Fun pictograms and infographics about space make learning about math topics such as angles, decimals, and probability easy and fun. In this book, readers are in control of a space mission through the Solar System and use their mathematical skills to navigate past comets, dodge asteroids, and land on the surface of Mars! Math puzzles and exercises help children build confidence in their math skills.

In a brilliant flash about fourteen billion years ago, time and matter were born in a single instant of creation. An immensely hot and dense universe began its rapid expansion everywhere, creating space where there was no space and time where there was no time. In the intense fire just after the beginning, the lightest elements were forged, later to form primordial clouds that eventually evolved into galaxies, stars, and planets. This evolution is the story told in this fascinating book. Interwoven with the storyline are short pieces on the pioneering men and women who revealed those wonders to us./a

Specialized collections for tweens, or middle schoolers, are relatively new and becoming increasingly popular. This Practical Guide gives librarians everything they need to create such a collection. Beginning with a brief description of the early adolescent brain and developmental stages, and a history of youth and teen services in libraries, Creating a Tween Collection provides a solid foundation on which librarians can build support for such a collection. In addition, librarians will be given specific criteria for what constitutes “tween literature,” guidelines for forming parameters that will work for their community, and suggestions for using reviews and other sources in selecting appropriate materials and dealing with controversial titles. Finally, readers will learn how to re-allocate spaces and budgets, and how to market their new collection to patrons. This is a must-read for librarians who are looking to build a middle school collection in order to better serve their patrons. This book: - Provides rationale about the importance of a specialized Tween Collection. - Gives specific examples for both fiction and nonfiction books, databases and websites. - Provides guidance for creating diverse collections and tips for dealing with possible challenges. - Includes numerous case studies and booklists

Mathematics is the language of physics, and over time physicists have developed their own dialect. The main purpose of this book is to bridge this language barrier, and introduce the readers to the beauty of mathematical physics. It shows how to combine the strengths of both approaches: physicists often arrive at interesting conjectures based on good intuition, which can serve as the starting point of interesting mathematics. Conversely, mathematicians can more easily see commonalities between very different fields (such as quantum mechanics and electromagnetism), and employ more advanced tools.Rather than focusing on a particular topic, the book showcases conceptual and mathematical commonalities across different physical theories. It translates physical problems to concrete mathematical questions, shows how to answer them and explains how to interpret the answers physically. For example, if two Hamiltonians are close, why are their dynamics similar?The book alternates between mathematics- and physics-centric chapters, and includes plenty of concrete examples from physics as well as 76 exercises with solutions. It exploits that readers from either end are familiar with some of the material already. The mathematics-centric chapters provide the necessary background to make physical concepts mathematically precise and establish basic facts. And each physics-centric chapter introduces physical theories in a way that is more friendly to mathematicians.As the book progresses, advanced material is sprinkled in to showcase how mathematics and physics augment one another. Some of these examples are based on recent publications and include material which has not been covered in other textbooks. This is to keep it interesting for the readers.

This primer brilliantly exposes concepts related to special and general relativity for the absolute beginner. It can be used either as an introduction to the subject at a high school level or as a useful compass for undergraduates who want to move the first steps towards Einstein's theories. The book is enhanced throughout with many useful exercises and beautiful illustrations to aid understanding. The topics covered include: Lorentz transformations, length contraction and time dilation, the twin paradox (and other paradoxes), Minkowski spacetime, the Einstein equivalence principle, curvature of space and spacetime, geodesics, parallel transport, Einstein’s equations of general relativity, black holes, wormholes, cosmology, gravitational waves, time machines, and much more.
