The Art Of Time Travel

No matter how practised we are at history, it always humbles us. No matter how often we visit the past, it always surprises us. Winner of the Ernest Scott Prize and Shortlisted for the NSW Premier's Literary Award for Non-fiction 'A rare feat of imagination and generosity.' – Mark McKenna With every sentence they write, historians must walk the tightrope between discipline and imagination, empathy and evidence. In this landmark work, eminent historian and award-winning author Tom Griffiths shares his passion for the fascinating, complex craft of history – or, as he calls it, the art of time travel. In fourteen portraits, Griffiths illuminates how historians such as Inga Clendinnen, Judith Wright, Geoffrey Blainey and Henry Reynolds have approached their craft. In prose both earthy and elegant, he shows the new insights they have brought to Australian history, and in so doing reshapes our shared knowledge of this continent. The Art of Time Travel is an exhilarating book that will forever change the way you think of Australia's past. 'If the past is a foreign country, Tom Griffiths makes the perfect travelling companion. Let him be your eyes and ears on our shared history. Most of all, follow his heart.' – Clare Wright

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.

A brilliant light coming through Peoria's bedroom window startles her to a trembling state - suddenly she is lifted up into a portal and time-travels into the era 1847 England from 2019 America. She can't get anyone to believe her in England until she goes back to 2019 and brings back one of her published books to prove she indeed lives in another era. Her friend, Jetty holds her hand one night and goes with her to England - they get lost in time-travel and struggle to find their way back home.

An authoritative chronicling of real-life time travel experiments, teleportation devices and more.

The topic of time travel provides tantalizing conundrums to consider for STEM experts and sci-fi creators alike. Most scientists and mathematicians agree that time travel by humans is probably impossible, yet they have not been able to offer conclusive proof. This book describes how the very nature of time remains a fascinating and complex subject, whether viewed from the perspective of Einstein's relativity or the nanoscale realm of quantum physics. Readers will recognize notable fictional works in literature, film, and television in which time travel serves as a useful plot device as well as a means of examining human history and contemporary social issues.

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.
