By Herbert Busemann
Starting with a short assessment of notations and terminology, the textual content proceeds to convex curves, the theorems of Meusnier and Euler, extrinsic Gauss curvature, and the effect of the curvature at the neighborhood form of a floor. A bankruptcy at the Brunn-Minkowski conception and its functions is by means of examinations of intrinsic metrics, the metrics of convex hypersurfaces, geodesics, angles, triangulations, and the Gauss-Bonnet theorem. the ultimate bankruptcy explores the stress of convex polyhedra, the belief of polyhedral metrics, Weyl's challenge, neighborhood cognizance of metrics with non-negative curvature, open and closed surfaces, and smoothness of realizations.

After learning either classics and arithmetic on the college of Cambridge, Sir Thomas Little Heath (1861-1940) used his time clear of his task as a civil servant to put up many works with reference to old arithmetic, either well known and educational. First released in 1926 because the moment variation of a 1908 unique, this e-book comprises the 3rd and ultimate quantity of his three-volume English translation of the 13 books of Euclid's parts, protecting Books Ten to 13.
