Book Description
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.

Book Description
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 Description
Why our cats are a danger to species diversity and human health In 1894, a lighthouse keeper named David Lyall arrived on Stephens Island off New Zealand with a cat named Tibbles. In just over a year, the Stephens Island Wren, a rare bird endemic to the island, was rendered extinct. Mounting scientific evidence confirms what many conservationists have suspected for some time—that in the United States alone, free-ranging cats are killing birds and other animals by the billions. Equally alarming are the little-known but potentially devastating public health consequences of rabies and parasitic Toxoplasma passing from cats to humans at rising rates. Cat Wars tells the story of the threats free-ranging cats pose to biodiversity and public health throughout the world, and sheds new light on the controversies surrounding the management of the explosion of these cat populations. This compelling book traces the historical and cultural ties between humans and cats from early domestication to the current boom in pet ownership, along the way accessibly explaining the science of extinction, population modeling, and feline diseases. It charts the developments that have led to our present impasse—from Stan Temple's breakthrough studies on cat predation in Wisconsin to cat-eradication programs underway in Australia today. It describes how a small but vocal minority of cat advocates has campaigned successfully for no action in much the same way that special interest groups have stymied attempts to curtail smoking and climate change. Cat Wars paints a revealing picture of a complex global problem—and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.

Book Description
When a traveller from China crash-lands on Mars, he finds himself in a country inhabited entirely by Cat People. Befriended by a local cat-man, he becomes acquainted in all aspects of cat-life: he learns to speak Felinese, masters cat-poetry, and appreciates the narcotic effects of the reverie leaf - their food staple. But curiosity turns to despair when he ventures further into the heart of the country and the culture, and realizes that he is witnessing the bleak decline of a civilization. Cat Country, Lao She's only work of science fiction, is both a dark, dystopian tale of one man's close encounter with the feline kind and a scathing indictment of a country gone awry.

Book Description
Noocee, Nuffy and Peacher Boy were happy house cats. Escaping to the outdoors to play with their forest friends in the near by woods was their most favorite thing to do. The forest animals told them many times about a far away place where only cats and dogs could go. It was told to them that a bright light would appear and the next thing you know they would be gone. The cats thought they were only teasing because they never heard a cat or dog who went missing into a bright light. They heard on TV that sometimes a dog or cat was lost only to show up months, even years later on their owner’s doorstep. The cats dismissed the story their friends told them coming back to the forest year after year to play fun games in the woods especially hide and seek. One day, while trying to find new hiding places, a bright light did appear in front of them. Peacher Boy, who was always adventurous, ran right into the light and disappeared in front of their eyes. Scared, they ran after him into the bright light too. Tumbling into the light they soon landed on what appeared to look like a leap. Where are we, how did we get here, what happened the cats were asking each other when they heard a faint Hello. Frozen in place the three knew they weren’t in their woods anymore.
