This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.

This book explores the interactions between science and music in the late nineteenth- and early twentieth century. It examines and evaluates the work of Hermann von Helmholtz, Max Planck, Shohé Tanaka, and Adriaan Fokker, leading physicists and physiologists who were committed to understanding crucial aesthetic components of the art of music, including the standardization of pitch and the implementation of various types of intonations. With a mixture of physics, physiology, and aesthetics, author Erwin Hiebert addresses throughout the book how just intonation came to intersect with the history of keyboard instruments and exert an influence on the development of Western music. He begins with the work of Hermann von Helmholtz, a leading nineteenth-century physicist and physiologist who not only made important contributions in vision, optics, electrodynamics and thermodynamics, but also helped advanced the field of music theory as well. The author traces the Helmholtzian trends of thought that become inherently more complex by reaching beyond the sciences to perform a bridge with aesthetics and the diverse ways in which the human mind interprets or is taught, in different cultures, to interpret and understand music. Next, the author explores the works of other key physicists and physiologists who were influenced by Helmholtz and added to his legacy. He examines Japanese music theory student Shohé Tanaka, who sought to design a harmonium that was not based on equal temperament but rather on just intonation. Dutch physicist Adriaan Daniel Fokker, who arranged for organs to be built based on 31-tones per octave, orchestrated concerts for these new instruments and even attempted to compose microtonal music, or music whose tonality is based on intervals smaller than the typical twelve semitones of Western music.

Bertolt Brecht's extraordinary historical novel presents an aspiring scholar's efforts to write an idealized life of Julius Caesar twenty years after his death. But the historian abandons his planned biography, confronted by a baffling range of contradictory views. Was Caesar an opportunist, a permanently bankrupt businessman who became too big for the banks to allow him to fail – as his former banker claims? Did he stumble into power while trying to make money, as suggested by the diary of his former slave? Across these different versions of Caesar's career in the political and economic life of Rome, Brecht wryly contrasts the narratives of imperial progress with the reality of grasping self-interest, in a sly allegory that points to the Weimar Republic and perhaps even to our own times. Brecht reminds his readers of the need for constant vigilance and critical suspicion towards the great figures of the past. In an echo of his dramatic theories, the audience is confronted with its own task of active interpretation rather than passive acceptance -- we have to work out our own views about Mr Julius Caesar. This edition is translated by Charles Osborne and features an introduction and editorial notes by Anthony Phelan and Tom Kuhn.
