Book Synopsis Quantum Gravity in a Laboratory? by : Nick Huggett
Download or read book Quantum Gravity in a Laboratory? written by Nick Huggett and published by Cambridge University Press. This book was released on 2023-06-30 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristic – Planck – energy scale of quantum gravity makes experimental access to the relevant physics apparently impossible. Nevertheless, low energy experiments linking gravity and the quantum have been undertaken: the Page and Geilker quantum Cavendish experiment, and the Colella-Overhauser-Werner neutron interferometry experiment, for instance. However, neither probes states in which gravity remains in a coherent quantum superposition, unlike – it is claimed – recent proposals. In essence, if two initially unentangled subsystems interacting solely via gravity become entangled, then theorems of quantum mechanics show that gravity cannot be a classical subsystem. There are formidable challenges to such an experiment, but remarkably, tabletop technology into the gravity of very small bodies has advanced to the point that such an experiment might be feasible in the near future. This Element explains the proposal and what it aims to show, highlighting the important ways in which its interpretation is theory-laden.

Book Synopsis Epistemology of Experimental Gravity - Scientific Rationality by : Nicolae Sfetcu
Download or read book Epistemology of Experimental Gravity - Scientific Rationality written by Nicolae Sfetcu and published by MultiMedia Publishing. This book was released on with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of gravitational tests from an epistemological perspective framed in the concept of rational reconstruction of Imre Lakatos, based on his methodology of research programmes. Unlike other works on the same subject, the evaluated period is very extensive, starting with Newton's natural philosophy and up to the quantum gravity theories of today. In order to explain in a more rational way the complex evolution of the gravity concept of the last century, I propose a natural extension of the methodology of the research programmes of Lakatos that I then use during the paper. I believe that this approach offers a new perspective on how evolved over time the concept of gravity and the methods of testing each theory of gravity, through observations and experiments. I argue, based on the methodology of the research programmes and the studies of scientists and philosophers, that the current theories of quantum gravity are degenerative, due to the lack of experimental evidence over a long period of time and of self-immunization against the possibility of falsification. Moreover, a methodological current is being developed that assigns a secondary, unimportant role to verification through observations and/or experiments. For this reason, it will not be possible to have a complete theory of quantum gravity in its current form, which to include to the limit the general relativity, since physical theories have always been adjusted, during their evolution, based on observational or experimental tests, and verified by the predictions made. Also, contrary to a widespread opinion and current active programs regarding the unification of all the fundamental forces of physics in a single final theory, based on string theory, I argue that this unification is generally unlikely, and it is not possible anyway for a unification to be developed based on current theories of quantum gravity, including string theory. In addition, I support the views of some scientists and philosophers that currently too much resources are being consumed on the idea of developing quantum gravity theories, and in particular string theory, to include general relativity and to unify gravity with other forces, as long as science does not impose such research programs.

This book was released on 2002-04-30 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this XVII Course of the International School of Cosmology and Gravitation devoted to "ADVANCES IN THE INTERPLAY BETWEEN QUANTUM AND GRAVITY PHYSICS" we have considered different aspects of the influence of gravity on quantum systems. In order to achieve this aim, in many lectures, seminars and discussions we have strengthened the interplay between gravity and quantum systems starting from the situation in the early universe based on astrophysical observations, up to the earthly based experiments with atom interferometry for probing the structure of space-time. Thus we have had timely lectures on the quantum field and horizon of a black hole including reviews of the problem of black holes thermodynamics and entropy, quantum information, quantum black holes, quantum evaporation and Hawking radiation, recent advances in stockastic gravity. We have also discussed quantum fluctuations in inflationary universe, quantum effects and reheating after inflation, and superplanckian energies in Hawking radiation. In this regard the subject of spinors in purely affine space-time and Dirac matter according to Weyl in the generalized theory of gravitation were developed . The dualism between space-time and matter has been deeply analyzed in order to see why, for general relativity, this is an obstacle for quantization of the theory. Also canonical Gravity and Mach's principle, torsion and curvature as commutator for Quantum Gravity and Dirac Geometry of real space-time were analysed, together with the problem of 5-Dimensional Projective Unified Field theory and Multidimensional Gravity and Cosmology.

Book Synopsis The American Lab by : C. Bruce Tarter
Download or read book The American Lab written by C. Bruce Tarter and published by JHU Press. This book was released on 2018-08 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In The American Lab, former LLNL director Bruce Tarter captures the spirit of the Laboratory and its reflection of the broader world in which it thrived. He identifies the major themes that have characterized science and technology in the latter half of the twentieth century--the growth and decline of nuclear warheads, the unprecedented rise of supercomputing technology, laser systems, fusion, and mass spectrometry. He illuminates the Cold War dynamic from the participants' point of view--an unusual and valuable perspective on nuclear history. The story of the laboratory is a tale of three eras. Although the Lab took its research vision from European Edward Teller, its modus operandi came almost exclusively from namesake Ernest Lawrence and was subsequently invented in-house by its scientists and staff. During its first two decades the Lab's focus was almost entirely on nuclear weapons research and development, with a few other smaller enterprises that were technically related to the nuclear weapons activities. In the 1970s and 1980s, the Laboratory, along with many others in the Department of Energy complex, expanded into civilian pursuits that included energy, environment, biology, and basic science. A major program in laser science and technology became a cornerstone of this period. The third era was initiated by the end of the Cold War and saw the transformation of the traditional nuclear weapons activities into the stockpile stewardship program along with the rapid growth of projects that can be broadly characterized as homeland security. Tarter's history/memoir of the Lawrence Livermore National Laboratory, provides an insider's examination of nuclear science in the Cold War and the technological shift that occurred after the fall of the Berlin Wall."--Provided by publisher.
