Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.

"Any kind of boating can be fun," the author points out, "racing around the marks, or coastwise cruising where there is almost always at hand visual reference ashore from which bearings can be taken for locating one's position and thus finding one's way home. Severing these ties with land, however, offers a new kind of fun, a new kind of freedom, a freedom from dependence on land." Here is a basic beginner's book, introducing the amateur to the tools, the vocabulary, and the techniques of celestial navigation. Among the recommended tools are the H. O. 249 tables, the most widely used among amateur navigators at sea because of their simplicity. The ability to determine one's position at sea both liberates the sailor from the land and enables him to find his way to his destination. If you can read, add and subtract, understand angles, and use a protractor, you can learn to navigate in your armchair or at sea from Celestial Navigation by H. O. 249.

A poignant, uplifting, heartbreaking love story from the beloved bestselling, Pulitzer Prize–winning author: "To read a novel by Anne Tyler is to fall in love" (PEOPLE). Thirty-eight-year-old Jeremy Pauling has never left home. He lives on the top floor of a Baltimore row house where he creates collages of little people snipped from wrapping paper. His elderly mother putters in the rooms below, until her death. And it is then that Jeremy is forced to take in Mary Tell and her child as boarders. Mary is unaware of how much courage it takes Jeremy to look her in the eye. For Jeremy, like one of his paper creations, is fragile and easily torn—especially when he's falling in love....

Amateur hour has arrived, and the audience is running the show In a hard-hitting and provocative polemic, Silicon Valley insider and pundit Andrew Keen exposes the grave consequences of today’s new participatory Web 2.0 and reveals how it threatens our values, economy, and ultimately the very innovation and creativity that forms the fabric of American achievement. Our most valued cultural institutions, Keen warns—our professional newspapers, magazines, music, and movies—are being overtaken by an avalanche of amateur, user-generated free content. Advertising revenue is being siphoned off by free classified ads on sites like Craigslist; television networks are under attack from free user-generated programming on YouTube and the like; file-sharing and digital piracy have devastated the multibillion-dollar music business and threaten to undermine our movie industry. Worse, Keen claims, our “cut-and-paste” online culture—in which intellectual property is freely swapped, downloaded, remashed, and aggregated—threatens over 200 years of copyright protection and intellectual property rights, robbing artists, authors, journalists, musicians, editors, and producers of the fruits of their creative labors. In today’s self-broadcasting culture, where amateurism is celebrated and anyone with an opinion, however ill-informed, can publish a blog, post a video on YouTube, or change an entry on Wikipedia, the distinction between trained expert and uninformed amateur becomes dangerously blurred. When anonymous bloggers and videographers, unconstrained by professional standards or editorial filters, can alter the public debate and manipulate public opinion, truth becomes a commodity to be bought, sold, packaged, and reinvented. The very anonymity that the Web 2.0 offers calls into question the reliability of the information we receive and creates an environment in which sexual predators and identity thieves can roam free. While no Luddite—Keen pioneered several Internet startups himself—he urges us to consider the consequences of blindly supporting a culture that endorses plagiarism and piracy and that fundamentally weakens traditional media and creative institutions. Offering concrete solutions on how we can reign in the free-wheeling, narcissistic atmosphere that pervades the Web, THE CULT OF THE AMATEUR is a wake-up call to each and every one of us.

A radical manifesto about doing what you love Andy Merrifield offers a passionate tribute to the revolutionary spirit of the amateur—a figure who thinks outside the box, takes risks, dreams the impossible dream, seeks independence, and carves out a new world. Merrifield celebrates such square pegs as Charles Baudelaire, Fyodor Dostoevsky, Edward Said, Guy Debord, Hannah Arendt, and Jane Jacobs, each of whom shows us a path of unconventional wisdom and freedom. The Amateur advocates urgently for the liberated life, one that creates the space to question authority.

Simple Celestial is an instructional manual on the art of celestial navigation. The manual is clear, succinct and thorough in presenting in a simple style the process of observing the Sun, Moon, planets and stars used in celestial navigation in order to derive a position fix any where in the world. The process of celestial navigation as presented in the manual uses an assumed position to derive an intercept that is the basis for a line of position from the heavenly body. Additionally, the manual explains the alternate method of observing the Sun at local apparent noon for a position fix. Using either method and with the appropriate supporting tools, the student will find the manual an excellent guide in completing the sight reduction form to arrive at a solution. The manual deliberately relegates theory to a small chapter in the back, concentrating rather on the practical aspects of celestial navigation.

To the uninitiated, celestial navigation appears to be a somewhat frightening exercise in mathematics. In fact, the maximum mathematics involved in the new sight reduction systems is the addition of three lines of figures. Similarly, the apparent complexities of the solar and stellar systems take on a less frightening appearance when related to the lighthouses and similar earthly objects used for coastal navigation. Throughout this book, the author uses such a comparison between earthly and heavenly objects in explaining the close relationship between coastal and celestial navigation. In doing so, he reduces a complex subject to a simple and interesting one that can be absorbed by even the most non-mathematically minded. The book concentrates for much of its length on the plotting of the boat's position by sun, planets, and stars when out of sight of land. It also deals with related navigational routines such as checking the compass by using heavenly objects, taking radio time signals, and adjusting the sextant for day-to-day corrections. This is celestial navigation in its simplest form, presented in a way which even the most amateur navigator can understand and absorb.
