On September 14, 1716, Boston Light became the first lighthouse established in Colonial America. With many ships floundering in the treacherous waters of the Massachusetts harbor, there was a great need for navigational aid. At night and during storms, it was difficult to discern the entrance to the main shipping channel of Nantasket Roads, situated between the Brewster islands and the town of Hull. The ledges had become a graveyard for ships, resulting in great loss to human life and cargo--a deterrent to European colonization efforts. Ship captains and merchants petitioned the colonial government for a lighthouse to be erected on Little Brewster Island as a way of safe passage to the inner harbor. Three hundred years later, Boston Light continues to serve its purpose. Today, the lighthouse is protected by an ever-present Coast Guard civilian keeper and a cadre of specially trained Coast Guard Auxiliary volunteer assistant keepers.

Ten Canadian experts make one powerful argument: Canadians cannot shy away from failure if we hope to succeed. We are defined as much by what we have attempted as what we have achieved — and from the lightbulb to the Avro Arrow, Canada’s attempts have been mighty. As Canada turns 150, we look back at the hard lessons learned along the way.

The 13th edition of this bestselling book is proof of the success of Mary Blewitt's concise and clear style in explaining a particularly difficult skill, and it has been the bible for many generations of ocean navigators. Since this book was first published, the huge advances in electronic navigation have transported most offshore navigators to a world of press-button convenience. However, there is still a vital need for traditional skills when things go wrong: batteries can fail, aerials go overboard, and electronics have been known to get wet. A bestseller for over 65 years, Celestial Navigation for Yachtsmen is a model of simplicity and clarity. The worked examples require only straightforward addition and subtraction, which explains why this book has truly earned its reputation for admirable conciseness and for making a tricky subject easy to understand. This edition has been thoroughly revised by Andy Du Port, the highly respected ex-editor of Reeds Almanacs.

LA FASCINANTE HISTORIA DE LAS IDEAS E INVENTOS QUE HAN REVOLUCIONADO LA ECONOMÍA Y EL MUNDO. Imagina que hoy se acabara el mundo y fueras uno de los pocos afortunados supervivientes. Sin móvil. Sin internet. Sin electricidad. Sin gasolina. Hace doce mil años, un invento tan simple como el arado transformó la vida de la humanidad y el curso de la Historia... ¿Qué necesitarías hoy para mantenerte con vida y salvar la civilización? A través de las fascinantes historias de cincuenta ideas e inventos, el autor de El economista camuflado explica cómo la innovación puede cambiar nuestras vidas y alterar el complejo sistema económico global. Algunos inventos, como el iPhone, han proporcionado pingües beneficios a sus creadores mientras otros fueron en sus inicios un fracaso comercial, como el motor diésel. Algunos son palpables, como el hormigón. Otros, como la responsabilidad limitada de una empresa, son invenciones abstractas. Pero todos -del papel a la inteligencia artificial, de la cadena de frío a los seguros, del gramófono a la píldora anticonceptiva- tienen una historia que contar y permiten comprender el mundo en el que vivimos. "Harford demuestra de nuevo su talento como analista económico y divulgador." - Times Literary Supplement Libro del año del Financial Times, Bloomberg Business Week y Amazon Top 20. ENGLISH DESCRIPTION A lively history seen through the fifty inventions that shaped it most profoundly, by the bestselling author of The Undercover Economist and Messy. Who thought up paper money? What was the secret element that made the Gutenberg printing press possible? And what is the connection between The Da Vinci Code and the collapse of Lehman Brothers? Fifty Inventions That Shaped the Modern Economy paints an epic picture of change in an intimate way by telling the stories of the tools, people, and ideas that had far-reaching consequences for all of us. From the plough to artificial intelligence, from Gillette’s disposable razor to IKEA’s Billy bookcase, bestselling author and Financial Times columnist Tim Harford recounts each invention’s own curious, surprising, and memorable story. Invention by invention, Harford reflects on how we got here and where we might go next. He lays bare often unexpected connections: how the bar code undermined family corner stores, and why the gramophone widened inequality. In the process, he introduces characters who developed some of these inventions, profited from them, and were ruined by them, as he traces the principles that helped explain their transformative effects. The result is a wise and witty book of history, economics, and biography.

The Coast Guard's deepest roots run through Massachusetts, the ancestral home to three of the five predecessor agencies that make up the service today. The Coast Guard formed in 1915 and since that time has served the citizens of the Bay State at lifeboat stations, air stations, lighthouses, LORAN stations, and radio stations, as well as on lightships and cutters of all sizes. They have protected the Massachusetts coastline during numerous wars, performing some of the most dramatic rescues in American history--from the Pendleton to the Argo Merchant to the Etrusco and more. The story of the Coast Guard in Massachusetts is one of heroism, honor, respect, and devotion to duty.
