Available in PDF, EPUB and Kindle. Book excerpt: How to use physical reasoning to solve surprising paradoxes Ever wonder why cats land on their feet? Or what holds a spinning top upright? Or whether it is possible to feel the Earth's rotation in an airplane? Why Cats Land on Their Feet is a compendium of paradoxes and puzzles that readers can solve using their own physical intuition. And the surprising answers to virtually all of these astonishing paradoxes can be arrived at with no formal knowledge of physics. Mark Levi introduces each physical problem, sometimes gives a hint or two, and then fully explains the solution. Here readers can test their critical-thinking skills against a whole assortment of puzzles and paradoxes involving floating and diving, sailing and gliding, gymnastics, bike riding, outer space, throwing a ball from a moving car, centrifugal force, gyroscopic motion, and, of course, falling cats. Want to figure out how to open a wine bottle with a book? Or how to compute the square root of a number using a tennis shoe and a watch? Why Cats Land on Their Feet shows you how, and all that's required is a familiarity with basic high-school mathematics. This lively collection also features an appendix that explains all physical concepts used in the book, from Newton's laws to the fundamental theorem of calculus.

Available in PDF, EPUB and Kindle. Book excerpt: How do cats land on their feet? Discover how this question stumped brilliant minds and how its answer helped solve other seemingly impossible puzzles The question of how falling cats land on their feet has long intrigued humans. In this playful and eye-opening history, physicist and cat parent Gregory Gbur explores how attempts to understand the cat-righting reflex have provided crucial insights into puzzles in mathematics, geophysics, neuroscience, and human space exploration. The result is an engaging tumble through physics, physiology, photography, and robotics to uncover, through scientific debate, the secret of the acrobatic performance known as cat-turning, the cat flip, and the cat twist. Readers learn the solution but also discover that the finer details still inspire heated arguments. As with other cat behavior, the more we investigate, the more surprises we discover.

Book excerpt: Why spend one life worrying . . . when you could spend nine lives napping? Take it from artist Jamie Shelman's wry and furry felines: Cats work reasonable hours (zero), love wisely (from a distance), and live boldly (until someone starts vacuuming). Don't go without these 100 sage lessons: Be especially attentive to the one person who doesn’t like you. Get away with murder by looking cute. Ignore anyone who doesn't worship you. Be pleased with your achievements, however small. The best solution to a problem is a nap. Live better—live like your cat!
Book Synopsis Rotation, Reflection, and Frame Changes by : Rebecca M Brannon
Download or read book Rotation, Reflection, and Frame Changes written by Rebecca M Brannon and published by . This book was released on 2018-05-23 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthogonal tensors are mainly used to describe rotation. They play a central role in robotics, rigid-body kinematics, and all other branches of engineering mechanics, especially for modelling elastic and inelastic behavior of materials. Whilst vast literature is available for common rotation-related tasks, such as coordinate changes, most reference books tend to cover one or two methods for handling rotations, while often neglecting relatively obscure rotation-related tasks, such as statistical sampling of rotation for multiscale constitutive modeling. Further specialized rotation-related research can be found only in disparate journal articles. Of the few books that do exist, most are aimed at mathematicians, leaving a need for this self-contained engineering focused review that covers both elementary and advanced concepts. Rotation, Reflection, and Frame Changes presents a refreshingly broad range of rotation-related research that is routinely needed in modern engineering practice. By including theorems and physical insight acquired over her 30+ career as both as laboratory and university researcher, Rebecca Brannon has created a truly practical and accessible guide for engineers and scientists in engineering mechanics. Although the book assumes familiarity with multivariate calculus, linear algebra, and elementary tensor analysis, tutorials and provided computer source code guide the reader through more advanced topics.
Book Synopsis Geometry, Mechanics, and Control in Action for the Falling Cat by : Toshihiro Iwai
Download or read book Geometry, Mechanics, and Control in Action for the Falling Cat written by Toshihiro Iwai and published by Springer Nature. This book was released on 2021-04-23 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The falling cat is an interesting theme to pursue, in which geometry, mechanics, and control are in action together. As is well known, cats can almost always land on their feet when tossed into the air in an upside-down attitude. If cats are not given a non-vanishing angular momentum at an initial instant, they cannot rotate during their motion, and the motion they can make in the air is vibration only. However, cats accomplish a half turn without rotation when landing on their feet. In order to solve this apparent mystery, one needs to thoroughly understand rotations and vibrations. The connection theory in differential geometry can provide rigorous definitions of rotation and vibration for many-body systems. Deformable bodies of cats are not easy to treat mechanically. A feasible way to approach the question of the falling cat is to start with many-body systems and then proceed to rigid bodies and, further, to jointed rigid bodies, which can approximate the body of a cat. In this book, the connection theory is applied first to a many-body system to show that vibrational motions of the many-body system can result in rotations without performing rotational motions and then to the cat model consisting of jointed rigid bodies. On the basis of this geometric setting, mechanics of many-body systems and of jointed rigid bodies must be set up. In order to take into account the fact that cats can deform their bodies, three torque inputs which may give a twist to the cat model are applied as control inputs under the condition of the vanishing angular momentum. Then, a control is designed according to the port-controlled Hamiltonian method for the model cat to perform a half turn and to halt the motion upon landing. The book also gives a brief review of control systems through simple examples to explain the role of control inputs.

