Mass and Motion in General Relativity
217,00 CHF *
ggf. zzgl. Versand

Our current perspective has arisen over millennia, through falling apples, elevator thought experiments and stars spiralling into black holes; Free fall and self-force in general relativity. In fact, we do not have in mind to make a 1:1 reflection of the school. The ordering has been rearranged to tie articles together more coherently. We also propose to ask authors to focus their contributions according to the title we have suggested and to give a more complete description of current and future directions. We expect this will add to the volume’s value for all anticipated readers. This volume has the unique feature of presenting a multifaceted approach to mass, which is intended mainly for graduate students and young doctoral researchers in the field of gravitation, who might be hoping to find a concise and introductory presentation of advanced topics outside their research field. It is true that research from the infinitesimal scale of particle physics to the cosmic scale of the universe is concerned with the mass. While there have been spectacular advances in physics during the past century, mass still remains as a mysterious entity at the forefront of current research. Particle accelerators in the quest for the Higgs boson, laser interferometers sensitive enough to respond to gravitational waves, equivalence principle tests and detectors for dark matter are among the most ambitious and expensive experiments that fundamental physics has ever envisaged, and strongly attest to this fact. Both the self-force and radiation reaction are, in fact, lively topics of research. Related to the nature of motion, they have been hotly debated within general relativity from the inception of the theory. Recent developments have shown that radiation reaction is unavoidable in determining the gravitational waveforms emitted from a source such as the capture of a solar mass star by super-massive black hole (EMRI). The main theme of this volume is mass and its motion within general relativity (and other theories of gravity), particularly for compact bodies, to which many articles directly refer. Within this framework, there are chapters on post-Newtonian and related methods (Blanchet, Gourgoulhon and Jaramillo, Nagar, Schäfer), as well as on the self-force approach to the analysis of motion (Barack, Detweiler, Gal’tsov, Poisson, Wald, Whiting), summarised along with an historic development of the field (Spallicci) and a snapshot on the state of the art (Burko). Note that self-acceleration depends directly on the mass of the body experiencing it. Mass itself is essential for this effect on motion. Auxiliary chapters set the context for these theoretical contributions within the wider context of experimental physics. The space mission LISA (Jennrich) has been designed to detect the gravitational waves from EMRI captures, while other LISA sources may have electromagnetic counterparts (van Putten). Motion in modern gravitation must confront alternative theories (Esposito-Farèse) and it must to be comprehensible within a quantum context (Noui), and demands an account of the relation between vacuum fluctuations and inertia (Jaekel and Reynaud). A volume centred on the fundamental role of mass in physics should face issues related to the basic laws of mechanics proposed by Newton (Lämmerzahl) and precision measurements (Davis). The role of the Higgs boson within physics is to give a mass to elementary particles (Djouadi), by interacting with all particles required to have a mass and thereby inducing inertia. Moreover, most mass in the universe is dark, and only indirectly detected. A proposed alternative to dark matter theories is due to a modified theory of gravity (Esposito-Farèse) such as MOND (MOdified Newtonian Dynamics). Even if general relativity does not explain gravity, there still remains the fundamental problem of reconciling any theory of gravity with the physics of quantum fields (Noui), itself so well verified experimentally.

The Sungod's Journey through the Netherworld

'The ancient Egyptian sources come alive, speaking to us without seeming alien to our modern ways of thinking. Andreas Schweizer invites us to join the nocturnal voyage of the solar barque and to immerse ourselves, with the 'Great Soul' of the sun, into the darkness surrounding us. Here in the illustrations and texts of the Amduat, threats hidden in the depths of our soul become visible as concrete images, an analysis of which remains ever worthwhile: even in the guise of the evil, ominous, or dark side of godhead with which Schweizer concerns himself. The netherworld into which we descend underlies our own world. Creative energies of dreadful intensity are active there, and only death, to which all must surrender, makes us truly alive by offering us regeneration from the depths.'—Erik Hornung, from the Foreword The Amduat (literally 'that which is in the netherworld') tells the story of the nocturnal journey of Re, the Egyptian Sungod, through the netherworld from the time when the sun dies, after setting in the west, to its rebirth at sunrise in the east. In the middle of the night, in the profoundest depths of the netherworld, this resurrection is made possible by a mystical union of the sun with the mummified body of Osiris, god of the dead. This great mystery of the union between the freely moving soul of the Sungod, longing for the bright and boundless sky, with Osiris's corpse, which is irrevocably bound to the subterranean realm of the dead, evokes the renewal of all life and the restoration of totality. In the Egyptian belief system, the pharaohs and in later times all blessed dead embarked on this same 'night-sea journey' after death, ultimately becoming one with Re and living forever. The vision of the afterlife elaborated in the Amduat, dating from around 1500 B.C.E., has been influential for millennia, providing the model for an entire genre of Egyptian literature, the Books of the Afterlife, which in turn endured into the Greco-Roman era. Its themes and images persisted into gnostic and alchemical texts and made their way into early Christian portrayals of the beyond. In The Sungod's Journey through the Netherworld, Andreas Schweizer guides the reader through the Amduat, offering a psychological interpretation of its principal textual and iconographic elements. He is concerned with themes that run deep and wide in human experience, drawing on Jungian archetypes to find similar expression in many cultures worldwide: sleep as death; resurrection as reawakening or rebirth; and salvation or redemption, whether from original sin (as for Christians) or from the total annihilation of death (as for the ancient Egyptians).
