysis, of historical sources, and the possibility of the experiemental reconstruction of history. Aimed primarily at students, the book's broad scope and integration of historical, philosophical and scientific matters will interest philosophers, sociologists and general historians, for whom there is no alternative introduction to the subject at this level.

Entropic Creation is the first English-language book to consider the cultural and religious responses to the second law of thermodynamics, from around 1860 to 1920. According to the second law of thermodynamics, as formulated by the German physicist Rudolf Clausius, the entropy of any closed system will inevitably increase in time, meaning that the system will decay and eventually end in a dead state of equilibrium. Application of the law to the entire universe, first proposed in the 1850s, led to the prediction of a future 'heat death', where all life has ceased and all organization dissolved. In the late 1860s it was pointed out that, as a consequence of the heat death scenario, the universe can have existed only for a finite period of time. According to the 'entropic creation argument', thermodynamics warrants the conclusion that the world once begun or was created. It is these two scenarios, allegedly consequences of the science of thermodynamics, which form the core of this book. The heat death and the claim of cosmic creation were widely discussed in the period 1870 to 1920, with participants in the debate including European scientists, intellectuals and social critics, among them the physicist William Thomson and the communist thinker Friedrich Engels. One reason for the passion of the debate was that some authors used the law of entropy increase to argue for a divine creation of the world. Consequently, the second law of thermodynamics became highly controversial. In Germany in particular, materialists and positivists engaged in battle with Christian - mostly Catholic - scholars over the cosmological consequences of thermodynamics. This heated debate, which is today largely forgotten, is reconstructed and examined in detail in this book, bringing into focus key themes on the interactions between cosmology, physics, religion and ideology, and the public way in which these topics were discussed in the latter half of the nineteenth and the first years of the twentieth century.

The 2011 Nobel Prize in Physics was awarded for the discovery of cosmic acceleration due to dark energy, a discovery that is all the more perplexing as nobody knows what dark energy actually is. We put the modern concept of cosmological vacuum energy into historical context and show how it grew out of disparate roots in quantum mechanics (zero-point energy) and relativity theory (the cosmological constant, Einstein's “greatest blunder”). These two influences have remained strangely aloof and still co-exist in an uneasy alliance that is at the heart of the greatest crisis in theoretical physics, the cosmological-constant problem.
