P. J. E. Peebles Bücher

What lies at the heart of physical inquiry? This work delves into foundational ideas and assumptions that shape natural science, exploring principles guiding research and how scientists gauge the direction of their theories. It raises questions about the nature of physical theories: do they approximate an objective reality, or are they merely useful summaries of experimental results? Nobel Prize winner Jim Peebles draws on his extensive experience as a physicist to engage with these classic debates in the philosophy of science, using the development of physical cosmology as a case study. He begins by examining the evolution of thought in the physical sciences since Einstein, ultimately articulating the fundamental working assumptions of physics. Through a detailed exploration of the general theory of relativity, Einstein’s cosmological principle, the big bang theory, and our current understanding of the universe, Peebles argues that physical theories serve as useful approximations to an objective reality that science is gradually uncovering. This essential reflection on the nature and practice of science offers illuminating insights for cosmologists, physicists, and scholars in the history, philosophy, and sociology of science.

The book offers an insightful exploration of the evolution of cosmology, tracing its roots from Einstein's general theory of relativity to contemporary understandings of the universe. P.J.E. Peebles, a leading figure in the field, shares his firsthand experiences and contributions to key discoveries, including the roles of helium and microwave radiation from the big bang. He highlights the collaborative nature of scientific progress, detailing both significant breakthroughs and missteps, while also addressing the current gaps in cosmological theory and future research avenues.

The work of a Nobel Prize-winning physicist delves into the intricate relationship between science and society. It explores groundbreaking concepts in physics while addressing their profound implications for our understanding of the universe. Through engaging narratives and thought-provoking insights, the author invites readers to consider the ethical dimensions of scientific discovery and the responsibility of scientists in shaping the future. This book serves as both an intellectual journey and a call to reflect on the impact of scientific advancements on humanity.
