The New York Times ’s James Glanz has called Steven Weinberg “perhaps the world’s most authoritative proponent of the idea that physics is hurtling toward a ‘final theory,’ a complete explanation of nature’s particles and forces that will endure as the bedrock of all science forevermore. He is also a powerful writer of prose that can illuminate—and sting... He recently received the Lewis Thomas Prize, awarded to the researcher who best embodies ‘the scientist as poet.’” Both the brilliant scientist and the provocative writer are fully present in this book as Weinberg pursues his principal passions, theoretical physics and a deeper understanding of the culture, philosophy, history, and politics of science.Each of these essays, which span fifteen years, struggles in one way or another with the necessity of facing up to the discovery that the laws of nature are impersonal, with no hint of a special status for human beings. Defending the spirit of science against its cultural adversaries, these essays express a viewpoint that is reductionist, realist, and devoutly secular. Each is preceded by a new introduction that explains its provenance and, if necessary, brings it up to date. Together, they afford the general reader the unique pleasure of experiencing the superb sense, understanding, and knowledge of one of the most interesting and forceful scientific minds of our era.

This is the third in a series of volumes of essays by Steven Weinberg, the previous two having also been published by HUP (Facing Up in 2001, and Lake Views in 2010). Weinberg, recipient of the Nobel Prize (1979) with Abdus Shalam and Sheldon Glashow for their contributions to the electroweak unification theory, is well known not only for his groundbreaking work in physics, but also for his efforts in popularizing science and the history of science, and for his stances on various matters in politics, public policy, and religion. This volume, like the previous two, runs a wide gamut, from the cosmological to the personal. Specific topics include particle physics, quantum mechanics, astronomy, big science, the history of science, space flight, science funding, the limits of current knowledge, and several other subjects ranging from the art of discovery to being wrong. Nearly all of the work included here, again as with the previous two volumes, has been previously published. The author has added introductions to the volume as a whole and to each essay, putting the material in context and adding further explanation where necessary. He has also added a number of explanatory notes.--
