Target audience armchair adventurer. Second edition includes a chapter on preparing for an ocean crossing.

Sailors have been navigating the seas for thousands of years, and navigational technology has progressed exponentially during that time. This concise yet comprehensive volume begins with the impressive developments in navigation made by early navigators and follows the art and science of navigation through the ages to their culmination in the huge advances made by our contemporaries. With a focus on the navigational tools invented by each age and civilization, Launer traces the evolution of humankind¿s navigational skills from the Kamal of the Arabs and the Lead-line first used by the Romans to the radio and satellite communication devices available to modern sailors. He pays homage to the Polynesians who, in the absence of a written language were able to pass down their navigational skills through generations, and to the adventurous Vikings, who managed to find their way from Scandinavia to England, Iceland, Greenland and beyond; but he also covers the practical applications of the complex technologies found on most boats today, such as GPS. Generous illustrations help readers envision the tools in use. Navigation Through the Ages will appeal to sailors and lay readers alike¿anyone with an interest in the history of science and the exploration of our world.

The main intent of this book is to prepare the North American sailor for his first crossing of the Atlantic to Europe. It is actually so exhaustive in its coverage that it will indeed help the bluewater sailor to learn how to cross any ocean in the world.

Applied Mathematics: Made Simple provides an elementary study of the three main branches of classical applied mathematics: statics, hydrostatics, and dynamics. The book begins with discussion of the concepts of mechanics, parallel forces and rigid bodies, kinematics, motion with uniform acceleration in a straight line, and Newton's law of motion. Separate chapters cover vector algebra and coplanar motion, relative motion, projectiles, friction, and rigid bodies in equilibrium under the action of coplanar forces. The final chapters deal with machines and hydrostatics. The standard and content of the book covers C.S.E. and 'O' level G.C.E. examinations in Applied Mathematics and Mechanics as well as the relevant parts of the syllabuses for Physics and General Science courses related to Engineering, Building, and Agriculture. The book is also written for the home study reader who is interested in widening his mathematical appreciation or simply reviving forgotten ideas. The author hopes that the style of presentation will be found sufficiently attractive to recapture those who may at one time have lost interest.

'An assured debut that unashamedly harks back to classic thrillers... reads like a knowing blend of John Buchan's The 39 Steps and Robert Louis Stevenson's Treasure Island.' - The Irish Times A ship adrift, all hands dead. A lighthouse keeper murdered in the night. The Crown needs a man to find the truth. Doctor Mungo Lyon, his reputation tarnished by the Burke & Hare scandal, and forbidden to practise as a surgeon, is the wrong man. That's exactly why the Crown chose him.

"Pullman offers his readers essential insights into how humans reason and make decisions. Both concise and far-reaching, his work teaches us how to challenge intuitive logic and examine the processes for deliberative reasoning. This text will prove foundational for students in their intellectual journey toward the development of real skills in critical thinking. By pointing to simple yet profound examples, Pullman's text is both readable and provocative as it challenges us to consider the very mechanisms by which we understand our own cognitive biases." --Bradley A. Hammer, Department of English and Comparative Literature, University of North Carolina, Chapel Hill

Coursing through the Atlantic Ocean is a powerful current with a force 300 times that of the mighty Amazon. Ulanski explores the fascinating science and history of this sea highway known as the Gulf Stream, a watery wilderness that stretches from the Caribbean to the North Atlantic. Spanning both distance and time, Ulanski's investigation reveals how the Gulf Stream affects and is affected by every living thing that encounters it--from tiny planktonic organisms to giant bluefin tuna, from ancient mariners to big-game anglers. He examines the scientific discovery of ocean circulation, the role of ocean currents in the settlement of the New World, and the biological life teeming in the stream.
