2014 National Book Award Finalist A Time Best YA Book of All Time (2021) Travis Coates has a good head…on someone else’s shoulders. A touching, hilarious “tour de force of imagination and empathy” (Booklist, starred review) from John Corey Whaley, author of the Printz and Morris Award–winning Where Things Come Back. Listen—Travis Coates was alive once and then he wasn’t. Now he’s alive again. Simple as that. The in between part is still a little fuzzy, but Travis can tell you that, at some point or another, his head got chopped off and shoved into a freezer in Denver, Colorado. Five years later, it was reattached to some other guy’s body, and well, here he is. Despite all logic, he’s still sixteen, but everything and everyone around him has changed. That includes his bedroom, his parents, his best friend, and his girlfriend. Or maybe she’s not his girlfriend anymore? That’s a bit fuzzy too. Looks like if the new Travis and the old Travis are ever going to find a way to exist together, there are going to be a few more scars. Oh well, you only live twice.

Twenty five years have elapsed since the original publication of Helium Cryogenics. During this time, a considerable amount of research and development involving helium fluids has been carried out culminating in several large-scale projects. Furthermore, the field has matured through these efforts so that there is now a broad engineering base to assist the development of future projects. Helium Cryogenics, 2nd edition brings these advances in helium cryogenics together in an updated form. As in the original edition, the author's approach is to survey the field of cryogenics with emphasis on helium fluids. This approach is more specialized and fundamental than that contained in other cryogenics books, which treat the associated range of cryogenic fluids. As a result, the level of treatment is more advanced and assumes a certain knowledge of fundamental engineering and physics principles, including some quantum mechanics. The goal throughout the work is to bridge the gap between the physics and engineering aspects of helium fluids to provide a source for engineers and scientists to enhance their usefulness in low-temperature systems.

Outer Cryo Worlds is a book about the fascinating world of celestial bodies with cryo, or freezing conditions. For example, with average temperatures about 200 degrees colder than Earth’s, Saturn’s moon Titan is a cryo world, one with astoundingly different sights, textures and physical forces. With such stark differences to the world, we are accustomed to, cryo worlds create a whole new universe for our imaginations, with new sightseeing adventures, sport activity potential and, who knows, maybe even extraterrestrial life. The book familiarises the reader with the concept of outer cryo worlds and their mesmerising nature. With amusing anecdotes about cryogenics and celestial bodies, it helps spark imagination and curiosity to really bring these worlds to life. Based on real facts that we know about Outer Cryo Worlds, the book takes the reader on a vivid imaginary journey of flying with tech-wings in Titan’s atmosphere or swimming in its liquid methane lakes in futuristic suits. It vividly paints the picture of what it's like to open a bottle of champagne on conquering Olympus Mons on Mars. The book also shares the author’s long-standing fascination with effects low temperatures have on life. It starts with a simple question: what happens to living organisms at low temperatures. Based on what we know about life in the deep waters of Earth, the author speculates what life would look like if it was sparked in oceans that might exist under the ice crusts of Jovian planets moons, inviting the readers on an imaginary mission of replacing tracking buoys attached to a gigantic snailfish-like creature in the abyss of Europa Ocean.
A New York Times Notable Book A New York Times bestseller, “DeLillo’s haunting new novel, Zero K—his most persuasive since his astonishing 1997 masterpiece, Underworld” (The New York Times), is a meditation on death and an embrace of life. Jeffrey Lockhart’s father, Ross, is a billionaire in his sixties, with a younger wife, Artis Martineau, whose health is failing. Ross is the primary investor in a remote and secret compound where death is exquisitely controlled and bodies are preserved until a future time when biomedical advances and new technologies can return them to a life of transcendent promise. Jeff joins Ross and Artis at the compound to say “an uncertain farewell” to her as she surrenders her body. “We are born without choosing to be. Should we have to die in the same manner? Isn’t it a human glory to refuse to accept a certain fate?” These are the questions that haunt the novel and its memorable characters, and it is Ross Lockhart, most particularly, who feels a deep need to enter another dimension and awake to a new world. For his son, this is indefensible. Jeff, the book’s narrator, is committed to living, to experiencing “the mingled astonishments of our time, here, on earth.” Don DeLillo’s “daring…provocative…exquisite” (The Washington Post) new novel weighs the darkness of the world—terrorism, floods, fires, famine, plague—against the beauty and humanity of everyday life; love, awe, “the intimate touch of earth and sun.” “One of the most mysterious, emotionally moving, and rewarding books of DeLillo’s long career” (The New York Times Book Review), Zero K is a glorious, soulful novel from one of the great writers of our time.
This book is the first in English being entirely dedicated to Miniature Joule-Thomson Cryocooling. The category of Joule-Thomson (JT) cryocoolers takes us back to the roots of cryogenics, in 1895, with figures like Linde and Hampson. The "cold finger" of these cryocoolers is compact, lacks moving parts, and sustains a large heat flux extraction at a steady temperature. Potentially, they cool down unbeatably fast. For example, cooling to below 100 K (minus 173 Celsius) might be accomplished within only a few seconds by liquefying argon. A level of about 120 K can be reached almost instantly with krypton. Indeed, the species of coolant plays a central role dictating the size, the intensity and the level of cryocooling. It is the JT effect that drives these cryocoolers and reflects the deviation of the "real" gas from the ideal gas properties. The nine chapters of the book are arranged in five parts. •The Common Principle of Cyrocoolers shared across the broad variety of cryocooler types •Theoretical Aspects: the JT effect and its inversion, cooling potential of coolants, the liquefaction process, sizing of heat exchangers, level of pressurization, discharge of pressure vessels • Practical Aspects: modes of operation (fast cooldown, continuous, multi-staging, hybrid cryocoolers), pressure sources, configuration, construction and technologies, flow adjustment, MEMS, open and closed cycle, cooldown process and similarity, transient behavior • Mixed Coolant cryocooling: theory, practice and applications • Special Topics: real gas choked flow rates, gas purity, clog formation, optimal fixed orifice, modeling, cryosurgical devices, warming by the inverse JT effect The theoretical aspects may be of interest not only to those working with cryocoolers but also for others with a general interest in "real" gas thermodynamics, such as, for example, the inversion of the JT effect in its differential and integral forms, and the exceptional behavior of the quantum gases. A detailed list of references for each chapter comprises a broad literature survey. It consists of more than 1,200 relevant publications and 450 related patents. The systematically organized content, arranged under a thorough hierarchy of headings, supported by 227 figures and 41 tables, and accompanied by various chronological notes of evolution, enables readers a friendly interaction with the book. Dr. Ben-Zion Maytal is a Senior Researcher at Rafael-Advanced Defense Systems, Ltd., and an Adjunct Senior Teaching Fellow at the Technion-Israel Institute of Technology, Haifa, Israel. Prof. John M. Pfotenhauer holds a joint appointment in the Departments of Mechanical Engineering and Engineering Physics at the University of Wisconsin - Madison.
