An ideal introduction to astronomy and astro navigation. 178 letter size pages packed with full colour illustrations, detailed diagrams and clear explanations. This book focuses on those aspects of astronomy that are essential for a complete understanding of astro navigation - a must for sailors, navigators, nautical colleges and navigation tutors. Teachers and students of many other subjects including geography and mathematics will also find this book interesting, entertaining and very informative. The only book of its kind! The final book of the 'Astro Navigation Demystified' trilogy, Author's preface: Astronomy is a vast and complex subject and when I was taught astro navigation, I often wished my tutor would 'cut to the chase' and focus on only those aspects of astronomy that were relevant. When I taught navigation myself, I searched high and low for an astronomy book that would allow me to pick out just those topics that I needed to teach my students but I was never able to find one. For many years, I meant to write such a book myself to help other astro navigation tutors and students and now, at last, I have found time to do so.

If you want a book that will not only help you to pass exams but also teach you to navigate and to understand what you are doing, then you have come to the right place. This unique course comprehensively covers all elements of the examination syllabi of the main sailing associations. The traditional 'formula method' of celestial navigation which involves the use of trigonometry to calculate a vessel's position is comprehensively taught in this book. With this method, we make accurate calculations using data taken directly from the DR position and so avoid the inaccuracies of sight reduction methods that involve interpolation from tables using data based on an 'assumed position' which is usually some distance from the DR position. Although the prime aim of the course is to teach the practical skills of celestial navigation, it is emphasised that without knowledge, skill is nothing. At the same time, it is recognized that students quickly lose interest if they are expected to plough through reams of theory before they can get down to the business of learning the skills. With this in mind, this course has been uniquely designed to teach the important skills from the outset while 'tying-in' the relevant theory as progress is made. There are numerous examples and test exercises that enhance the learning process and help to embed the knowledge and skills needed to practice the art of celestial navigation.

Applying Mathematics to Astro Navigation. This addition to the 'Astro Navigation Demystified' series focuses on the mathematical principles upon which astro / celestial navigation is based and it will appeal to anyone with an interest in these subjects whether they be navigators or mathematicians. A must for navigation course tutors and mathematics teachers.Few navigation books describe techniques that involve first principles; instead they mostly describe methods which rely upon the use of tables of computed data and rote-learned procedures. There is obviously very little educational value in such techniques; far better that students of the subject should be helped to discover and apply the underlying principles for themselves. Accordingly, the approach adopted in this book involves putting the student in the place of a navigator who has no automated navigation equipment, nautical almanac, chronometer or 'Sat. Nav.' and who must therefore discover a means of navigating without them. To this end, readers are guided through a method of calculating a position on the earth's surface by the application of spherical trigonometry without reliance upon equipment other than an angle measuring device such as a simple clinometer.Section two of the book, which is very popular with teachers and college lecturers, contains activities that are designed to provide opportunities to consolidate the knowledge acquired and provide ideal starting points for 'open-ended' projects. They are suitable for people with a wide range of interests from seafarers and sailing enthusiasts to students of mathematics and nautical studies. Note. The terms celestial navigation and astro navigation are generally regarded as synonymous.Other books in the Astro Navigation Demystified Series: Astro Navigation Demystified. The ultimate book of the series; it is a complete course in astro / celestial navigation. This unique self-teach course comprehensively covers all relevant elements of the examination syllabuses of the main sailing associations. Part one ranges from simple explanations of the basic principles through to detailed expositions of the important aspects of the subject. Part two provides a comprehensive coverage of the use of rapid sight reduction techniques for position fixing. Celestial Navigation. The Ultimate CourseThe traditional method of celestial navigation involving the use of spherical trigonometry to calculate a vessel's position is comprehensively taught in this book. At first sight, the term 'spherical trigonometry' might seem quite daunting but with the knowledge of just two formulas and with a little practice of the methods explained in this book, it will be found to be quick and easy to apply as well as very accurate. With this method, we make accurate calculations using data taken directly from a vessel's DR position and so avoid the inaccuracies of sight reduction methods that involve interpolation from tables using data based on an 'assumed position'. Astronomy For Astro Navigation. This book focuses on those aspects of astronomy that are essential for a complete understanding of astro navigation - a must for sailors, navigators, nautical colleges and navigation tutors. Teachers and students of many other subjects including geography and mathematics will also find this book interesting, entertaining and very informative. The only book of its kind - no other book focuses on only those aspects of astronomy that are relevant to astro navigation. An ideal introduction to both astronomy and astro navigation containing 178 letter size pages packed with illustrations, detailed diagrams and clear explanations."Know the stars and you will always have a compass" (The Revenant) The Astro Navigation Demystified website provides a free resource for all those interested in the subject of astro navigation (or celestial navigation as it is also known): www.astronavigationdemystified.com

