Is the universe fine-tuned for complexity, life, or something else? This comprehensive overview of fine-tuning arguments in physics, with contributions from leading researchers in their fields, sheds light on this often used but seldom understood topic. Each chapter reviews a specific subject in modern physics, such as dark energy, inflation, or solar system formation, and discusses whether any parameters in our current theories appear to be fine-tuned and, if so, to what degree. Connections and differences between these fine-tuning arguments are made clear, and detailed mathematical derivations of various fine-tuned parameters are given. This accessible yet precise introduction to fine-tuning in physics will aid students and researchers across astrophysics, atomic and particle physics and cosmology, as well as all those working at the intersections of physics and philosophy.

Chemistry and Biochemistry of Flavoenzymes summarizes the present knowledge of the chemical and physical properties of free flavin, modified flavins occurring in nature, and deazaflavin. This information forms the fundamental basis for understanding the catalytic properties of flavoenzymes. Flavoproteins involved in transport, electron transfer, oxidation, dehydrogenation and hydroxylation reactions are discussed with respect to their biochemical and biophysical properties. The book presents the catalytic mechanisms of the flavoproteins in detail and, where available, three-dimensional structures and molecular biology data are included. The medical aspects of free and protein-bound flavin are also briefly discussed. Chemistry and Biochemistry of Flavoenzymes is an essential reference source for chemists, biochemists, toxicologists, biologists, pharmacologists, and researchers in the pharmaceutical industry.
In this historical volume Salvatore Califano traces the developments of ideas and theories in physical and theoretical chemistry throughout the 20th century. This seldom-told narrative provides details of topics from thermodynamics to atomic structure, radioactivity and quantum chemistry. Califano’s expertise as a physical chemist allows him to judge the historical developments from the point of view of modern chemistry. This detailed and unique historical narrative is fascinating for chemists working in the fields of physical chemistry and is also a useful resource for science historians who will enjoy access to material not previously dealt with in a coherent way.
