What deep-sea creature has eight arms but no feet? Which playful birds can't fly but are excellent swimmers? Children will find out in this informative coloring book featuring simple portraits of 30 different marine animals. The pictures are accompanied by easy-to-read captions that will introduce kids to a sea lion, humpback whale, penguin, great white shark, swordfish, sailfish, stingray, manatee, octopus, hermit crab, sea turtles, and other intriguing animals.

A prize-winning popular science writer uses mathematical modeling to explain the cosmosIn Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why start implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.Beginning with the Babylonian integration of mathematics into the study of astronomy and cosmology, Stewart traces the evolution of our understanding of the cosmos: How Kepler's laws of planetary motion led Newton to formulate his theory of gravity. How, two centuries later, tiny irregularities in the motion of Mars inspired Einstein to devise his general theory of relativity. How, eighty years ago, the discovery that the universe is expanding led to the development of the Big Bang theory of its origins. How single-point origin and expansion led cosmologists to theorize new components of the universe, such as inflation, dark matter, and dark energy. But does inflation explain the structure of today's universe? Does dark matter actually exist? Could a scientific revolution that will challenge the long-held scientific orthodoxy and once again transform our understanding of the universe be on the way? In an exciting and engaging style, Calculating the Cosmos is a mathematical quest through the intricate realms of astronomy and cosmology.

A god, his mother, and a Nightmare Crow. Old enemies surface once again and undead pirates roam the seas. The man he killed, Black Axe Morgan, has returned for revenge on Captain Rafe Morrow, while from the shadows the Nightmare Crow reveals his true self. The two form an alliance and bring mayhem to the seas, all to draw out Captain Morrow and his crew. Yet, this time, Rafe doesn’t face his enemies alone. Death walks the Outer Islands to save her son and the Sovereign of the Gods leads Captain Morrow past all the lies to the truth. The fate of Chaos and Harmony itself hangs in the balance of this fight. Will centuries of schemes and plans reforge the bond of the realms, or will the Seven Kingdoms and the Outer Islands fall? Can the God of Souls find his destiny before it is too late? The endgame of gods begins…

A celebrated mathematician traces the history of math through the lives and work of twenty-five pioneering mathematiciansIn Significant Figures, acclaimed mathematician Ian Stewart explores the work of 25 of history's most important mathematicians, showing how they developed on each other's work and built the mathematics we use today. Through these short biographies, we get acquainted with the history of mathematics from Archimedes to William Thurston, and learn about those too often left out of the cannon, such as Muhammad ibn Musa al-Khwarizmi, the creator of algebra; Ada Lovelace, the world's first computer programmer; and Emmy Noether, whose research on symmetry paved the way for modern physics.Tracing the evolution of mathematics over the course of two millennia, Significant Figures will educate and delight aspiring mathematicians and experts alike.

An exciting story that all young readers will love!!Get ready for a new heartwarming and exhilarating adventure from C.G. Stewart.Become one of the few humans to peak into the secret world of the animals.One little panda, who yearns for a life of adventure out with the safe confines of the zoo, gets more than he bargained for and endures a life threatening journey filled with danger, excitement and a new found unbreakable friendship.A story of friendship, love and resistance that pits two young, innocent friends against old school evil. Follow them as they use their knowledge, quick wits (and some unknown secret qualities!!) to survive unknown cities, dangerous enemies and perilous situations.

Ian Stewart's up-to-the-minute guide to the cosmos moves from the formation of the Earth and its Moon to the planets and asteroids of the solar system and from there out into the galaxy and the universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it will end. He considers parallel universes, what forms extra-terrestrial life might take, and the likelihood of Earth being hit by an asteroid.Mathematics, Professor Stewart shows, has been the driving force in astronomy and cosmology since the ancient Babylonians. He describes how Kepler's work on planetary orbits led Newton to formulate his theory of gravity, and how two centuries later irregularities in the motion of Mars inspired Einstein's theory of general relativity. In crystal-clear terms he explains the fundamentals of gravity, spacetime, relativity and quantum theory, and shows how they all relate to each other. Eighty years ago the discovery that the universe is expanding led to the Big Bang theory of its origins. This in turn led cosmologists to posit features such as dark matter and dark energy. But does dark matter exist? Could another scientific revolution be on the way to challenge current scientific orthodoxy? These are among the questions Ian Stewart raises in his quest through the realms of astronomy and cosmology.