If you are looking for something to enable you to rote-learn only what you need to pass an exam without real understanding, then sorry, this is not the book for you. If however, you want a book that will not only help you to pass exams but also teach you to navigate and to understand what you are doing, then you have come to the right place. This unique self-teach course comprehensively covers all elements of the examination syllabuses of the main sailing associations. Traditional methods of celestial navigation are taught in a way that is easier, faster and more accurate than other methods and does not rely on vast tables of data other than the Nautical Almanac.Although the prime aim of the course is to teach the practical skills of celestial navigation, it is emphasised that without knowledge, skill is nothing. At the same time, it is recognised that students quickly lose interest if they are expected to plough through reams of theory before they can get down to the business of learning the skills. With this in mind, this course has been uniquely designed to teach the important skills from the outset while 'tying-in' the relevant theory as progress is made. There are numerous examples and self-test exercises which enhance the learning process and help to embed the knowledge and skills needed to practise the art of celestial navigation.Although it is a large book (containing 324, letter size pages) it is thoroughly cross-referenced and its layout enables the reader to move from one section to another without having to read it from beginning to end. With regard to the mathematical aspects of the subject, the author has adopted a language style which allows the text to flow smoothly and makes for enjoyable reading which is a departure from the stilted, academic language of many text books.Note. The terms celestial navigation and astro navigation are generally regarded as synonymous.

Evidences and commonalities explored from ancient man around the globe!Why structures echoing the Tower of Babel have been recreated on almost every continent and major cultureWhat artifacts and archaeology, technology and innovation, really reveal about the origin of mankindWhy many biblical symbols (rainbows, human sacrifice, mountains, the Son/ sun worship) were, and continue to be, distorted in pagan religious practicesWhat the historical record reveals about Satan's "counterfeit" of God's plan for humanityAll over the world there are similar findings of ancient religions, cities and towers, world travel, advanced astronomy, and civilized government. Over the course of two years, a team of researchers from Jackson Hole Bible College has worked to bring together the different pieces of the convoluted mystery and history of ancient man.Hours of researching, trips to various sites around North and Central America, visits to museums, and meetings with experts have provided the team with an overwhelming amount of evidence for the intelligence of these early innovators. A jumble of anomalies and magnificent structures continue to confound archaeology and anthropology today, yet as the dots are connected, one finds history as described in the biblical record.

The Systems Modeling Language (SysML) extends UML with powerful systems engineering capabilities for modeling a wider spectrum of systems and capturing all aspects of a system’s design. SysML Distilled is the first clear, concise guide for everyone who wants to start creating effective SysML models. (Drawing on his pioneering experience at Lockheed Martin and NASA, Lenny Delligatti illuminates SysML’s core components and provides practical advice to help you create good models and good designs. Delligatti begins with an easy-to-understand overview of Model-Based Systems Engineering (MBSE) and an explanation of how SysML enables effective system specification, analysis, design, optimization, verification, and validation. Next, he shows how to use all nine types of SysML diagrams, even if you have no previous experience with modeling languages. A case study running through the text demonstrates the use of SysML in modeling a complex, real-world sociotechnical system. Modeled after Martin Fowler’s classic UML Distilled, Delligatti’s indispensable guide quickly teaches you what you need to know to get started and helps you deepen your knowledge incrementally as the need arises. Like SysML itself, the book is method independent and is designed to support whatever processes, procedures, and tools you already use. Coverage Includes Why SysML was created and the business case for using it Quickly putting SysML to practical use What to know before you start a SysML modeling project Essential concepts that apply to all SysML diagrams SysML diagram elements and relationships Diagramming block definitions, internal structures, use cases, activities, interactions, state machines, constraints, requirements, and packages Using allocations to define mappings among elements across a model SysML notation tables, version changes, and sources for more information

Astrophysics is often –with some justification – regarded as incomprehensible without the use of higher mathematics. Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented –stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition.

Space weaponry, satellite surveillance and communications, and private space travel are all means in which outer space is being humanized: incorporated into society’s projects. But what are the political implications of society not only being globalized, but becoming ‘cosmic’? Our ideas about society have long affected, and been affected by, our understanding of the universe: large sections of our economy and society are now organized around humanity’s use of outer space. Our view of the universe, our increasingly ‘cosmic’ society, and even human consciousness are being transformed by new relations with the cosmos. As the first sociological book to tackle humanity’s relationship with the universe, this fascinating volume links social theory to classical and contemporary science, and proposes a new ‘cosmic’ social theory. Written in a punchy, student-friendly style, this timely book engages with a range of topical issues, including cyberspace, terrorism, tourism, surveillance and globalization.

This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.
