This is an introductory survey to the philosophy of science suitable for beginners and nonspecialists. Its point of departure is the question: why should we believe what science tells us about the world? In this attempt to justify the claims of science the book treats such topics as observation data, confirmation of theories, and the explanation of phenomena. The writing is clear and concrete with detailed examples drawn from contemporary science: solar neutrinos, the gravitational bending of light, and the creation/evolution debate, for example. What emerges is a view of science in which observation relies on theory to give it meaning and credibility, while theory relies on observation for its motivation and validation.

The concept of observability of entities in physical science is typically analyzed in terms of the nature and significance of a dichotomy between observables and unobservables. In this book, however, this categorization is resisted and observability is analyzed in a descriptive way in terms of the information which one can receive through interaction with objects in the world. The account of interaction and the transfer of information is done using applicable scientific theories. In this way the question of observability of scientific entities is put to science itself. Several examples are presented which show how this interaction-information account of observability is done. It is demonstrated that observability has many dimensions which are in general orthogonal. The epistemic significance of these dimensions is explained. This study is intended primarily as a method for understanding problems of observability rather than as a solution to those problems. The important issue of scientific realism and its relation to observability, however, demands attention. Hence, the implication of the interaction-information account for realism is drawn in terms of the epistemic significance of the dimensions of observability. This amounts to specifying what it is about good observations that make them objective evidence for scientific theories.

The concept of gravity provides a natural phenomenon that is simultaneously obvious and obscure; we all know what it is, but rarely question why it is. The simple observation that 'what goes up must come down' contrasts starkly with our current scientific explanation of gravity, which involves challenging and sometimes counterintuitive concepts. With such extremes between the plain and the perplexing, gravity forces a sharp focus on scientific method. Following the history of gravity from Aristotle to Einstein, this clear account highlights the logic of scientific method for non-specialists. Successive theories of gravity and the evidence for each are presented clearly and rationally, focusing on the fundamental ideas behind them. Using only high-school level algebra and geometry, the author emphasizes what the equations mean rather than how they are derived, making this accessible for all those curious about gravity and how science really works.

"This book offers an excellent explanation of the scientific method and its use, through case studies from astronomy, physics, and philosophy. Summing Up: Recommended. Lower- and upper-division undergraduates. General readers."CHOICE"In summary this is a lovely, elegant book which reminds us that physics is not an exercise in mathematics but a self-consistent system of thought based on measurement and informed observation which depends on interpretation by the human mind in the context of the science of the day. It is a valuable reminder of the underlying human quality in physics that gets lost in the 'shut up and calculate' methodology of the more esoteric branches of the science."The ObservatoryWe know the Earth rotates, but how do we know? When and how did it become reasonable to believe that the Earth rotates?This book offers a historical account, from ancient Greek science to the theory of relativity and ultimately to videos taken from outer space, of how this widely known truth came to be. Using an accessible and entertaining narrative suitable for anyone interested in astronomy, physics, or the history of either, Kosso clarifies the use of evidence to prove that the Earth rotates, and deals with the tension between the claims that the Earth is absolutely in motion, yet all motion is relative. The book also explores the general nature of scientific evidence and method, and confronts challenges to science from outside the discipline.

A Summary of Scientific Method is a brief description of what makes science scientific. It is written in a direct, clear style that is accessible and informative for scientists and science students. It is intended to help science teachers explain how science works, highlighting strengths without ignoring limitations, and to help scientists articulate the process and standards of their work. The book demonstrates that there are several important requirements for being scientific, and the most fundamental of these is maintaining an extensive, interconnected, coherent network of ideas. Some components in the network are empirical, others are theoretical, and they support each other. Clarifying the structure of this web of knowledge explains the role of the commonly cited aspects of scientific method, things like hypotheses, theories, testing, evidence, and the like. A Summary of Scientific Method provides a clear, intuitive, and accurate model of scientific method.
