Time-Symmetry Breaking in Turbulent Multi-Particle Dispersion
by Jennifer JuchaThis thesis presents experimental and theoretical investigations of the connection between the time asymmetry in the short-time evolution of particle clusters and the intrinsic irreversibility of turbulent flows due to the energy cascade. The term turbulence describes a special state of a continuous medium in which many interacting degrees of freedom are excited. One of the interesting phenomena observed in turbulent flows is their time irreversibility. When milk is stirred into coffee, for example, highly complex and interwoven structures are produced, making the mixing process irreversible. This behavior can be analyzed in more detail by studying the dispersion of particle clusters. Previous experimental and numerical studies on the time asymmetry in two-particle dispersion indicate that particles separate faster backwards than forwards in time, but no conclusive explanation has yet been provided. In this thesis, an experimental study on the short-time behavior of two- and four-particle dispersion in a turbulent water flow between two counter-rotating propellers is presented. A brief but rigorous theoretical analysis reveals that the observed time irreversibility is closely linked to the turbulence energy cascade. Additionally, it is demonstrated experimentally that the addition of minute amounts of polymers to the flow has a significant impact on multi-particle dispersion due to an alteration of the energy cascade.
Time, Tense, and Reference
by Aleksandar Jokic Quentin SmithAmong the many branches of philosophy, the philosophy of time and the philosophy of language are more intimately interconnected than most, yet their practitioners have long pursued independent paths. This book helps to bridge the gap between the two groups.
Time to Shine: Celebrating the World’s Iridescent Animals
by Karen JamesonLet yourself be dazzled by creatures around the world in this brilliant nonfiction picture book about iridescence. Have you ever noticed the rainbow-like shimmer on certain bird feathers, insect bodies and animal scales? This effect, called iridescence, changes depending on the angle from which its viewed, and animals across the globe use the effect to both blend in and stand out. In playful rhyming couplets, Time to Shine takes a closer look at these creatures and their sparkly “clothes,” from the mallard duck’s shining green flying “cap,” which allows the birds to coordinate flight movements, to the reed frog’s heat reflecting “vest,” to the hummingbird’s sequinned “costume,” which helps to attract a mate. A secondary level of prose text on each spread gives further context for each animal’s particular environment and adaptation. Light seems to dance off of the book's vibrant pages, with illustrations that bring us up close and personal with animals both exotic and familiar to young readers. An author’s note provides additional information about the science of iridescence. Key Text Features author's note bibliography definitions explanation facts further information illustrations Correlates to the Common Core State Standards in English Language Arts: CCSS.ELA-LITERACY.RL.1.5 Explain major differences between books that tell stories and books that give information, drawing on a wide reading of a range of text types.
Time Trapped
by Richard UngarThe high-octane sequel to Time Snatchers. Caleb thought he'd escaped Uncle's clutches and could have a normal life in 1968, but no such luck. After being forcibly returned to Timeless Treasures and his old job of stealing valuable objects from the past, he learns that things have gotten even more sinister. Training the new kidnapped recruits doesn't seem very important to Frank, Uncle's evil lackey, even though a few of these kids have amazing theiving skills and genius for new technology. But then Caleb figures out it's because Frank doesn't plan on keeping them around very long - or keeping them alive. Stakes are high for all of the time snatchers. If only Caleb can convince the new ones to stop having fun with the technology and use it to save their own lives. .

Time Travel: Ten Short Lessons (Pocket Einstein Series)
by Brian CleggDuring times like these, who hasn't daydreamed about traveling forward or backward in time?In Time Travel: Ten Short Lessons, popular-science master Brian Clegg gives a grand tour of the essential lessons in this game-changing area of physics, from the imagination of novelists to current research.Einstein's special theory of relativity told us that time travel to the future was possible, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backward, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with paradoxical twists in time—and could quantum physics hold the answer? Packed full of easy-to-understand diagrams and fact boxes, these ten lessons cover all the basics, as well as the latest understanding and developments, to enlighten the nonscientist.About the series: The Pocket Einstein series is a collection of essential pocket-sized guides for anyone looking to understand a little more about some of the most important and fascinating areas of science in the twenty-first century. Broken down into ten simple lessons and written by leading experts in their field, discover the ten most important takeaways from those areas of science you've always wanted to know more about.
Time Travel: A History
by James GleickFrom the acclaimed author of The Information and Chaos, here is a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself. The story begins at the turn of the previous century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book and an international sensation: The Time Machine. It was an era when a host of forces was converging to transmute the human understanding of time, some philosophical and some technological: the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. James Gleick tracks the evolution of time travel as an idea that becomes part of contemporary culture--from Marcel Proust to Doctor Who, from Jorge Luis Borges to Woody Allen. He investigates the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.(With a color frontispiece and black-and-white illustrations throughout) From the Hardcover edition.
Time Travel: A Writer's Guide to the Real Science of Plausible Time Travel
by Paul J. NahinFrom 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.
Time Travel and Warp Drives: A Scientific Guide to Shortcuts through Time and Space
by Allen Everett Thomas RomanTo see video demonstrations of key concepts from the book, please visit this website: http://www.press.uchicago.edu/sites/timewarp/ Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars? Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them! Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.
Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time
by J. Richard GottA 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

