This book not only comprises the standard vector analysis of Gibbs, including dyadics or tensors of valence two, but also supplies an introduction to the algebra of motors, which is apparently destined to play an important role in mechanics as well as in line geometry. The entire theory is illustrated by many significant applications; and surface geometry and hydrodynamics are treated at some length by vector methods in separate chapters.