Book Synopsis Wild Cats of the World by : Mel Sunquist
Download or read book Wild Cats of the World written by Mel Sunquist and published by University of Chicago Press. This book was released on 2017-05-15 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Did you know that European royalty once used cheetahs to hunt deer, or that caracals can capture birds by leaping six and a half feet straight up into the air from a standing start? Have you ever wondered whether domestic cats really do land on their feet when they fall, or how Canada lynx can stalk their prey in the winter without falling through the deep snow? Wild Cats of the World is a treasure trove of answers to questions like these, and many others, for anyone who's interested in learning more about the world's felids, including the ones with whom we share our homes. Mel and Fiona Sunquist have spent more than a decade gathering information about cats from every available source, many of them quite difficult to find, including scientific papers, descriptions of hunts, archeological findings, observations by naturalists and travelers, reports from government agencies, and newsletters from a wide variety of organizations. Weaving information from these sources together with their own experiences observing wild cats around the world, the Sunquists have created the most comprehensive reference on felids available. Each of their accounts of the 36 species of cat contains a description of the cat, including human interactions with it, as well as detailed data on its distribution, ecology and behavior, status in the wild, and efforts to conserve it. Numerous photographs, including more than 40 in full color, illustrate these accounts. Ranging from the two-pound black-footed cat to the five-hundred-pound tiger, and from the African serval with its satellite-dish ears to the web-footed fishing cat of Asia, Wild Cats of the World will fascinate and educate felid fans of any stripe (or spot).

