In this issue of the ics, more in the spirit of Poincare´ (as expounded by Arnold), NOTES we present excerpts from Sir Michael Atiyah’s preface with its emphasis on geometrical thinking, even in areas such to the volume, followed bt brief quotations from a number of as algebra or number theory. It is worth noting that topol- the essays making up the book. ogy does not figure among the list of Hilbert’s problems, but Poincare,´ in his address to the 1908 Congress, highlighted it (or analysis situs as it was then called) as an important area for the future. It was widely recognised that no single person could now hope to emulate Hilbert by producing a corresponding list of problems. This is not just undue modesty on the part of contemporary mathematicians. It is more a sober reflection on the enormous range and diversity of mathematics in the year 2000. This volume is therefore a collective effort, but the result is not simply a longer list of problems. Different mathematicians have responded in different ways to the chal- lenge. Some have tried to follow the Hilbert paradigm, but restricted themselves to covering a smaller area (e.g., Jones, Smale, Yau). Others write more from a personal or philo- sophical viewpoint (Kirwan, Manin, Ruelle) or review likely developments in certain areas (Baker-Wusholtz, Donaldson, McDuff, Wiles). Some concentrate on more detailed prob- lems in depth (Connes, Kazhdan, Mazur), and it is notewor- thy that Connes reformulates the Riemann Hypothesis (one of Hilbert’s problems) with the full machinery of 20th century Sir Michael Atiyah mathematics. In addition to many articles on theoretical physics, there Hilbert’s problems have stood the test of time remark- are a few on other important areas of applied mathematics ably well.