Time Traveler: In Search of Dinosaurs and Other Fossils from Montana to Mongolia
by Michael NovacekTrue stories of fossil-hunting adventures around the globe from “a world-class field scientist [and] a highly entertaining writer” (The American Scholar).Michael Novacek, a world-renowned paleontologist who has discovered important fossils on virtually every continent, is an authority on patterns of evolution and on the relationships among extinct and extant organisms. Time Traveler is his captivating account of how his boyhood enthusiasm for dinosaurs became a lifelong commitment to vanguard science. He takes us with him as he discovers fossils in his own backyard in Los Angeles, then goes looking for them in the high Andes, the black volcanic mountains of Yemen, and the incredibly rich fossil badlands of the Gobi Desert.Wherever Novacek goes, he searches for still-undiscovered evidence of what life was like on Earth millions of years ago. Along the way he has almost drowned, been stung by deadly scorpions, been held at gunpoint by a renegade army, and nearly choked in raging dust storms. Fieldwork is very demanding in a host of unusual, dramatic, sometimes hilarious ways, and Novacek writes of its alluring perils with affection and discernment. But in addition to being an enthralling adventure story, Time Traveler makes sense of many complex themes—about dinosaur evolution, continental drift, mass extinctions, new methods for understanding ancient environments, and the evolutionary secrets of DNA in fossil organisms.Includes photos and illustrations“A superb introduction to paleontology.” —Edward O. Wilson“An engaging book [that] gives us an excellent sense of the way paleontologists have arrived at their world-shaking conclusions.” —The New York Times Book Review“Novacek offers a spellbinding natural history of our planet, as well as the equally fascinating story of how he fell into the profession.” —Publishers Weekly
Time Travelers: Victorian Encounters with Time and History
by Adelene Buckland Sadiah QureshiThe Victorians, perhaps more than any Britons before them, were diggers and sifters of the past. Though they were not the first to be fascinated by history, the intensity and range of their preoccupations with the past were unprecedented and of lasting importance. The Victorians paved the way for our modern disciplines, discovered the primeval monsters we now call the dinosaurs, and built many of Britain’s most important national museums and galleries. To a large degree, they created the perceptual frameworks through which we continue to understand the past. Out of their discoveries, new histories emerged, giving rise to fresh debates, while seemingly well-known histories were thrown into confusion by novel tools and methods of scrutiny. If in the eighteenth century the study of the past had been the province of a handful of elites, new technologies and economic development in the nineteenth century meant that the past, in all its brilliant detail, was for the first time the property of the many, not the few. Time Travelers is a book about the myriad ways in which Victorians approached the past, offering a vivid picture of the Victorian world and its historical obsessions.
Time Warped: Unlocking the Mysteries of Time Perception
by Claudia HammondWe are obsessed with time. However hard we might try, it is almost impossible to spend even one day without the marker of a clock. But how much do we understand about time, and is it possible to retrain our brains and improve our relationship with it? Drawing on the latest research from the fields of psychology, neuroscience, and biology, and using original research on the way memory shapes our understanding of time, acclaimed writer and broadcaster Claudia Hammond delves into the mysteries of time perception. Along the way, she introduces us to an extraordinary array of colourful characters willing to go to great lengths in the interests of research, such as the French speleologist Michel, who spends two months in an ice cave in complete darkness. Time Warped shows us how to manage our time more efficiently, speed time up and slow it down at will, plan for the future with more accuracy, and, ultimately, use the warping of time to our own advantage.
Time Warped: Unlocking the Mysteries of Time Perception
by Claudia HammondAn award–winning BBC podcast host “has a steady touch . . . adding user-friendly charm” to “intriguing” research on the psychology of time perception (New York Times).Why does life seem to speed up as we get older? Why does the clock in your head move at a different speed from the one on the wall? Why is it almost impossible to go a whole day without checking your watch? Is it possible to retrain our brains and improve our relationship with it? In Time Warped, Claudia Hammond offers insight into how to manage our time more efficiently, how to speed time up and slow it down at will, how to plan for the future with more accuracy, and she teaches how to use the warping of time to our own benefit.“An ideal read for those looking for science-based theories of time perception without the scientific jargon. . . . Hammond demonstrates how life’s circumstances can make minutes seem an eternity and decades the blink of an eye.” —Library Journal“A well-researched meditation on how we see the future.” —Slate“This lively introduction to the psychology of time perception is an intriguing take on the fluidity of reality.” —Publishers Weekly“. . . a fascinating foray into the idea that our experience of time is actively created by our own minds and how these sensations of what neuroscientists and psychologists call “mind time” are created.” —Maria Popova, The Marginalian

