This book offers an introduction to differential geometry for the non-specialist. It includes most of the required material from multivariable calculus, linear algebra, and basic analysis. An intuitive approach and a minimum of prerequisites make it a valuable companion for students of mathematics and physics. The main focus is on manifolds in Euclidean space and the metric properties they inherit from it. Among the topics discussed are curvature and how it affects the shape of space, and the generalization of the fundamental theorem of calculus known as Stokes' theorem.

This book offers an introduction to the theory of differentiable manifolds and fiber bundles. It examines bundles from the point of view of metric differential geometry: Euclidean bundles, Riemannian connections, curvature, and Chern-Weil theory are discussed, including the Pontrjagin, Euler, and Chern characteristic classes of a vector bundle. These concepts are illustrated in detail for bundles over spheres.

Člověk dobré vůle, jehož originál vyšel v Rotterdamu roku 1936, patří do řady knih, ve kterých je s výraznou zkratkou pozorován život vesnice a města, kde je s ideovým důrazem kritizován a napravován. Jeho děj je dějem vzatým opravdu ze života, a přece má v sobě něco, ba mnoho z onoho poselství božího, o kterém mluví autor.
