Available in PDF, EPUB and Kindle. Book excerpt: About the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith ("Time Travel"), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson (”Presentists should believe in time-travel”), Frank Arntzenius and Tim Maudlin ("Time Travel and Modern Physics"), and David Lewis (“The Paradoxes of Time Travel”). The article begins with an Introduction in which I make a short presentation of the time travel, and continues with a History of the concept of time travel, main physical aspects of time travel, including backward time travel in the past in general relativity and quantum physics, and time travel in the future, then a presentation of the Grandfather paradox that is approached in almost all specialized works, followed by a section dedicated to the Philosophy of time travel, and a section in which I analyze Causal loops for time travel. I finish my work with Conclusions, in which I sustain my personal opinions on the time travel, and the Bibliography on which the work is based.

Download or read book A Time Travel Dialogue written by John W. Carroll and published by Open Book Publishers. This book was released on 2014-08-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is time travel just a confusing plot device deployed by science fiction authors and Hollywood filmmakers to amaze and amuse? Or might empirical data prompt a scientific hypothesis of time travel? Structured on a fascinating dialogue involving a distinguished physicist, Dr. Rufus, a physics graduate student and a computer scientist this book probes an experimentally supported hypothesis of backwards time travel – and in so doing addresses key metaphysical issues, such as causation, identity over time and free will. The setting is the Jefferson National Laboratory during a period of five days in 2010. Dr. Rufus’s experimental search for the psi-lepton and the resulting intractable data spurs the discussion on time travel. She and her two colleagues are pushed by their observations to address the grandfather paradox and other puzzles about backwards causation, with attention also given to causal loops, multi-dimensional time, and the prospect that only the present exists. Sensible solutions to the main puzzles emerge, ultimately advancing the case for time travel really being possible. A Time Travel Dialogue addresses the possibility of time travel, approaching familiar paradoxes in a rigorous, engaging, and fun manner. It follows in the long philosophical tradition of using dialogue to present philosophical ideas and arguments, but is ground breaking in its use of the dialogue format to introduce readers to the metaphysics of time travel, and is also distinctive in its use of lab results to drive philosophical analysis. The discussion of data that might decide whether time is one-dimensional (one timeline) or multi-dimensional (branching time) is especially novel.
Download or read book Time Travel written by Nikk Effingham and published by Oxford University Press, USA. This book was released on 2020-02-20 with total page 260 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 How to Build a Time Machine written by Paul Davies and published by Penguin. This book was released on 2003-03-25 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: With his unique knack for making cutting-edge theoretical science effortlessly accessible, world-renowned physicist Paul Davies now tackles an issue that has boggled minds for centuries: Is time travel possible? The answer, insists Davies, is definitely yes—once you iron out a few kinks in the space-time continuum. With tongue placed firmly in cheek, Davies explains the theoretical physics that make visiting the future and revisiting the past possible, then proceeds to lay out a four-stage process for assembling a time machine and making it work. Wildly inventive and theoretically sound, How to Build a Time Machine is creative science at its best—illuminating, entertaining, and thought provoking.

Available in PDF, EPUB and Kindle. Book excerpt: A philosophical look at the movie Inception and its brilliant metaphysical puzzles Is the top still spinning? Was it all a dream? In the world of Christopher Nolan's four-time Academy Award-winning movie, people can share one another's dreams and alter their beliefs and thoughts. Inception is a metaphysical heist film that raises more questions than it answers: Can we know what is real? Can you be held morally responsible for what you do in dreams? What is the nature of dreams, and what do they tell us about the boundaries of "self" and "other"? From Plato to Aristotle and from Descartes to Hume, Inception and Philosophy draws from important philosophical minds to shed new light on the movie's captivating themes, including the one that everyone talks about: did the top fall down (and does it even matter)? Explores the movie's key questions and themes, including how we can tell if we're dreaming or awake, how to make sense of a paradox, and whether or not inception is possible Gives new insights into the nature of free will, time, dreams, and the unconscious mind Discusses different interpretations of the film, and whether or not philosophy can help shed light on which is the "right one" Deepens your understanding of the movie's multi-layered plot and dream-infiltrating characters, including Dom Cobb, Arthur, Mal, Ariadne, Eames, Saito, and Yusuf An essential companion for every dedicated Inception fan, this book will enrich your experience of the Inception universe and its complex dreamscape.
Download or read book Time Travel written by Paul J. Nahin and published by JHU Press. This book was released on 2011-04-01 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That’s just what Paul J. Nahin’s guide provides. An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin’s equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way. If you ever wanted to set up the latest and greatest grandfather paradox—or just wanted to know if the time-bending events in the latest pulp you read could ever happen—then this book is for you.

