The history of the Jewish people is complex; it is a history spanning centuries of migration after expulsion from Jerusalem and Judea by Titus in 77 AD. The Jewish people spread and settled throughout the entire Roman Empire and stayed after its collapse. Large Jewish populations are known to have settled in the regions along the Upper Rhine valley, close to the former border of Germania. They had their settlements, their trade, their temples and their rabbis. One of the most famous was Rashi who lived in that area in the 11th century, preaching and teaching the Talmud. This story follows a branch of the descendants of Rashi through the turbulent times of the Crusades, which eradicated most of the Jewish communities in the Alsace and along the Upper Rhine valley. Many found refuge in the Ghetto of Frankfurt, the Judengasse, where for centuries and many generations they lived under the protection of city and emperor. One of these descendants broke with Jewish tradition during the time of the Enlightenment and converted to Christianity, adopting a new name and becoming the pedigree of a new family branch, the Rottensteins. While the first Rottenstein generation emerged as early revolutionaries, fighting for freedom and liberty in Germany, they were exiled and spread across Europe with one branch emigrating to the United States. The fate of the Rottenstein family reflects the history and development of their times. This book follows the different family branches, leading in some cases to scientific and cultural fame and in other cases to false claims of origin and heritage, but in most cases to success in the emerging modern world.

Focusing on the development and modern applications of radioactivity, this volume serves as an accessible introduction to the topic. As the second part of a two-volume set, it delves into both historical advancements and contemporary uses, making complex concepts understandable for readers.

Focusing on the life of Arthur Erich Haas, the narrative explores his personal and scientific challenges as an Austrian physicist from a privileged Jewish background. It sheds light on his significant achievements amidst a politically hostile climate, emphasizing the need for greater acknowledgment of his contributions to science. The book paints a portrait of resilience and determination in the face of adversity, highlighting both his intellectual legacy and the broader context of his time.

Offering a clear and engaging overview, this book serves as an accessible introduction to the concept of radioactivity. It breaks down complex scientific principles into understandable segments, making it suitable for readers new to the subject. Through informative explanations and relatable examples, it aims to demystify the topic and foster a deeper understanding of radioactivity and its implications in various fields.

Offering a clear introduction to radioactivity, this volume is divided into two parts: one focusing on the principles of radiation physics and the other on natural radiation exposure. As the first in a two-volume set, it aims to make complex concepts understandable for readers, providing foundational knowledge essential for further exploration of the subject.

Der Einfluss von Radioaktivität auf die Erde und das Leben wird umfassend untersucht. Wiescher beleuchtet, wie diese natürliche Erscheinung, die ihren Ursprung in alten Sterngenerationen hat, die Bildung und Dynamik unseres Planeten geprägt hat. Zudem wird die Rolle der Radioaktivität in der Entstehung und Entwicklung des Lebens auf der Erde thematisiert, was zu einem tieferen Verständnis der Zusammenhänge zwischen kosmischen Prozessen und biologischen Entwicklungen führt.

Die wachsende Bedeutung von Radioaktivität in der modernen Welt wird in diesem Buch umfassend behandelt. Neben den bekannten Themen wie Kernenergie und Kernwaffen beleuchtet der Autor auch die vielfältigen Anwendungen in der Landwirtschaft, Industrie, Medizin und Kunstgeschichte. Er thematisiert die zunehmende Belastung durch radioaktive Strahlung im menschlichen Umfeld und bietet zahlreiche Beispiele zur Veranschaulichung. Zudem werden die Herausforderungen der Endlagerung und Entsorgung langlebiger radioaktiver Stoffe sowie die damit verbundenen technischen Probleme ausführlich diskutiert.
