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.

Skid doesn’t believe in ghosts or time travel or any of that nonsense. A circus runaway-turned-bouncer, she believes in hard work, self-defense, and good strong coffee. Then one day an annoying theoretical physicist named Dave pops into the seat next to her at her least favorite Kansas City bar and disappears into thin air when she punches him (he totally deserved it). Now, street names are changing, Skid’s favorite muffins are swapping frosting flavors, Dave keeps reappearing in odd places like the old Sanderson murder house—and that’s only the start of her problems. Something has gone wrong. Terribly wrong. Absolutely &#*$&ed up. Someone has the nastiest versions of every conceivable reality at their fingertips, and they're not afraid to smash them together. With the help of a smooth-talking haunted house owner and a linebacker-sized Dungeons and Dragons-loving baker, Skid and Dave set out to save the world from whatever scientific experiment has sent them all dimension-hopping against their will. It probably means the world is screwed.

The Time Machine by H. G. Wells is a science fiction classic, which lends itself well to visualization. This version, illustrated by Yoann Laurent-Rouault, an illustrator master who graduated from the Beaux-Arts, and published in the international literary collection Memoria Books, is a reference on the time travel theme. Wells transports us in the year 802 701, in a society made up of the “Elois”, who live peacefully in a kind of big Garden of Eden, eating fruits and sleeping high up, while underground lives another species, also descending from men, the “Morlocks”, who do not stand the light anymore, living in the dark for too long now. At night, they return to the surface, going back up by the wells, in order to kidnap some Elois that they eat ; these last became livestock unknowingly. In The Time Machine, made into a movie several times, the last of them in 2002 by Simon Wells, the great-grandson of H. G. Wells, time is both a pretext to move the class struggle and warn... and also, in a way, a full character, who fascinates, arbitrates, transcends... The illustrations come to reinforce the time travel and provide a new experience to the reader.

"Beautifully written, eloquently reasoned…Mr. Buonomano takes us off and running on an edifying scientific journey." —Carol Tavris, Wall Street Journal In Your Brain Is a Time Machine, leading neuroscientist Dean Buonomano embarks on an "immensely engaging" exploration of how time works inside the brain (Barbara Kiser, Nature). The human brain, he argues, is a complex system that not only tells time, but creates it; it constructs our sense of chronological movement and enables "mental time travel"—simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. This virtuosic work of popular science will lead you to a revelation as strange as it is true: your brain is, at its core, a time machine.

The race to build the first time machine.

The Paper Time Machine is a book that will change the way you think about the past.It contains 130 historical black-and-white photographs, reconstructed in colour and introduced by Wolfgang Wild – creator and curator of the Retronaut website. The site has become a global phenomenon, collecting images that collapse the distance between the past and present and tear a hole in our map of time. The Paper Time Machine goes even further. Early photographic technology lacked a crucial ingredient – colour. As early as the invention of the medium, skilled artisans applied colour to photographs by hand, attempting to convey the vibrancy and immediacy of life in vivid detail. In most cases this was crude and unconvincing. Until now. The time-bending images in The Paper Time Machine have been painstakingly restored and rendered in full and accurate colour by Jordan Lloyd of Dynamichrome, a company that has taken the craft of colour reconstruction to a new level. Each element of every photograph has been researched and colour-checked for historical authenticity. Behold American child labourers from the early twentieth century, alongside the construction of the Statue of Liberty. Marvel at crisp photographs from the Crimean War in 1855, balanced with never-before-seen pictures from the Walt Disney archive. As the layers of colour build up, the effect is disorientingly real and the decades and centuries fall away. It is as though we are standing at the original photographer’s elbow. This is a landmark photographic book – a collection of historical ‘remixes’ that exist alongside the original photographs but draw out qualities, textures and details that have hitherto remained hidden. Let The Paper Time Machine transport you. It is as close to time travel as we are ever likely to get.

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
