This 2019 edition of The American Practical Navigator (Bowditch), Pub No. 9, exists to codify the latest body of marine navigation knowledge and practical application. Its publication success is a result of the dedicated efforts of many hands and voices from academia, science and seafaring experts. This edition has advanced from the judiciously shaped recommendations-some comprehensive, some minute, all indispensable-of a multitude of maritime and science professionals. At the same time, it was equally essential that those recommendations be compared, vetted, and applied in a consistent manner and with a clear vision, a challenging task performed in exemplary fashion by this edition's principal editor, Dr. Gerard J. Clifford, Jr.

In this engagingly written biography, Tamara Plakins Thornton delves into the life and work of Nathaniel Bowditch (1773-1838), a man Thomas Jefferson once called a "meteor in the hemisphere." Bowditch was a mathematician, astronomer, navigator, seafarer, and business executive whose Enlightenment-inspired perspectives shaped nineteenth-century capitalism while transforming American life more broadly. Enthralled with the precision and certainty of numbers and the unerring regularity of the physical universe, Bowditch operated and represented some of New England's most powerful institutions—from financial corporations to Harvard College—as clockwork mechanisms. By examining Bowditch's pathbreaking approaches to institutions, as well as the political and social controversies they provoked, Thornton's biography sheds new light on the rise of capitalism, American science, and social elites in the early republic. Fleshing out the multiple careers of Nathaniel Bowditch, this book is at once a lively biography, a window into the birth of bureaucracy, and a portrait of patrician life, giving us a broader, more-nuanced understanding of how powerful capitalists operated during this era and how the emerging quantitative sciences shaped the modern experience.

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1920 Excerpt: ...is the same as the latitude of the point on the line A', R/J 25 19'.4 S. B115 31.5 W. We now have two Sumner linee, A'and B', under Case I, whose common latitude is 25 19MS., and whose longitudes on the common parallel are 114 61K.7 and 115 31'.5. Hence, the difference of longitude on the common parallel is 115 31'.5 W. 114 59'.7 W. CHAPTER XVI. THE PEAOTIOE 01 NAVIGATION AT SEA. 381. Having set forth in previous chapters the methods of working dead reckoning and of solving problems to find the latitude, longitude, chronometer correction, and azimuth from astronomical observations, it will be the aim of the present chapter to describe the conditions which govern the choice and employment of the various problems, together with certain considerations by which the navigator may be guided in his practical work at sea. 382. Departure And Dead Reckoning.--On beginning a voyage, a good departure must, be taken while landmarks are still in view and favorably located for the purpose; this becomes the origin of the dead reckoning, which, with frequent new departures from positions by observation, is kept up to the completion of the voyage, thus enabling the mariner to know, with a fair degree of accuracy, the position of his vessel at any instant. At the moment of taking the departure, the reading of the patent log (which should have been put over at least long enough previously to be regularly running) must be recorded, and thereafter at the time of taking each sight and at every other time when a position is required for any purpose, the log reading must also be noted. It is likewise well to read the log each hour; for general information as to the speed of the vessel as well as to observe that it is in proper running order and that the rotator has not been fouled ...

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.

This book is one of a kind with analysis of near 8000 records of foods tested in Canada for glyphosate by Canadian Food Inspection Agency (CFIA recently. Tests cover foods from over 60 countries, the bulk of which were foods produced in Canada and the United States, followed by India and China. No other country has conducted this many tests on food for glyphosate and no other analysis exists on this data as of now.North American foods are most contaminated by glyphosate, the active ingredient in Monsanto's Roundup weed killer, the most used herbicide in the planet.The book is over 300 pages long, with over 70,000 words, and more than 300 tables. The data is sorted in chapters, on glyphosate in food according to country of origin, and separately as per food types, such as grains, beans, flour, lentils, fruits, vegetables, and ready made meals, organic and gluten free foods. A lot of raw data figures are included.Attention is given to foods produced in North America, which contribute a bulk of the samples, followed by foods from India and China and a comparison between them. Some of the findings were as expected while some are totally unexpected, and often shocking.Here are a few examples:1) Canada and USA produce the most toxic foods on the planet, with regard to glyphosate contamination.2) Within North America, Canada produces foods with significantly higher levels of glyphosate.3) Within Canada, the west is where one can find more glyphosate contaminated foods than from other regions within Canada. Western Canada is ground zero, for finding nasty foods.5) Cleanest of food suppliers are Peru, Thailand, France, South Africa, Mexico, and China. China apparently exports cleaner foods than what locals consume inside China. For example, imported foods from China, averaging 3 ppb contamination, is 28 times cleaner than foods produced in the US, and over 45 times cleaner than foods produced in Canada.6) Foods imported from Mexico is 70 times cleaner than Canadian foods and over 40 times cleaner than foods originating in the United States.7) Conventional foods desiccated by glyphosate is far more contaminated with glyphosate than roundup ready GM crops.8) Out of the main cereals, rice is about the only one that is more or less without any glyphosate, except for some rice and rice-products produced in North America.9) Lentils and chickpea (garbanzo) produced in North America, as well as foods made with these ingredients are highly contaminated with glyphosate.10) Although soy flour may contain high glyphosate, tofu made out of soy has none.11) Wheat bran produced in Canada has an average of around 2,500 ppb of glyphosate in every sample.12) Organic foods are much better than conventional foods, but are not completely free of glyphosate. Gluten free foods are a mixed bag since some of them are high on glyphosate content, while others are clean.The author maintains that as long as safety data based on which glyphosate was approved for use in agriculture is kept out of reach of the public, and as long as independent verification of the results is denied, there is no proof that glyphosate is safe at any level of contamination. This book is meant to be a useful guide for people that have already reached a conclusion that glyphosate is an unwanted chemical to be in their food and would rather have a tool that helps them avoid it in their selection of foods to buy and eat.Retired EPA scientist Dr. Vallianatos wrote a review on Huffington Post:http://www.huffingtonpost.com/entry/tainting-the-cornucopia-of-north-america_us_58decd30e4b0ca889ba1a5cf