Download or read book Nonlinear Gravitodynamics written by Remo Ruffini and published by World Scientific. This book was released on 2003 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a detailed, up-to-date account of the Lense-Thirring effect and its implications for physics and astrophysics. Starting from a profound intuition of Lense and Thirring in 1918, based on a simple solution to the linearized Einstein field equations, this has emerged in the past four decades as a phenomenon of extraordinary importance in cosmology, radio jets in quasars, and the physics of neutron stars and black holes, besides leading to some of the most sophisticated experiments ever performed in the space surrounding our planet. The book contains the contributions presented at the ?Third William Fairbank Meeting?, which have been expanded by adding a complete set of classical and prominent contemporary papers on this subject and a general introduction by R Ruffini.
Download or read book Time Travel written by David Wittenberg and published by Fordham Univ Press. This book was released on 2016-01-01 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This “stimulating contribution to literary theory” reveals the deeply philosophical concerns and developments behind popular time travel sci-fi (London Review of Books). In Time Travel, literary theorist David Wittenberg argues that time travel fiction is not mere escapism, but a narrative “laboratory” where theoretical questions about storytelling—and, by extension, about the philosophy of temporality, history, and subjectivity—are presented in story form. Drawing on physics, philosophy, narrative theory, psychoanalysis, and film theory, Wittenberg links innovations in time travel fiction to specific shifts in the popularization of science, from nineteenth-century evolutionary biology to twentieth-century quantum physics and more recent “multiverse” cosmologies. Wittenberg shows how popular awareness of new science led to surprising innovations in the literary “time machine,” which evolved from a vehicle used for sociopolitical commentary into a psychological device capable of exploring the temporal structure and significance of subjects, viewpoints, and historical events. Time Travel draws on classic works of science fiction by H. G. Wells, Edward Bellamy, Robert Heinlein, Samuel Delany, and Harlan Ellison, television shows such as “The Twilight Zone” and “Star Trek,” and other popular entertainments. These are read alongside theoretical work ranging from Einstein, Schrödinger, 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 Elements of Causal Inference written by Jonas Peters and published by MIT Press. This book was released on 2017-11-29 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise and self-contained introduction to causal inference, increasingly important in data science and machine learning. The mathematization of causality is a relatively recent development, and has become increasingly important in data science and machine learning. This book offers a self-contained and concise introduction to causal models and how to learn them from data. After explaining the need for causal models and discussing some of the principles underlying causal inference, the book teaches readers how to use causal models: how to compute intervention distributions, how to infer causal models from observational and interventional data, and how causal ideas could be exploited for classical machine learning problems. All of these topics are discussed first in terms of two variables and then in the more general multivariate case. The bivariate case turns out to be a particularly hard problem for causal learning because there are no conditional independences as used by classical methods for solving multivariate cases. The authors consider analyzing statistical asymmetries between cause and effect to be highly instructive, and they report on their decade of intensive research into this problem. The book is accessible to readers with a background in machine learning or statistics, and can be used in graduate courses or as a reference for researchers. The text includes code snippets that can be copied and pasted, exercises, and an appendix with a summary of the most important technical concepts.
