The Fabric of the Cosmos the book, such as discussions revolving around classical physics, quantum mechanics, and cosmological physics. Chapter 2, "The Universe and the Bucket", features space as its key point. The question posed by Greene is this: "Is space a human abstraction, or is it a physical entity?" The key thought experiment is a spinning bucket of water, designed to make one think about what creates the force felt inside the bucket when it is spinning. The ideas of Isaac Newton, Ernst Mach, and Gottfried Leibniz on this thought experiment are discussed in detail. Chapter 3, "Relativity and the Absolute", focuses on spacetime.
European Physical Journal D European Physical Journal D The European Physical Journal D: Atomic, Molecular, Optical and Plasma Physics is an academic journal recognized by the European Physical Society, presenting new and original research results. The main areas covered are: The range of topics covered in these areas is extensive, from Molecular Interaction and Reactivity to Spectroscopy and Thermodynamics of Clusters, from Atomic Optics to Bose-Einstein Condensation to Femtochemistry. The EPJ D arose from various predecessors: "Il Nuovo Cimento (Section D)", "Journal de Physique", and "Zeitschrift für Physik D". Prior to 1998, this journal was named "Zeitschrift für Physik D: Atoms, Molecules and Clusters".
