If you want to know where you are, you need a good clock. The surprising connection between time and placeais explored inaTime and Navigation- The Untold Story of Getting from Here to There, the companion book to the National Air and Space Museum exhibition of the same name. Today we use smartphones and GPS, but navigating has not always been so easy. The oldest "clock" is Earth itself, and the oldest means of keeping time came from observing changes in the sky. Early mariners like the Vikings accomplished amazing feats of navigation without using clocks at all. Pioneering seafarers in the Age of Exploration used dead reckoning and celestial navigation; later innovations such as sextants and marine chronometers honed these techniques by measuring latitude and longitude. When explorers turned their sights to the skies, they built on what had been learned at sea. For example, Charles Lindbergh used a bubble sextant on his record-breaking flights. World War II led to the development of new flight technologies, notably radio navigation, since celestial navigation was not suited for all-weather military operations. These forms of navigation were extended and enhanced when explorers began guiding spacecraft into space and across the solar system. Astronauts combined celestial navigation technology with radio transmissions. The development of the atomic clock revolutionized space flight because it could measure billionths of a second, thereby allowing mission teams to navigate more accurately. Scientists and engineers applied these technologies to navigation on earth to develop space-based time and navigation services such as GPS that is used every day by people from all walks of life. While the history of navigation is one of constant change and innovation, it is also one of remarkable continuity. Time and Navigation tells the story of navigation to help us understand where we have been and how we got there so that we can understand where we are going.
Thoroughly rewritten for today's web environment, this bestselling book offers a fresh look at a fundamental topic of web site development: navigation design. Amid all the changes to the Web in the past decade, and all the hype about Web 2.0 and various "rich" interactive technologies, the basic problems of creating a good web navigation system remain. Designing Web Navigation demonstrates that good navigation is not about technology-it's about the ways people find information, and how you guide them. Ideal for beginning to intermediate web designers, managers, other non-designers, and web development pros looking for another perspective, Designing Web Navigation offers basic design principles, development techniques and practical advice, with real-world examples and essential concepts seamlessly folded in. How does your web site serve your business objectives? How does it meet a user's needs? You'll learn that navigation design touches most other aspects of web site development. This book: Provides the foundations of web navigation and offers a framework for navigation design Paints a broad picture of web navigation and basic human information behavior Demonstrates how navigation reflects brand and affects site credibility Helps you understand the problem you're trying to solve before you set out to design Thoroughly reviews the mechanisms and different types of navigation Explores "information scent" and "information shape" Explains "persuasive" architecture and other design concepts Covers special contexts, such as navigation design for web applications Includes an entire chapter on tagging While Designing Web Navigation focuses on creating navigation systems for large, information-rich sites serving a business purpose, the principles and techniques in the book also apply to small sites. Well researched and cited, this book serves as an excellent reference on the topic, as well as a superb teaching guide. Each chapter ends with suggested reading and a set of questions that offer exercises for experiencing the concepts in action.
Navigation in the Mountains - The Definitive Guide for Hill Walkers, Mountaineers & Leaders is the official navigation book for all Mountain Training schemes. Packed with essential information and techniques, this handbook is split into sections including: all aspects of mountain navigation; the additional techniques required in winter; adaptations in navigation techniques for use overseas; the use of GPS; digital mapping; and the teaching of navigation. This book is the reference tool for all walkers who wish to maintain or improve their navigation techniques as well as containing specific ideas for anyone wanting to help teach and lead others. Its functional design with easy reference colour coded pages, striking illustrations that complement the text and inspiring photographs make this book an indispensable guide. It is the fourth in a series of manuals and has been written and compiled by Carlo Forte, the Chief Instructor at the National Mountain Centre, Plas y Brenin, and it is published by Mountain Training UK.
"NOLS Wilderness Navigation" gives you the skills you need to confidently find your way on and off the trail. Whether you are learning to use a map and compass or exploring the latest technology, this eay-to-follow guide is packed with essential information.
Certain technologies bring out everyone's hidden geek, and iPhone did the moment it was released. Even though Apple created iPhone as a closed device, tens of thousands of developers bought them with the express purpose of designing and running third-party software. In this clear and concise book, veteran hacker Jonathan Zdziarski -- one of the original hackers of the iPhone -- explains the iPhone's native environment and how you can build software for this device using its Objective-C, C, and C++ development frameworks. iPhone Open Application Development walks you through the iPhone's native development environment, offers an overview of the Objective-C language you'll use with it, and supplies background for the iPhone operating system. You also get detailed recipes and working examples for everyone's favorite iPhone features -- graphics and audio programming, interfaces for adding multitouch functionality to games, the use of hardware sensors, and the device's vast user interface kit. This book explains: How to access the iPhone's underlying operating system The makeup of an iPhone application How to get the open source tool chain running on your desktop The iPhone's core user interface framework, which is heavily tied to major application-level functions Using the many touted iPhone features such as multitouch, hardware sensors, and gestures Intercepting and handling event notifications for many iPhone-related events Raw video surfaces and 3D transformations that take you deeper into advanced graphics on the iPhone How to record and play simple sounds and intercept sound events Advanced digital audio output using Apple's new Audio Toolbox framework Advanced user interface components such as section lists, keyboards, and image manipulation The Appendix includes a compendium of miscellaneous code examples for cool application features, such as using the camera and creating a CoverFlow®-like album browser. This book is a true hacker's book, designed for the millions of users who have run third party applications on their iPhone, but its concepts and code examples have shown to be remarkably similar to Apple's official SDK, making this book a valuable resource for both camps. Any programmer can use this book to write applications with the same spectacular effects that made the device an immediate hit, and impress users just as much as the official iPhone software does. That programmer can easily be you.
