"What time is it?" "And what time is it through the human interstellar portal?" Amy and Fin know all about weird dreams... They get them all the time... What they don't know is that everyday life is about to change for them inextricably, and in so many ways... Ways that they could never have imagined? For one thing, they don't have the faintest idea about the human interstellar portal or their special genealogy and secret hidden powers. And for another, the missing Lorentz force law quantum equations written by James Maxwell in 1861 must be found! After Grandad Joseph’s accident, young Amy and Fin are about to find their true calling as they attempt to find something else by embarking on an amazing, fun-filled, and traveltastic adventure by commanding their secret capabilities faster than yesterday, and sooner than tomorrow! Because it's time... A time for new blood to flourish... A time to meet Poe... A time to greet Johnny Depp... A time to beseech Leonardo Da Vinci... A time to find the Teyler Museum of Wonder... A time to climb the Statue of Science and Art ... A time to go through... Just me and you... Through the Human Interstellar Portal! Come and enjoy Amy and Fin’s snap-shot introduction into the amazing world of time travel on their first cool, action-packed adventure through the human interstellar portal. Featuring the wonderfully idiosyncratic and charming Leonardo Da Vinci as himself, and the even more wonderfully unique Johnny Depp, as Jack Sparrow, and himself. A wonderful, action-packed time-travel adventure story for children, young adults, and even adults! Front cover logo: Ai Free Publication ® ™ is a UK Registered Trademark.

Even the most reluctant readers will be fascinated to read about how twin astronauts Scott and Mark Kelly are a different age because Scott spent a year living on the International Space Station. This book looks at how time travel has been thought of from ancient times to modern day. It even discusses what humans might do if they could travel in time. From string theory to Einstein's theory of relativity, Heisenberg's uncertainty principle to the grandfather paradox, and wormholes to quantum physics, everything time travel related is discussed here in easy-to-understand language and complimented by vivid artwork on every spread.

This fascinating and up-to-date tour of modern physics examines the mind-blowing possibility of journeying back and forth through time.

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.

All that stands between an evil villain and world domination is a pair of twelve-year-olds who just learned they’re time travellers. What could go wrong? Twins Pew and Basket Church dream of escaping the gloomy orphanage where they grew up. Or, even better, the return of their unknown parents. But even in their wildest dreams, they never imagined the truth. They can travel through time! Armed only with perplexing clues to their past and a time travel talisman that is key to their future, Pew and Basket embark on an epic quest. Their voyage takes them from battlefields to pirate colonies, all in a race to uncover the secrets of their family – and outsmart time’s greatest villain. History, adventure and mystery collide in this delightfully clever romp through space and time. Middle School: The Worst Years of My Life by James Patterson was a no. 1 New York Times bestseller 03/06/2011

Presents the current understanding of the nature of time and space, and an approachable explanation of Einstein's theory of special relativity; then goes on to connect these to possible time travel along with the accompanying paradoxes involved.

Take an extraordinary trip through some of the most fascinating discoveries of archaeology and physics, and learn that not only is time travel theoretically possible, but that future generations may actually be engaged in it. Unique to this book is a program which enables you to structure your own group investigation into a form of vivid mental time travel. For the skeptical . . . survey the evidence, then decide. Index.

A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” —Publishers Weekly

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.
