Information and Its Role in Nature presents an in-depth interdisciplinary discussion of the concept of information and its role in the control of natural processes. After a brief review of classical and quantum information theory, the author addresses numerous central questions, including: Is information reducible to the laws of physics and chemistry? Does the Universe, in its evolution, constantly generate new information? Or are information and information-processing exclusive attributes of living systems, related to the very definition of life? If so, what is the role of information in classical and quantum physics? In what ways does information-processing in the human brain bring about self-consciousness? Accessible to graduate students and professionals from all scientific disciplines, this stimulating book will help to shed light on many controversial issues at the heart of modern science.

This book is a new edition of Roederer's classic Dynamics of Geomagnetically Trapped Radiation, updated and considerably expanded. The main objective is to describe the dynamic properties of magnetically trapped particles in planetary radiation belts and plasmas and explain the physical processes involved from the theoretical point of view. The approach is to examine in detail the orbital and adiabatic motion of individual particles in typical configurations of magnetic and electric fields in the magnetosphere and, from there, derive basic features of the particles' collective "macroscopic" behavior in general planetary environments. Emphasis is not on the "what" but on the "why" of particle phenomena in near-earth space, providing a solid and clear understanding of the principal basic physical mechanisms and dynamic processes involved. The book will also serve as an introduction to general space plasma physics, with abundant basic examples to illustrate and explain the physical origin of different types of plasma current systems and their self-organizing character via the magnetic field. The ultimate aim is to help both graduate students and interested scientists to successfully face the theoretical and experimental challenges lying ahead in space physics in view of recent and upcoming satellite missions and an expected wealth of data on radiation belts and plasmas.

This introductory text deals with the physical systems and biological processes that intervene in what we broadly call "music. " We shall analyze what obj- tive, physical properties of sound patterns are associated with what subjective, psychological sensations of music. We shall describe how these sound patterns are actually produced in musical instruments, how they propagate through the environment, and how they are detected by the ear and interpreted in the brain. We shall do all this by using the physicist's language and his method of thought and analysis-without, however, using complicated mathematics. Although no previous knowledge of physics, physiology, and neurobiology is required, it is assumedthatthereaderpossesseshigh-schooleducationandisfamiliarwithbasic aspects of music, in particular with musical notation, scales and intervals, musical instruments and typical musical "sensations. " Books are readily available on the fundamentals of physics of music (e. g. , Benade, 1990; Pierce, 1983; Fletcher and Rossing, 1998; Johnston, 2003) and psychoacoustics, music psychology and perception (e. g. , Plomp, 1976; Deutsch, 1982a; Zatorre and Peretz, 2001; Hartmann, 2005). An excellent text on musical acoustics is that of Sundberg (1991), still most useful 17 years later; comp- hensive discussions of recent researches on pitch perception and related au- tory mechanisms can be found in Plack et al. (2005). The purpose of the present volume is not to duplicate but to synthesize and complement existing literature.
