David Layzer

Eminent Harvard astrophysicist David Layzer offers readers a unified theory of natural order and its origins, from the permanence, stability, and orderliness of sub-atomic particles to the evolution of the human mind. Cosmogenesis provides the first extended account of a controversial theory that connects quantum mechanics with the second law of thermodynamics, and presents novel resolutions of longstanding paradoxes in these theories, such as those of Schroedinger's cat and the arrow of time. Layzer's main concerns in the second half of the book are with the philosophical issues surrounding science. He develops a highly original reconciliation of the conflict between traditional scientific determinism and the intuitive notion of individual freedom. He argues that although the elementary processes underlying biological evolution and human development are governed by physical laws, they are nevertheless genuinely creative and unpredictable.

Modern physics, which had its beginnings in the inclined-plane experiments of Galileo, deals with the measurable aspects of the world about us. The laws and definitions of classical physics are, at least superficially, differential equations in which each variable represents the result of a particular kind of measurement. These variables are usually called physical quantites. Starting from a few general laws and definitions we can derive formally further relations between the physical quantities and their rates of change in space and time. If the original definitions are self-consistent and the original laws accurate, the relations we derive from them should enable us to predict what the numerical result of a certain measurement will be whenever certain other measurements have yielded specified numerical results.
