,Riemann (1826–1866),Like Mozart’s, Bernhard Riemann’s life was short but marvelously creative. He solved several of the most difficult problems in pure and applied mathematics, introduced entirely new concepts and techniques, and profoundly changed the way in which mathematicians, physicists, and philosophers view space.

The Evolution of Geometry,es give rise. Modem geometry is an extremely active field of research by pure and applied mathematicians, and it also has significant applications in physics and engineering. In the present book, we will explore in a physical manner the geometrical properties of curves and surfaces, and will discuss

Curves,ew of the infinite variety of curves that can be imagined. The path of a bird flying through the air, the instantaneous shape of a swinging chain held at its top, the outlines of petals, the forms of arches and suspension bridges-all provide physical examples of curves. We wish to describe such gene
