This book contains the most interesting problems from the first 24 years of the 'Mathematical Duel', an annual international mathematics competition between the students of four schools: the Gymnázium Mikuláše Koperníka in Bílovec, Czech Republic, the Akademicki Zespół Szkół Ogólnokształcących in Chorzów, Poland, the Bundesrealgymnasium Kepler in Graz, Austria and the Gymnázium Jakuba Škody in Přerov, Czech Republic.The problems are presented by topic, grouped under the headings Geometry, Combinatorics, Number Theory and Algebra, which is typical for olympiad-style competitions.Above all, it is of interest to students preparing for mathematics competitions as well as teachers looking for material to prepare their students, as well as mathematically interested enthusiasts from all walks of life looking for an intellectual challenge.

This book discusses current challenges related to teaching geography, mainly at the secondary school and higher education level. Focusing on a range of current topics, different methods, techniques, materials, applications, and approaches to geography education with a regional Central European perspective, the book makes an original contribution to the field. Most of the chapters aims at the practical development of the themes such as geography curriculum (Part I), global education, inquiry-based education, project-based learning, case studies, powerful teaching (Part II), using of information and communication technologies (Part III) in geography teaching. The final part (Part IV) covers some geopolitical, and socio-geographical aspects of the aforementioned Central European former communist countries from the point of view how to teach them with various methods. Therefore, the book can appeal to many geography or science students, researchers and educators studying geography education around the world.

This study guide for the Chemistry Olympiad contains summarized concepts and examples in all areas of chemistry. The chapters are arranged in a logical manner and establishes connections between concepts. Undergraduate chemistry concepts are explained clearly: every equation in physical chemistry is derived and justified while every organic reaction has its reaction mechanism shown and explained, without assuming that readers have university-level background in the subject. The book also contains original Chemistry Olympiad sample problems that readers may use to test their knowledge.This is a first book of its kind, written by Nan Zhihan, International Chemistry Olympiad (IChO) gold medallist and winner of the International Union of Pure and Applied Chemistry (IUPAC) Prize for achieving the highest score in the experimental exam, and experienced Chemistry Olympiad trainer Dr Zhang Sheng, who has served as head mentor of Singapore IChO team for many years. It builds on the experience of both a participant and trainer to help any aspiring Chemistry Olympiad student understand the challenging concepts in chemistry.

The term “crisis,” with its complex history, has emerged as one of the pivotal notions of political modernity. As such, reconstructing the ways the discourse of crisis functioned in various contexts and historical moments gives us a unique insight not only into a series of conceptual transformations, but also into the underlying logic of key political and intellectual controversies of the last two centuries. Studying the ways crisis was experienced, conceptualized, and negotiated can contribute to the understanding of how various visions of time and history shape political thinking and, conversely, how political and social reconfigurations frame our assumptions about temporality and spatiality. A historical region wedged in between various competing imperial centers, East Central Europe has been an area often associated with crisis phenomena by both internal and external observers. Seeking to employ the regional gaze as a vantage point to reflect on issues which are relevant well beyond those countries between the Baltic and the Adriatic, this project is also in dialogue with a number of recent transnational attempts to rethink political and intellectual history with regard to the recurrent epistemological frames that structure the political and cultural debate. This book will thus be useful both for researchers, from the field of intellectual history and numerous adjacent fields, and graduate university students alike.

"An extremely useful and much needed survey. Over eleven chapters, authors from eight countries cover the complex history of migration from the perspective of Central and Eastern Europe between 1945 and 1993. Following in the footsteps of Klaus Bade’s Encyclopedia of European Migrations, the authors make extensive use of sources in national languages, while providing an extensive overview of population movements in the region between the Baltic, Black, and Adriatic Seas. The individual chapters shed light on phenomena overlooked in other volumes, including individual state reactions to various migratory phenomenon, and the political, economic, and ideological consequences of human movement. The chapters of this volume are uniform not only in their informative nature, but also in suggesting new pathways for in-depth research." Adam Walaszek, Jagiellonian University, Kraków, Poland "Eastern Europe is an emblematic space of mobility and its Cold War history cannot be told without considering migration from and into the countries of the region. This volume comes at a timely moment and provides a uniquely comprehensive account, full with useful information for further research. It will be a must-read both for migration studies scholars and for area specialists." Ulf Brunnbauer, Leibniz Institute for East and Southeast European Studies, Regensburg, Germany "The Handbook is a gift to students of migration on three counts. It gathers the expertise of scholars fluent in the languages – and familiar with the archives – of Eastern and Central Europe. Thus it brings the multi-layered and complex histories of movement beyond the flat descriptor of "Soviet bloc" or Eastern European migrations. The Handbook is both rich and lucid, presenting in-depth materials on the European twentieth-century, on one hand, and organizing each chapter in a similar way, offering the reader transparently comparable histories. From Estonia south to Albania, and from the USSR west to the GDR, each chapter elucidates a complex migration history distinguished by national politics, ethnic composition, and economics – moving from the cataclysmic impacts of World War II to the international migrations and politics of Cold War movement, as well as the politics of Cold War emigrants themselves. Each chapter ends with an epilogue on post-1989 international migrations and a valuable addendum on published and archival sources. Finally, the Handbook models the kind of high quality work produced by international scholarly cooperation at its best."

This book is composed of the most interesting problems from a quarter century of regional mathematics competitions for students aged 11-14 in the province of Styria, Austria. The problems presented here range from pure puzzles to a more traditional mathematical type of question, but all are somehow special, posed with the intent of giving the reader something interesting to think about, with the promise of an entertaining moment of elucidation and enlightenment at the end.

This book constitutes the refereed proceedings of the 7th International Conference on Informatics in Schools: Situation, Evolution, and Perspectives, ISSEP 2014, held in Istanbul, Turkey, in September 2014. The 13 full papers presented together with 2 keynotes were carefully reviewed and selected from 33 submissions. The focus of the conference was on following topics: Competence Science Education, Competence Measurement for Informatics, Emerging Technologies and Tools for Informatics, Teacher Education in Informatics, and Curriculum Issues.

An international mathematics competition involving number theory, algebra, combinatorics, and geometry. Contestants are students from the Czech Republic, Poland, and Austria. Also called the Mathematical Duel.
