This volume is the first international collection of the best physics problems (both theoretical and experimental) given at the national physics competitions for high school students in different countries. The book introduces the short history of the International Physics Olympiad, the Statutes, the Syllabus, the statistical data including complete list of winners and a collection of national reports. Each of the national report will contains — as a main part — the best theoretical and experimental problems (with complete solutions) given at the national competition or at the training of the team before the international competition. Taking into account that at present the International Physics Olympiad involves about 35 countries, we are sure that the book will be interesting for everybody involved with physics education not only with the physics olympiads.

This vividly illustrated history of the International Congress of Mathematicians- a meeting of mathematicians from around the world held roughly every four years- acts as a visual history of the 25 congresses held between 1897 and 2006, as well as a story of changes in the culture of mathematics over the past century. Because the congress is an int

This book develops the idea that since decolonisation, regional patterns of security have become more prominent in international politics. The authors combine an operational theory of regional security with an empirical application across the whole of the international system. Individual chapters cover Africa, the Balkans, CIS Europe, East Asia, EU Europe, the Middle East, North America, South America, and South Asia. The main focus is on the post-Cold War period, but the history of each regional security complex is traced back to its beginnings. By relating the regional dynamics of security to current debates about the global power structure, the authors unfold a distinctive interpretation of post-Cold War international security, avoiding both the extreme oversimplifications of the unipolar view, and the extreme deterritorialisations of many globalist visions of a new world disorder. Their framework brings out the radical diversity of security dynamics in different parts of the world.

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.

The New York Times bestselling author of The Origins of Political Order offers a provocative examination of modern identity politics: its origins, its effects, and what it means for domestic and international affairs of state In 2014, Francis Fukuyama wrote that American institutions were in decay, as the state was progressively captured by powerful interest groups. Two years later, his predictions were borne out by the rise to power of a series of political outsiders whose economic nationalism and authoritarian tendencies threatened to destabilize the entire international order. These populist nationalists seek direct charismatic connection to “the people,” who are usually defined in narrow identity terms that offer an irresistible call to an in-group and exclude large parts of the population as a whole. Demand for recognition of one’s identity is a master concept that unifies much of what is going on in world politics today. The universal recognition on which liberal democracy is based has been increasingly challenged by narrower forms of recognition based on nation, religion, sect, race, ethnicity, or gender, which have resulted in anti-immigrant populism, the upsurge of politicized Islam, the fractious “identity liberalism” of college campuses, and the emergence of white nationalism. Populist nationalism, said to be rooted in economic motivation, actually springs from the demand for recognition and therefore cannot simply be satisfied by economic means. The demand for identity cannot be transcended; we must begin to shape identity in a way that supports rather than undermines democracy. Identity is an urgent and necessary book—a sharp warning that unless we forge a universal understanding of human dignity, we will doom ourselves to continuing conflict.
