"Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. Geometry doesn't just measure the world-it explains it. Shape shows us how"--

Leo teaches his cat Pallas all about cubes by applying his knowledge of geometry to their Stone Age world. Funny illustrations and stories provide a humorous introduction to math concepts.

Provides a self-paced method for learning the general concepts and fundamentals of geometry, and includes multiple-choice questions at the end of each chapter and a final exam.

"Leo teaches his cat Pallas all about spheres by applying his knowledge of geometry to their Stone Age world. Entertaining illustrations and stories provide a fun introduction to math concepts, including radius, circumference, and diameter. Information boxes accompany each story to explore real applications of spheres in the natural and designed world."--

Publisher Annotation: Stunning photographs by a National Geographic photographer invite children to look around and find a world of circles, triangles, squares, and much more.

"Leo teaches his cat Pallas all about squares by applying his knowledge of geometry to their Stone Age world. Funny illustrations and stories provide a humorous introduction to math concepts, explaining how lines and angles of equal size form squares that frame, support, and enclose. Information boxes accompany each story to explore real applications of squares in the natural and designed world."--

"This book offers a multifaceted perspective on mathematics by demonstrating 99 different proofs of the same theorem. Each chapter solves an otherwise unremarkable equation in distinct historical, formal, and imaginative styles that range from Medieval, Topological, and Doggerel to Chromatic, Electrostatic, and Psychedelic. With a rare blend of humor and scholarly aplomb, Philip Ording weaves these variations into an accessible and wide-ranging narrative...

"The 2nd edition of this nontraditional, tactile introduction to hyperbolic geometry has updated chapters on the early development of geometry and connections between geometry, art, nature, and sciences, including some more recent applications of hyperbolic geometry in medicine, neuroscience, architecture, fashion design, quantum computing. Crafters who enjoyed the crocheting hyperbolic planes described in first edition ... will be delighted to find...
