Long regarded as a masterpiece in content and form, this work defines the concept of surface curvature and presents the important theorem stating that the "Gauss curvature" is invariant under arbitrary isometric deformation of a curved surface. This edition of Gauss's classic features a new introduction, bibliography, and notes by science historian Peter Pesic. 1902 edition. Republication of the Princeton, 1902 edition, with a new introduction and notes by Peter Pesic.
