If you want to know where you are, you need a good clock. The surprising connection between time and place is explored in Time 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.

Описание: This book is about the how of project management and about how you as a project manager can use a proactive attitude to stay in control, even during difficult situations. It shows you how to become an influencer of the path to the end result, of your environment, of your team and of your effectiveness.Today`s project managers have to meet high expectations. Challenging goals, a strong focus on cost management and lead times, serving the interests of different stakeholders and many dependencies between subprojects make project management an increasingly complex affair - especially in an environment where change and uncertainty have become the new norm. In addition, the creative abilities of knowledge workers have to be optimally utilised, which requires less hierarchical organisational structures and more multidisciplinary collaboration. Having the right project management skills is therefore essential at virtually every level of an organisation.As a result of these challenges, there is a growing demand for comprehensive methods and the popularity of Agile is on the rise. On the other hand, the increased complexity also results in a need for simplicity. That is what this book is about: going back to the basics, being able to combine useful elements from different methods and focusing on the most important aspect of all: the person behind the project manager!This book contains a wealth of practical descriptions with useful examples and anecdotes. Readers are constantly stimulated to internalise the essence and put it into practice in a manner that suits their own style and personality. That is the only way to keep at it, be successful and make others believe in you!The book consists of three parts. Part 1 (chapters 1 to 4) describes how to set up and manage a project. The focus is on the basic principles, the essence of taking control, creating structure and using Agile behavior. Part 2 (chapters 5 and 6) explains how to draw up a plan and schedule in small steps, which results in improved completeness, coordination and support. Finally, part 3 (chapters 7 to 10) covers how to manage the project execution: how to realize the path to the final goal with a strict PDCA rhythm, how to evaluate the quality of interim results and how to keep your team and environment motivated.
