Preface
Ein neues Lied, ein besseres Lied, 0 Freunde, will ich Euch dichten! *
A new song, a better song, My friends, I intend to compose you!
What are the important developments in present-day mathematics? Where is mathematics headed? Our anthology attempts to shed light on these questions.
At the dawn of the 20th century, it was possible for one sage individual to survey the whole of mathematics: Hilbert's presentation of twenty-three problems in 1900 not only gave a sense of the direction of mathematics, but also helped it move forward.
The scope of mathematics has expanded enormously over the last hundred years. Scientific and technological advances, in particular the explosive growth of computing power, have created numerous opportunities for mathematics and mathematicians. The core areas of mathematics did not suffer as a result of the proliferating applications; quite to the contrary, "pure mathematics" is thriving, with the invention of powerful theories, the solution of celebrated problems, and the emergence of unforeseen connections between different areas of mathematics and physics, chemistry, computer science.
Can one eminent mathematician, or a small group of eminent mathematicians, afford an overview of the breadth of today's mathematics? We think not, we present a composite of many individual views, out of necessity and conviction. The contributors are leading experts in their fields, ranging all the way from mathematical logic to applications of mathematics in the film industry.
Our volume is not an encyclopedia. Completeness was not the main goal, nor was it an achievable goal. We do hope to provide the reader with a view of the great variety and the vitality of mathematics as we enter the new millennium.
