The pendulum is perhaps the simplest experimental devices ever constructed, and yet for all its simplicity it has historically enabled scientists to both investigate and enumerate gravity; the fundamental force that shapes the very universe. The pendulum has also allowed astronomers and geologists to measure the motion, mass and distribution of matter within the Earth, and its stately swing is at the very heartbeat of time. This book explores the many applications of the pendulum, from its employment as a fundamental experimental device, such as in the Cavendish torsion balance for measuring the universal gravitational constant, to its everyday, practical use in geology, astronomy and horology.
Professor Zdenek Kopal is sixty-seven this year even though his scientific activity, enthusiasm and springy step hardly betray the ad vancement in years. He carne to Manchester as Professor of Astronomy thirty years ago after a very fruitful association of fourteen years with the Harvard Observatory. Much impressed with the young man, Harlow Shapley, who with characteristic insight had recognised in Kopal the qualities that have since made him an outstanding leader in ec1ipsing binary research, had invited him over as a Research Associate. In the subsequent decade Kopal set about the task of introducing analytical rigour in the solution of orbit al elements that hitherto had depended ex c1us...

This book provides a selection of annotated translations from Ernst Kurth's three best-known publications: Grundlagen des linearen Kontrapunkts (1917), Romantische Harmonik und ihre Krise in Wagners 'Tristan' (1920), and Bruckner (1925). Kurth's contemporaries considered these books to be pioneering studies in the music of J. S. Bach, Wagner and Bruckner. Professor Rothfarb's extensive introductory essay discusses the intellectual and socio-cultural environment in which Kurth was writing, referring to aspects of the early twentieth-century cultural renewal movements and to intellectual developments of the day in phenomenology, aesthetics and psychology. By reading Kurth against the cultural-intellectual background provided in the essay and commentaries, today's music historians and theorists can round out their picture of music theory in the early twentieth century.
