Imaginación con René Descartes

Kids often play with magnets, yet they don't learn how these playthings work for many years. Practical knowledge from their play can help them learn more about magnetism, and so can this book. Specially written for those with reading challenges or readers looking for a review, the main text covers important vocabulary, magnetic fields, and a discussion of why metals and magnets come together. Diagrams and succinct fact boxes offer additional ways to learn each concept and explain some ideas in greater detail.

Readers may never expect that they might free fall to Earth, but if they have ever dived into a pool, that's exactly what they've done. This book shows readers how Newton's three laws of motion affect divers, skydivers, and mountain climbers' movements. Readers discover who uses gravity, and who works against it, and all other forces that contribute to a successful dive or climb. After reading this book, readers can decide if they will ever be interested in engaging in one of these extreme sports.

Las franjas y las telas listadas fueron durante mucho tiempo en occidente marcas de exclusión e infamia. Las llevaron juglares, músicos, bufones, verdugos, condenados, herejes, judíos, musulmanes, así como el Diablo y sus criaturas en la iconografía. Pero durante la época románica vieron la luz otras rayas, éstas positivas, relacionadas con la idea de libertad, juventud, placer y progreso. Michel Pastourau nos explica ese cambio y el valor que nuestra sociedad le da al tejido listado.
