History of 20th Century

Germany in the 20th century endured two world wars, a failed democracy, Hitler's dictatorship, the Holocaust, and a country divided for 40 years after World War II. But it has also boasted a strong welfare state, affluence, liberalization and globalization, a successful democracy, and the longest period of peace in European history. A History of Twentieth-Century Germany provides a survey of German history during a century of extremes. Ulrich Herbert sees German history in the 20th century as determined by two contradictory perspectives. On one hand, there are the world wars and great catastrophes that divide the country's history into two parts-before and after 1945. Germany is the birthplace of radical ideologies of the left and right and the only country in which each ideology became the foundation of government.

Since the early part of the 20th century, topology has gradually spread to many other branches of mathematics, and this book demonstrates how the subject continues to play a central role in the field. Written by a world-renowned mathematician, this classic text traces the history of algebraic topology beginning with its creation in the early 1900s and describes in detail the important theories that were discovered before 1960. Through the work of Poincaré, de Rham, Cartan, Hureqicz, and many others, this historical book also focuses on the emergence of new ideas and methods that have led 21st-century mathematicians towards new research directions.