Timefulness: How Thinking Like a Geologist Can Help Save the World
by Marcia BjornerudWhy an awareness of Earth’s temporal rhythms is critical to our planetary survivalFew of us have any conception of the enormous timescales in our planet’s long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. The passage of nine days, which is how long a drop of water typically stays in Earth’s atmosphere, is something we can easily grasp. But spans of hundreds of years—the time a molecule of carbon dioxide resides in the atmosphere—approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth’s deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet’s past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system—some fast, some slow—demand a poly-temporal worldview, one that Bjornerud calls “timefulness.” She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth’s history—and the magnitude of our effects on the planet.
Timekeepers: How the World Became Obsessed with Time
by Simon GarfieldBy the bestselling author of Just My Type: a &“thoroughly enjoyable and illuminating&” journey into the concept of time &“stuffed with fascinating material&” (Observer, UK).Timekeepers is a book about our obsession with time and our desire to measure it, control it, sell it, film it, perform it, immortalize it and make it meaningful. In this fascinating, anecdotal exploration, award-winning author Simon Garfield has two simple intentions: to tell some illuminating stories, and to ask whether we have all gone completely nuts. Here, Garfield explores the nature of time through stories such as: the Beatles learning to be brilliant in an hour and a half; an Englishman arriving back from Calcutta, refusing to adjust his watch; Beethoven&’s symphonic wishes being ignored; a US Senator&’s speech that goes for 25 hours; the horrors of war frozen at the click of a camera; a woman who designs a ten-hour clock and reinvents the calendar; Roger Bannister living out the same four minutes over a lifetime; and a who prince attempts to stop time in its tracks.&“Digressive, gossipy, thoughtful and thoroughly entertaining.&”—The Sunday Times, UK

Timeless Quantum Mechanics and the Early Universe (Springer Theses)
by Leonardo ChataignierThe book is based on the author's PhD thesis, which deals with the concept of time in quantum gravity and its relevance for the physics of the early Universe. It presents a consistent and complete new relational formulation of quantum gravity (more specifically, of quantum mechanics models with diffeomorphism invariance), which is applied to potentially observable cosmological effects. The work provides answers to the following questions: How can the dynamics of quantum states of matter and geometry be defined in a diffeomorphism-invariant way? What is the relevant space of physical states and which operators act on it? How are the quantum states related to probabilities in the absence of a preferred time? The answers can provide a further part of the route to constructing a fundamental theory of quantum gravity. The book is well-suited to graduate students as well as professional researchers in the fields of general relativity and gravitation, cosmology, and quantum foundations.

Despite many failures, Edison persevered. And good for that, because it would be very difficult to go through a day without using one of his life-changing inventions. In this enlightening book, Gene Barretta enters the laboratories of one of America's most important inventors.
Timeless Vision: Understanding God's Creation through the Lens of Science
by Jim JohnsonFaith and facts are reconciled in this revelatory examination of biblical and secular truths that follows the path to God through science, not around it. Always a man of science, Jim Johnson accepted Christ into his life shortly after his fiftieth birthday. This acceptance of God&’s unseeable power did not shake his belief in science—it strengthened it. Through years of research on the world&’s evolution, Johnson found that in studying every new hypothesis and theory, he believes even more in God&’s universal role.Timeless Vision: Understanding God&’s Creation through the Lens of Science bridges the gap between faith and science. Johnson examines the natural progression of Earth&’s creation alongside the seven biblical days, explains the conundrum of time, and expands upon the ever-evolving relationship humanity has with science and religion. Through analyzing scripture with detailed data and using science to bolster Christian beliefs, Johnson reveals just how rare and privileged Earth and human life truly are. It is through studying science and faith together, not apart, that we can see how God&’s plan was developed and why He did it. One is not complete without the other. Let Johnson lead you down the path less traveled—the one of science and faith—and show how God gave humanity these ways to discover Him more fully and completely.
