A fundamental, profound review of the key issues relating to the early universe and the physical processes that occurred in it. The interplay between cosmic microwave background radiation, large scale structure, and the dark matter problem are stressed, with a central focus on the crucial issue of the phase transitions in the early universe and their observable consequences: baryon symmetry, baryogenesis and cosmological fluctuations. There is an interplay between cosmology, statistical physics and particle physics in studying these problems, both at the theoretical and the experimental / observational levels. Special contributions are devoted to primordial and astrophysical black holes and to high energy cosmic rays and neutrino astrophysics. There is also a special section devoted to the International Space Station and its scientific utilization.

It is naturally important for any of us to have a correct view of the universe we are in. Having realized that the Newtonian world-view is untenable, this book joins others that are searching for an alternative world-view. It is unique in using quantum physics to promote this search.One aim of the book is to present a lucid exposition of quantum mechanics in terms accessible to the general reader. Another aim is to show that realism (the belief that the outside world exists “from its own side” regardless of acts of consciousness) and locality (the belief that nothing moves faster than light) are invalid, and should be replaced by a new paradigm according to which the universe is alive. A third aim is to show that the thinking of quantum physicists evokes the philosophies of Plato and Plotinus.The revised edition will include a conversation between two fictional characters to elucidate the discussion of the meaning of wave functions.

Includes bibliographical referrences and index.

This book offers an inside look into the notoriously tumultuous, professional relationship of two great minds: Karl Popper and Paul Feyerabend. It collects their complete surviving correspondence (1948-1967) and contains previously unpublished papers by both. An introduction situates the correspondence in its historical context by recounting how they first came to meet and an extensive editorial apparatus provides a wealth of background information along with systematic mini-biographies of persons named. Taken together, the collection presents Popper and Feyerabend’s controversial ideas against the background of the postwar academic environment. It exposes key aspects of an evolving student-mentor relationship that eventually ended amidst increasing accusations of plagiarism. Throughout, readers will find in-depth discussions on a wide range of intriguing topics, including an ongoing debate over the foundations of quantum theory and Popper’s repeated attempts to design an experiment that would test different interpretations of quantum mechanics. The captivating exchange between Feyerabend and Popper offers a valuable resource that will appeal to scientists, laymen, and a wide range of scholars: especially philosophers, historians of science and philosophy and, more generally, intellectual historians.

This collection of five essays by Germany’s most prominent and influential social thinker both links Luhmann’s social theory to the question “What is modern about modernity?” and shows the origins and context of his theory. In the introductory essay, “Modernity in Contemporary Society,” Luhmann develops the thesis that the modern epistemological situation can be seen as the consequence of a radical change in social macrostructures that he calls “social differentiation,” thereby designating the juxtaposition of and interaction between a growing number of social subsystems without any hierarchical structure. “European Rationality” defines rationality as the capacity to see the difference between systems and their environment as a unity. Luhmann argues that, in a world characterized by contingency, rationality tends to become coextensive with imagination, a view that challenges their classical binary opposition and opens up the possibility of seeing modern rationality as a paradox. In the third essay, “Contingency as Modern Society’s Defining Attribute,” Luhmann develops a further and probably even more important paradox: that the generalization of contingency or cognitive uncertainty is precisely what provides stability within modern societies. In the process, he argues that medieval and early modern theology can be seen as a “preadaptive advance” through which Western thinking prepared itself for the modern epistemological situation. In “Describing the Future,” Luhmann claims that neither the traditional hope of learning from history nor the complementary hope of cognitively anticipating the future can be maintained, and that the classical concept of the future should be replaced by the notion of risk, defined as juxtaposing the expectation of realizing certain projects and the awareness that such projects might fail. The book concludes with “The Ecology of Ignorance,” in which Luhmann outlines prospective research areas “for sponsors who have yet to be identified.”
