Book Description
Latitude Hooks and Azimuth Rings is for people who like to work with their hands and who appreciate traditional nautical craftsmanship. You don't have to be the master of any craft to undertake any of these projects--from a simple kamal or latitude hook to the more complex pelorus or octant--just a careful and enthusiastic worker. These 18 projects fall roughly into three categories: decorative, useful, and somewhere in between. Some, such as the astrolabe, are mainly for display. On the other hand, the sounding line is an important and practical tool for small-craft navigation, particularly in the absence of an electronic sounder. The cross-staff falls somewhere in between, equally at home in the den or the ditch kit. Each of the devices discussed here--with simple, proven building instructions complemented by clear illustrations--has at one time or another been used for the practical business of navigation, and each is worth reviving for its beauty, historic value, or sheer usefulness. Dennis Fisher has designed these projects with an emphasis on simplicity and reasonable cost. Everything can be scratch-built using easily obtainable materials and tools, and each is true to the spirit and function of the original instrument.

Book Description
Heroism and horror abound in these true stories of 16 great explorers who journeyed to the Arctic and Antarctic regions, two exquisite and unique ice wildernesses. Recounted are the exciting North Pole adventures of Erik the Red in 982 and the elusive searches for the &“Northwest Passage&” and &“Farthest North&” of Henry Hudson, Fridtjof Nansen, Fredrick Cook, and Robert Peary. Coverage of the South Pole begins with Captain Cook in 1772; continues through the era of land grabbing and the race to reach the Pole with James Clark Ross, Roald Amundsen, Robert Scott, and Ernest Shackleton; and ends with an examination of the scientists at work there today. Astounding photographs and journal entries, sidebars on the Inuit and polar animals, and engaging activities bring the harrowing expeditions to life. Activities include making a Viking compass, building a model igloo, making a cross staff to measure latitude, creating a barometer, making pemmican, and writing a newspaper like William Parry's &“Winter Chronicle.&” The North and South Poles become exciting routes to learning about science, geography, and history.

Book Description
This guide to making wooden sundials gently leads beginning diallists into sundial lore and construction. Novice craftsmen who can wield a saw, wood-burning pen, matte knife, sandpaper and a few other simple tools can make five different kinds of sundials; plans are flexible and allow for embellishment, alteration, variety of materials. Precalculated templates can be removed from the book and carbon-paper-transferred to wood.

Book Description
Spherical trigonometry was at the heart of astronomy and ocean-going navigation for two millennia. The discipline was a mainstay of mathematics education for centuries, and it was a standard subject in high schools until the 1950s. Today, however, it is rarely taught. Heavenly Mathematics traces the rich history of this forgotten art, revealing how the cultures of classical Greece, medieval Islam, and the modern West used spherical trigonometry to chart the heavens and the Earth. Glen Van Brummelen explores this exquisite branch of mathematics and its role in ancient astronomy, geography, and cartography; Islamic religious rituals; celestial navigation; polyhedra; stereographic projection; and more. He conveys the sheer beauty of spherical trigonometry, providing readers with a new appreciation for its elegent proofs and often surprising conclusions. Heavenly Mathematics is illustrated throughout with stunning historical images and informative drawings and diagrams that have been used to teach the subject in the past. This unique compendium also features easy-to-use appendixes as well as exercises at the end of each chapter that originally appeared in textbooks from the eighteenth to the early twentieth centuries. -- Jacket.