This engagingly illustrated book takes the same cat's-eye view of the world that infuses the Discovery Channel television series Wild Discovery. It emphasizes the untamed roots of almost every aspect of a domesticated cat's conduct: the crouch-and-pounce string-chase games that mirror stalking prey in the wild, the furniture-scratching preoccupation that echoes the territorial scent deposits a wild cat claws onto trees. Written in an accessible, authoritative style,Wild Discovery Guide to Your Catgenerously mixes the fundamentals of basic care with compelling explorations into cats' physical and psychological traits. Included in this comprehensive primer are detailed insights into all aspects of cat design, from the intricate structure of the feline form to the cat's heightened senses and remarkable agility. The guide explores why cats do the things they do--addressing such issues as grooming, sleep patterns, marking and defending territory, cat language, and learning and intelligence. In addition to probing the tiger within,Wild Discovery Guide to Your Catoffers a host of practical tips on choosing a cat to suit your lifestyle, providing responsible care, cat-proofing your home, and ensuring a smooth transition during the first days at home. Once the cat is a member of the family, the book explains how to bond and play with your new pet, and even how to train and travel with it. Everything you need to know to keep your cat healthy and happy is covered, including the latest information on feeding and nutrition, litter boxes, cleaning and grooming, common health problems, fighting fleas, pregnancy and birth, caring for an aging cat, vet visits, and emergency care. A breed breviary rounds out the book, with the spotlight on the top cat breeds as well as other common feline pedigrees. This section also presents information on body type, common colors, coat type, grooming requirements, and temperament. An informative cat owner's resource guide follows. Accompanied by more than 225 full-color illustrations and photographs showing the similarities between domestic and wild cats, this is an entertaining and insightful approach to feline behavior, pet care, and appreciation for first-time cat owners and veteran cat lovers alike. Lush, lovely, informative and practical, Wild Discovery Guide to Your Cat is a feast for both the eye and the mind...a good introduction to cat care and behavior for novices and also serves as an interesting read for long-time cat owners...There's something for everyone in this book...one of the most educational books to come along in a long time.--Cats, April 2000
Download or read book The Rock Eaters written by Brenda Peynado and published by Penguin. This book was released on 2021-05-11 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: An NPR Best Book of 2021 NYPL 10 Best Books for Adults, 2021 A story collection, in the vein of Carmen Maria Machado, Kelly Link, and Nana Kwame Adjei-Brenyah, spanning worlds and dimensions, using strange and speculative elements to tackle issues ranging from class differences to immigration to first-generation experiences to xenophobia What does it mean to be other? What does it mean to love in a world determined to keep us apart? These questions murmur in the heart of each of Brenda Peynado’s strange and singular stories. Threaded with magic, transcending time and place, these stories explore what it means to cross borders and break down walls, personally and politically. In one story, suburban families perform oblations to cattlelike angels who live on their roofs, believing that their “thoughts and prayers” will protect them from the world’s violence. In another, inhabitants of an unnamed dictatorship slowly lose their own agency as pieces of their bodies go missing and, with them, the essential rights that those appendages serve. “The Great Escape” tells of an old woman who hides away in her apartment, reliving the past among beautiful objects she’s hoarded, refusing all visitors, until she disappears completely. In the title story, children begin to levitate, flying away from their parents and their home country, leading them to eat rocks in order to stay grounded. With elements of science fiction and fantasy, fabulism and magical realism, Brenda Peynado uses her stories to reflect our flawed world, and the incredible, terrifying, and marvelous nature of humanity.

Book Synopsis The Cat's Table by : Michael Ondaatje
Download or read book The Cat's Table written by Michael Ondaatje and published by Vintage Canada. This book was released on 2012-06-12 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Michael Ondaatje: an electrifying novel, by turns thrilling and deeply moving—one of his most vividly rendered and compelling works of fiction to date. In the early 1950s, an eleven-year-old boy boards a huge liner bound for England. At mealtimes, he is placed at the lowly "Cat's Table" with an eccentric and unforgettable group of grownups and two other boys. As the ship makes its way across the Indian Ocean, through the Suez Canal, into the Mediterranean, the boys find themselves immersed in the worlds and stories of the adults around them. At night they spy on a shackled prisoner—his crime and fate a galvanizing mystery that will haunt them forever. Looking back from deep within adulthood, and gradually moving back and forth from the decks and holds of the ship to the years that follow the narrator unfolds a spellbinding and layered tale about the magical, often forbidden discoveries of childhood and the burdens of earned understanding, about a life-long journey that began unexpectedly with a sea voyage.

Available in PDF, EPUB and Kindle. Book excerpt: "Fun, fanciful, and even informative." —People The first comprehensive history of felines—from the laps of pagan gods to present-day status as meme stars—as revealed by a very learned tabby with a knack for hunting down facts Since the dawn of civilization, felines have prowled alongside mankind as they expanded their territory and spread the myth of human greatness. And today, cats are peddled on social media as silly creatures here to amuse humans with their antics. But this is an absurd, self-centered fantasy. The true history of felines is one of heroism, love, tragedy, sacrifice, and gravitas. Not entirely convinced? Well, get ready, because Baba the Cat is here to set the record straight. Spanning almost every continent and thousands—yes, thousands—of years, Baba’s complex story of feline survival presents readers with a diverse cast of cats long forgotten: from her prehistoric feline ancestors and the ancient Egyptian cat goddess Bastet to the daring mariners at the height of oceanic discovery, key intellectuals in the Enlightenment period, revered heroes from World Wars I and II, and the infamous American tabbies. Baba, a talented model in addition to a scholar, goes beyond surface-level scratches, pairing her freshly unearthed research with a series of stunning costume portraits to bring history to life. A paws-on journey through the feline hall of fame, with in-depth research and four-legged testaments that will make you rethink who defines history, A Cat’s Tale is a one-of-a-kind chronicle that introduces readers to the illustrious ancestors of their closest companions and shows, once and for all, that cats know exactly what they’re doing.
