A book by Etienne Ghys, mathematician at Laboratory of Pure and Applied Mathematics (UMPA)
A stroll in the mathematical world. This is neither an elementary introduction to the theory of singularities, nor a specialized treatise containing many new theorems.
The purpose of this little book is to invite the reader on a mathematical promenade. We pay a visit to Hipparchus, Newton and Gauss, but also to many contemporary mathematicians. We play with a bit of algebra, topology, geometry, complex analysis, combinatorics, and computer science.
Hopefully some motivated undergraduates and some more advanced mathematicians will enjoy some of these panoramas.
