In July 2009 Germany hosted the 50th International Mathematical Olympiad (IMO). For the very first time the number of participating countries exceeded 100, with 104 countries from all continents. Celebrating the 50th anniversary of the IMO provides an ideal opportunity to look back over the past five decades and to review its development to become a worldwide event. This book is a report about the 50th IMO as well as the IMO history. A lot of data about all the 50 IMOs are included. We list the most successful contestants, the results of the 50 Olympiads and the 112 countries that have ever taken part. It is impressive to see that many of the world’s leading research mathematicians were among the most successful IMO participants in their youth. Six of them gave presentations at a special celebration: Bollobás, Gowers, Lovász, Smirnov, Tao and Yoccoz. This book is aimed at students in the IMO age group and all those who have interest in this worldwide leading competition for highschool students.
This Invitation to Mathematics consists of 14 contributions, many from the world's leading mathematicians, which introduce the readers to exciting aspects of current mathematical research. The contributions are as varied as the personalities of active mathematicians, but together they show mathematics as a rich and lively field of research. The contributions are written for interested students at the age of transition between high school and university who know high school mathematics and perhaps competition mathematics and who want to find out what current research mathematics is about. We hope that it will also be of interest to teachers or more advanced mathematicians who would like to learn about exciting aspects of mathematics outside of their own work or specialization. Together with a team of young ``test readers'', editors and authors have taken great care, through a substantial ``active editing'' process, to make the contributions understandable by the intended readership.
Problem-solving journal at the senior secondary and university undergraduate levels for those who practice or teach mathematics. Primarily educational in purpose, it also serves those who read it for professional, cultural and recreational reasons.
The first full-length study of the literary criticism on the works of the controversial twentieth-century German writer Hans Henny Jahnn.
Though often depicted as a rapid political transformation, the Nazi seizure of power was in fact a process that extended from the appointment of the Papen cabinet in the early summer of 1932 through the Röhm blood purge two years later. Across fourteen rigorous and carefully researched chapters, From Weimar to Hitler offers a compelling collective investigation of this critical period in modern German history. Each case study presents new empirical research on the crisis of Weimar democracy, the establishment of the Nazi dictatorship, and Hitler’s consolidation of power. Together, they provide multiple perspectives on the extent to which the triumph of Nazism was historically predetermined or the product of human miscalculation and intent.
Diese Einladung zur Mathematik besteht aus 14 Beiträgen, viele davon von weltweit führenden Mathematikern geschrieben, die die Leser in spannende Aspekte aktueller mathematischer Forschung einführen. Die Artikel sind so vielfältig wie die Persönlichkeiten ihrer Autoren und zeigen, wie reich und lebendig die Mathematik als Forschungsgebiet ist. Das Buch richtet sich in erster Linie an interessierte Schüler und junge Studierende, die Mathematik aus der Schule oder von Wettbewerben kennen und die aktuelle Forschungsmathematik kennenlernen wollen. Zusammen mit einem Team junger "Testleser" haben die Herausgeber und Autoren in einem intensiven Bearbeitungsprozess die Texte für junge Leser verständlich gestaltet. Schüler, Lehrer, Mathematiker und alle Mathematik-Begeisterten werden in diesem vielseitigen und spannenden Buch genussvoll lesen.
Dieses Buch wird alle Liebhaber der Mathematik (und die es werden wollen) durch eine Fülle von reizvollen und unterhaltsamen Problemstellungen aus Algebra, Geometrie, Kombinatorik und Zahlentheorie begeistern. Vierzig ausgewählte Aufgaben aus 50 Jahren Bundeswettbewerb Mathematik werden mit ausführlichen Lösungen, Einblicken in das mathematische Umfeld und inhaltlichen Variationen reich illustriert präsentiert. Von der Mathematik geht für viele seit jeher eine besondere Faszination aus. Wer tiefer in sie eindringt, entdeckt ihre Schönheit, ihre Eleganz und ihre unendliche Vielfalt und stößt immer wieder auf überraschende Resultate. Hiermit bereits bei Schülerinnen und Schülern In...
