By Brian Fagan

In Beyond the Blue Horizon, archaeologist and historian Brian Fagan tackles his richest subject but: the long-lasting quest to grasp the oceans, the planet's so much mysterious terrain. we all know the stories of Columbus and Captain cook dinner, but a lot past mariners made both daring and world-changing voyages. From the instant whilst historic Polynesians first dared to sail past the horizon, Fagan vividly explains how our mastery of the oceans replaced the process human heritage.

What drove people to probability their lives on open water? How did early sailors release the secrets and techniques of winds, tides, and the celebs they prompt via? What have been the earliest ocean crossings like? With compelling element, Fagan finds how seafaring developed in order that the forbidding nation-states of the ocean gods have been reworked from obstacles right into a nexus of trade and cultural trade. From bamboo rafts within the Java Sea to triremes within the Aegean, from Norse longboats to sealskin kayaks in Alaska, Fagan crafts an enthralling narrative of humanity's urge to problem the unknown and search out far away beaches. Beyond the Blue Horizon will enthrall readers who loved Dava Sobel's Longitude, Simon Winchester's Atlantic, and Jared Diamond's Guns, Germs, and Steel.

Sample text

In some cases, the molded surface will be the actual exterior surface of the hull, but more often it is a simplified or idealized surface whose choice is strongly influenced by the construction method. The molded surface usually excludes any local protrusions from the hull, such as keel, strakes, chines, and guards. When the vessel is constructed as a skin over frames, the molded surface is usually defined as the inside of skin, outside of frames; this is the case for both metal and wood construction.

A mapping between two surfaces is a rule that associates each point on one surface with a point on the other. When the surfaces are parametric, with the same parameter range, a simple rule is that the associated points are the ones with the same parameter values (u, v) on both surfaces. The mappings we consider here are in that class. An important mapping is the flat development or expansion of a curved surface, generally referred to in shipbuilding as plate expansion. , geodesic distances between any pair of corresponding points on the 3-D surface and the flat development are identical.

Compared with B-rep solids, their data structures and required programming support are very simple and reliable. , an embedded body-fitted 3-D coordinate system u, v, w which allows the unique identification of any interior point, and a way to describe any variation of properties within the solid. Parametric solids are very useful for generating “block-structured” grids and finite elements for various forms of discretized analysis in volumes.
