On the Hypotheses Which Lie at the Bases of Geometry

“It is a modern version of the classical Riemann’s lecture about developments in the geometry and the birth of the Riemannian geometry. … it brings the basic concepts and the necessary mathematical background that will help you to read this important and classical piece of work that was Riemann’s lecture on geometry. … interesting not only to mathematicians but also to physicist and philosophers. It is an interesting and well-crafted book and I recommend it to your personal library.” (Philosophy, Religion and Science Book Reviews, bookinspections.wordpress.com, June, 2016)
