Summary

Summary

Geometry, this very ancient field of study of mathematics, frequently remains too little familiar to students. Michle Audin, professor at the University of Strasbourg, has written a book allowing them to remedy this situation and, starting from linear algebra, extend their knowledge of affine, Euclidean and projective geometry, conic sections and quadrics, curves and surfaces. It includes many nice theorems like the nine-point circle, Feuerbach's theorem, and so on. Everything is presented clearly and rigourously. Each property is proved, examples and exercises illustrate the course content perfectly. Precise hints for most of the exercises are provided at the end of the book. This very comprehensive text is addressed to students at upper undergraduate and Master's level to discover geometry and deepen their knowledge and understanding.

Choice Review

Relying merely on the title Geometry, one might imagine many rather different books sandwiched between the covers! One thinks first of axiomatic Euclid, so ancient theorems about triangles and circles or perhaps modern gems such as one finds, say, in Ross Honsberger's Episodes in Nineteenth Century and Twentieth Century Geometry (CH, Nov'95). But one might also get (perhaps too dryly) a comparative text about geometries, one that contrasts the Euclidean, elliptic, hyperbolic, and projective and adds a touch of group theory to bring out the role of symmetry. A differential geometry of curves and surfaces will have a completely different flavor still, even more so a tome on the generalities of Riemannian geometry. Audin (Universite Louis Pasteur), writing for undergraduates who have some linear algebra, selects and unifies a range of topics that actually traverses a good deal of this terrain. Though she chooses foundations based on linear algebra rather than axiomatics, she does develop a suite of classic Euclidean theorems, if mostly as exercises. But her development also proceeds up to Gauss's celebrated "Theorema egregium." Withal, a solid introduction to many faces of modern geometry.The mere fame of a classic book does not automatically guarantee the easy availability of a truly useful and adequate modern edition in translation. Now in this republication of Thomas L. Heath's 1908 Cambridge University Press translation, the editors, with classroom use in mind, have indeed succeeded in their aim of providing a "one-volume, clean, student-friendly, Euclid-centered edition of the complete text of all thirteen books of the Elements.'' As "clean'' here means the omission of Heath's commentaries, the Dover edition will remain a necessity for scholars. But this edition does serve a purpose if, by dint of its gracious typography and layout, it makes a direct confrontation with Euclid not too intimidating for those modern undergraduates who might otherwise never even bother to take a look. ^BSumming Up: Both books--Recommended.
