The book highlights the personal and scientific struggles of Arthur Erich Haas (1884-1941), an Austrian Physicist from a wealthy Jewish middle-class family, whose remarkable accomplishments in a politically hostile but scientifically rewarding environment deserve greater recognition. Haas was a fellow student of both Lise Meitner and Erwin Schroedinger and was also one of the last doctoral students of Ludwig Boltzmann. Following Boltzmann's suicide, Haas was forced to submit a more independent doctoral thesis in which he postulated new approaches in early quantum theory, actually introducing the idea of the Bohr radius before Niels Bohr. It is the lost story of a trailblazer in the fields of quantum mechanics and cosmology, a herald of nuclear energy and applications of modern science. This biography of Haas is based on new and previously unpublished family records and archived material from the Vienna Academy of Science and the University of Notre Dame, which the author has collected over many years. From his analysis of the letters, documents, and photos that rested for nearly a century in family attics and academic archives, Michael Wiescher provides a unique and detailed insight into the life of a gifted Jewish physicist during the first half of the twentieth century. It also sheds light on the scientific developments and thinking of the time. It appeals not only to historians and physicists, but also general readers. All appreciate the record of Haas' interactions with many of the key figures who helped to found modern physics.

The characterization of cultural heritage objects becomes increasingly important for conservation, restoration, dating, and authentication purposes. The use of scientific methods in archaeometry and conservation science has led to a significant broadening of the field. Scientific analysis of these objects is a challenging task due to their complex composition, artistic and historical values requiring the use of minimally invasive and nondestructive analytical procedures. This textbook summarizes scientific methods that are currently used to characterize objects of cultural heritage and archaeological artifacts. This book provides a brief description of the structure of matter at the molecular, atomic, and nuclear levels. Furthermore, it discusses the chemical and physical nature of materials from the molecular to the atomic and nuclear level as determined by the principles of quantum mechanics. Important aspects of natural and anthropogenic radioactivity that play a critical role for some of the analytical techniques are also emphasized. The textbook also provides principals and applications of spectroscopic methods for characterization of cultural heritage objects. It describes the technologies with specific examples for utilization of spectroscopic techniques in the characterization of paintings, books, coins, ceramics, and other objects. Analytic approaches that employ isotopes and determination of isotope ratios will be reviewed. General principles of imaging techniques and specific examples for utilization of these methods will also be summarized. In the later part of the book, a number of scientific techniques for the age determination of cultural heritage material and archaeological artifacts will be presented and discussed with specific examples.
