When the party was over, everyone left, and the tortoise has no means of going home. The tortoise jumped from the sky and landed on hard rocks on the earth and shattered his shell. He became so sick and spent so many months behind the rocks. Although he got better, his shell became cracked and patchy. This is why the tortoises shell is patchy.
An African folklore about the story of the greedy Tortoise/ Turtle. Before now the Tortoise has always had a very beautiful and smooth shell. Discover through this African folklore, how the Tortoise cracked his shell and ever since it's has remained cracked.
This is a story of a tortoise that captivated the animal world with the beauty of his shell, which seemed to illuminate its path with colors of the rainbow. This story takes place in the animal world, where a long-forgotten language was spoken. You will be spellbound by the tortoises demise when his shell ended up with scars and lost its luminous beauty.
The classic textbook on comparative biomechanics—revised and expanded Why do you switch from walking to running at a specific speed? Why do tall trees rarely blow over in high winds? And why does a spore ejected into air at seventy miles per hour travel only a fraction of an inch? Comparative Biomechanics is the first and only textbook that takes a comprehensive look at the mechanical aspects of life—covering animals and plants, structure and movement, and solids and fluids. An ideal entry point into the ways living creatures interact with their immediate physical world, this revised and updated edition examines how the forms and activities of animals and plants reflect the materials available to nature, considers rules for fluid flow and structural design, and explores how organisms contend with environmental forces. Drawing on physics and mechanical engineering, Steven Vogel looks at how animals swim and fly, modes of terrestrial locomotion, organism responses to winds and water currents, circulatory and suspension-feeding systems, and the relationship between size and mechanical design. He also investigates links between the properties of biological materials—such as spider silk, jellyfish jelly, and muscle—and their structural and functional roles. Early chapters and appendices introduce relevant physical variables for quantification, and problem sets are provided at the end of each chapter. Comparative Biomechanics is useful for physical scientists and engineers seeking a guide to state-of-the-art biomechanics. For a wider audience, the textbook establishes the basic biological context for applied areas—including ergonomics, orthopedics, mechanical prosthetics, kinesiology, sports medicine, and biomimetics—and provides materials for exhibit designers at science museums. Problem sets at the ends of chapters Appendices cover basic background information Updated and expanded documentation and materials Revised figures and text Increased coverage of friction, viscoelastic materials, surface tension, diverse modes of locomotion, and biomimetics
A representative collection of eighty-one myths and folktales chosen from the oral tradition of the peoples of Africa south of the Sahara. Originally published in 1964. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Rabbit has lots of carrots and he attempts take them with him when he moves in with friends--until he realizes that the best thing to do is share his carrots with them.
"A jaw-dropping collection....Beautiful, vibrant, and electrifying, this has the makings of a modern classic." —Publishers Weekly (starred review), and a Publishers Weekly Top Ten Spring 2024 Roundup pick "For fans of Margaret Atwood’s dystopian works and P. Djèlí Clark’s speculative fiction, Convergence Problems provides an Afrocentric sf narrative that is sure to captivate." — Raychel Bennet, Booklist (starred review) "Written with an emotional economy few storytellers can master....A fascinating and riveting exploration of what the future may hold—for better or worse." —Kirkus From the Hugo, Nebula, Locus and Nommo award nominated author of Shigidi and The Brass Head Of Obalufon comes a stunning new collection of stories that investigate the rapidly changing role of technology and belief in our lives as we search for meaning, for knowledge, for justice; constantly converging on our future selves. In “An Arc of Electric Skin,” a roadside mechanic seeking justice volunteers to undergo a procedure that will increase the electrical conductivity of his skin by orders of magnitude. In “Blowout,” a woman races against time and a previously undocumented geological phenomenon to save her brother on the surface of Mars. In “Ganger,” a young woman trapped in a city run by machines must transfer her consciousness into an artificial body and find a way to give her life purpose. In “Debut,” Nairobi-based technical support engineer tries to understand what is happening when an AI art system begins malfunctioning in ways that could change the world. The sixteen stories of Convergence Problems, which include work published for the first time in this collection, rare stories, and recently acclaimed work, showcase Talabi at his creative best: playful and profound, exciting and experimental, always interesting.
