"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.

Ryan Wasserman explores a range of fascinating puzzles raised by the possibility of time travel, with entertaining examples from physics, science fiction, and popular culture, and he draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, laws of nature, persistence, change, and mereology.
He believes in science, but only magic can help his mom. Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books—and to his best friend, Gabi—to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time. Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic. "This is an incredible book, no matter which time universe you're in. I couldn't put it down. One of my favorite debut novels of the year."—Erin Entrada Kelly, New York Times bestselling author and 2018 Newbery Medal winner
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.
Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This is the original 1988 edition and contains columns published from 1974-1976.
Inspired at an impressionable age by the work of science fiction writers H.G.Wells and Arthur C Clarke, Paul Davies has thought long and hard about ways to travel in time. Here, the best-selling popular science writer finally reveals how it can be done - without breaking the laws of physics and without causing any earth-shattering paradoxes. Since time is money, time travel is a costly business. But with the help of a handy black hole, or better a wormhole, and a bit of luck, Davies's guide illustrates how this new mode of travel could yet be a viable option. "An entertaining tour around a fascinating topic, conducted by a world-class physicist" - SUNDAY TELEGRAPH
In 1687 Isaac Newton ushered in a new scientific era in which laws of nature could be used to predict the movements of matter with almost perfect precision. Newton's physics also posed a profound challenge to our self-understanding, however, for the very same laws that keep airplanes in the air and rivers flowing downhill tell us that it is in principle possible to predict what each of us will do every second of our entire lives, given the early conditions of the universe. Can it really be that even while you toss and turn late at night in the throes of an important decision and it seems like the scales of fate hang in the balance, that your decision is a foregone conclusion? Can it really be that everything you have done and everything you ever will do is determined by facts that were in place long before you were born? This problem is one of the staples of philosophical discussion. It is discussed by everyone from freshman in their first philosophy class, to theoretical physicists in bars after conferences. And yet there is no topic that remains more unsettling, and less well understood. If you want to get behind the façade, past the bare statement of determinism, and really try to understand what physics is telling us in its own terms, read this book. The problem of free will raises all kinds of questions. What does it mean to make a decision, and what does it mean to say that our actions are determined? What are laws of nature? What are causes? What sorts of things are we, when viewed through the lenses of physics, and how do we fit into the natural order? Ismael provides a deeply informed account of what physics tells us about ourselves. The result is a vision that is abstract, alien, illuminating, and-Ismael argues-affirmative of most of what we all believe about our own freedom. Written in a jargon-free style, How Physics Makes Us Free provides an accessible and innovative take on a central question of human existence.
LEAP INTO THE FUTURE, AND SHOOT BACK TO THE PAST H. G. Wells’s seminal short story “The Time Machine,” published in 1895, provided the springboard for modern science fiction’s time travel explosion. Responding to their own fascination with the subject, the greatest visionary writers of the twentieth century penned some of their finest stories. Here are eighteen of the most exciting tales ever told, including “Time’s Arrow” In Arthur C. Clarke’s classic, two brilliant physicists finally crack the mystery of time travel—with appalling consequences. “Death Ship” Richard Matheson, author of Somewhere in Time, unveils a chilling scenario concerning three astronauts who stumble upon the conundrum of past and future. “Yesterday was Monday” If all the world’s a stage, Theodore Sturgeon’s compelling tale follows the odyssey of an ordinary joe who winds up backstage. “Rainbird” R.A. Lafferty reflects on what might have been in this brainteaser about an inventor so brilliant that he invents himself right out of existence. “Timetipping” What if everyone time-traveled except you? Jack Dann provides some surprising answers in this literary gem. . . . as well as stories by Poul Anderson • L. Sprague de Camp • Joe Haldeman • John Kessel • Nancy Kress • Henry Kuttner • Ursula K. Le Guin • Larry Niven • Charles Sheffield • Robert Silverberg • Connie Willis By turns frightening, puzzling, and fantastic, these stories engage us in situations that may one day break free of the bonds of fantasy . . . to enter the realm of the future: our future. Note: "A Sound of Thunder" by Ray Bradbury and "I'm Scared" by Jack Finney are not included in this edition.

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.
