Download or read book Time Travel written by Nikk Effingham and published by Oxford University Press. This book was released on 2020-02-20 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are various arguments for the metaphysical impossibility of time travel. Is it impossible because objects could then be in two places at once? Or is it impossible because some objects could bring about their own existence? In this book, Nikk Effingham contends that no such argument is sound and that time travel is metaphysically possible. His main focus is on the Grandfather Paradox: the position that time travel is impossible because someone could not go back in time and kill their own grandfather before he met their grandmother. In such a case, Effingham argues that the time traveller would have the ability to do the impossible (so they could kill their grandfather) even though those impossibilities will never come about (so they won't kill their grandfather). He then explores the ramifications of this view, discussing issues in probability and decision theory. The book ends by laying out the dangers of time travel and why, even though no time machines currently exist, we should pay extra special care ensuring that nothing, no matter how small or microscopic, ever travels in time.

Download or read book Now and Then We Time Travel written by Fraser A. Sherman and published by McFarland. This book was released on 2017-01-11 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 400 films and 150 television series have featured time travel--stories of rewriting history, lovers separated by centuries, journeys to the past or the (often dystopian) future. This book examines some of the roles time travel plays on screen in science fiction and fantasy. Plot synopses and credits are listed for films and TV series from England, Canada, the UK and Japan, as well as for TV and films from elsewhere in the world. Tropes and plot elements are highlighted. The author discusses philosophical questions about time travel, such as the logic of timelines, causality (what's to keep time-travelers from jumping back and correcting every mistake?) and morality (if you correct a mistake, are you still guilty of it?).

Download or read book The Problem of Time written by Edward Anderson and published by Springer. This book was released on 2017-09-18 with total page 917 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a treatise on time and on background independence in physics. It first considers how time is conceived of in each accepted paradigm of physics: Newtonian, special relativity, quantum mechanics (QM) and general relativity (GR). Substantial differences are moreover uncovered between what is meant by time in QM and in GR. These differences jointly source the Problem of Time: Nine interlinked facets which arise upon attempting concurrent treatment of the QM and GR paradigms, as is required in particular for a background independent theory of quantum gravity. A sizeable proportion of current quantum gravity programs - e.g. geometrodynamical and loop quantum gravity approaches to quantum GR, quantum cosmology, supergravity and M-theory - are background independent in this sense. This book's foundational topic is thus furthermore of practical relevance in the ongoing development of quantum gravity programs. This book shows moreover that eight of the nine facets of the Problem of Time already occur upon entertaining background independence in classical (rather than quantum) physics. By this development, and interpreting shape theory as modelling background independence, this book further establishes background independence as a field of study. Background independent mechanics, as well as minisuperspace (spatially homogeneous) models of GR and perturbations thereabout are used to illustrate these points. As hitherto formulated, the different facets of the Problem of Time greatly interfere with each others' attempted resolutions. This book explains how, none the less, a local resolution of the Problem of Time can be arrived at after various reconceptualizations of the facets and reformulations of their mathematical implementation. Self-contained appendices on mathematical methods for basic and foundational quantum gravity are included. Finally, this book outlines how supergravity is refreshingly different from GR as a realization of background independence, and what background independence entails at the topological level and beyond.

Download or read book Aspects of Time for Recognizing Human Activities written by Noureldien Hussein and published by Noureldien Hussein. This book was released on 2020-12-01 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis contributes to the literature of understanding and recognizing human activities in videos. More specifically, the thesis draw line between short-range atomic actions and long-range complex activities. For the classification of the latter, the mainstream approach in literature is to divide the activity into a handful of short segments, called atomic actions. Then, a neural model, such as 3D CNN, is trained to represent and classify each segment independently. Then, the activity-level classification probability scores are obtained by pooling over that of the segments. Differently, this work argues that long-range activities are better classified in full. That is to say, the neural model has to reason about the long-range activity, all at once, to better recognize it. Based on this argument, the thesis proposes different methods and neural network models for recognizing these complex activities.

Download or read book Time Travel written by David Wittenberg and published by Fordham University Press. This book was released on 2016-01-01 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book argues that time travel fiction is a narrative “laboratory,” a setting for thought experiments in which essential theoretical questions about storytelling—and, by extension, about the philosophy of temporality, history, and subjectivity—are represented in the form of literal devices and plots. Drawing on physics, philosophy, narrative theory, psychoanalysis, and film theory, the book links innovations in time travel fiction to specific shifts in the popularization of science, from evolutionary biology in the late 1800s, through relativity and quantum physics in the mid–20th century, to more recent “multiverse” cosmologies. Wittenberg shows how increasing awareness of new scientific models leads to surprising innovations in the literary “time machine,” which evolves from a “vehicle” used chiefly for sociopolitical commentary into a psychological and narratological device capable of exploring with great sophistication the temporal structure and significance of subjects, viewpoints, and historical events. The book covers work by well-known time travel writers such as H. G. Wells, Edward Bellamy, Robert Heinlein, Samuel Delany, and Harlan Ellison, as well as pulp fiction writers of the 1920s through the 1940s, popular and avant-garde postwar science fiction, television shows such as “The Twilight Zone” and “Star Trek,” and current cinema. Literature, film, and TV are read alongside theoretical work ranging from Einstein, Schrödinger, and Stephen Hawking to Gérard Genette, David Lewis, and Gilles Deleuze. Wittenberg argues that even the most mainstream audiences of popular time travel fiction and cinema are vigorously engaged with many of the same questions about temporality, identity, and history that concern literary theorists, media and film scholars, and philosophers.

Download or read book New Horizons in Time Domain Diffuse Optical Spectroscopy and Imaging written by Yoko Hoshi and published by MDPI. This book was released on 2020-06-23 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jöbsis was the first to describe the in vivo application of near-infrared spectroscopy (NIRS), also called diffuse optical spectroscopy (DOS). NIRS was originally designed for the clinical monitoring of tissue oxygenation, and today it has also become a useful tool for neuroimaging studies (functional near-infrared spectroscopy, fNIRS). However, difficulties in the selective and quantitative measurements of tissue hemoglobin (Hb), which have been central in the NIRS field for over 40 years, remain to be solved. To overcome these problems, time-domain (TD) and frequency-domain (FD) measurements have been tried. Presently, a wide range of NIRS instruments are available, including commonly available commercial instruments for continuous wave (CW) measurements, based on the modified Beer–Lambert law (steady-state domain measurements). Among these measurements, the TD measurement is the most promising approach, although compared with CW and FD measurements, TD measurements are less common, due to the need for large and expensive instruments with poor temporal resolution and limited dynamic range. However, thanks to technological developments, TD measurements are increasingly being used in research, and also in various clinical settings. This Special Issue highlights issues at the cutting edge of TD DOS and diffuse optical tomography (DOT). It covers all aspects related to TD measurements, including advances in hardware, methodology, the theory of light propagation, and clinical applications.
