Due cacciatori di lontre della Compagnia Russo-Americana, Sandoe e Mac-Doll, vengono imbarcati su un sottomarino contro la loto volontà. Si ritrovano così a far parte dell'equipaggio del Taimyr, un geniale e futuristico battello subacqueo dalle possibilità infinite, comandato dal misterioso ingegnere Nikirka, coadiuvato da un equipaggio di provata fedeltà. La missione del Taimyr è raggiungere il Polo Nord navigando esclusivamente sotto le acque. Pur con con alcuni imprevisti e difficoltà, la meta viene raggiunta. Il ritorno, invece, riserva delle conseguenze impreviste. Dopo la perdita del Taimyr e dell'intero equipaggio, il solo Mac-Doll, che dovrà lasciar morire l'amico Sandoe, sarà miracolosamente salvato da una nave di passaggio.

This impressive compilation offers a nearly complete listing of sound recordings made by American minority artists prior to mid-1942. Organized by national group or language, the seven-volume set cites primary and secondary titles, composers, participating artists, instrumentation, date and place of recording, master and release numbers, and reissues in all formats. Because of its clear arrangements and indexes, it will be a unique and valuable tool for music and ethnic historians, folklorists, and others.

Includes the Proceedings of the Royal geographical society, formerly pub. separately.

In this important volume, major events and personalities of 20th century physics are portrayed through recollections and historiographical works of one of the most prominent figures of European science. A former student of Enrico Fermi, and a leading personality of physical research and science policy in postwar Italy, Edoardo Amaldi devoted part of his career to documenting, both as witness and as historian, some significant moments of 20th century science. The focus of the book is on the European scene, ranging from nuclear research in Rome in the 1930s to particle physics at CERN, and includes biographies of physicists such as Ettore Majorana, Bruno Touschek and Fritz Houtermans.Edoardo Amaldi (Carpaneto, 1908 - Roma, 1989) was one of the leading figures in twentieth century Italian science. He was conferred his degree in physics at Rome University in 1929 and played an active role (as a member of the team of young physicists known as ?the boys of via Panisperna?) in the fundamental research on artificial induced radioactivity and the properties of neutrons, which won the group's leader Enrico Fermi the Nobel Prize for physics in 1938. Following Fermi's departure for the United States in 1938 and the disruption of the original group, Amaldi took upon himself the task of reorganising the research in physics in the difficult situation of post-war Italy. His own research went from nuclear physics to cosmic ray physics, elementary particles and, in later years, gravitational waves. Active research was for him always coupled to a direct involvement as a statesman of science and an organiser: he was the leading figure in the establishment of INFN (National Institute for Nuclear Physics) and has played a major role, as spokesman of the Italian scientific community, in the creation of CERN, the large European laboratory for high energy physics. He also actively supported the formation of a similar trans-national joint venture in space science, which gave birth to the European Space Agency. In these and several other scientific organisations, he was often entrusted with directive responsibilities. In his later years, he developed a keen interest in the history of his discipline. This gave rise to a rich production of historiographic material, of which a significant sample is collected in this volume.

Focusing on extreme environments, from Umberto Nobile’s expedition to the Arctic to the commercialization of Mt Everest, this volume examines global environmental margins, how they are conceived and how perceptions have changed. Mountaintops and Arctic environments are the settings of social encounters, political strategies, individual enterprises, geopolitical tensions, decolonial practises, and scientific experiments. Concentrating on mountaineering and Arctic exploration between 1880 – 1960, contributors to this volume show how environmental marginalisation has been discursively implemented and materially generated by foreign and local actors. It examines to what extent the status and identity of extreme environments has changed during modern times, moving them from periphery to the centre and discarding their marginality. The first section looks at ways in which societies have framed remoteness, through the lens of commercialization, colonialism, knowledge production and sport, while the second examines the reverse transfer, focusing on how extreme nature has influenced societies, through international network creation, political consensus and identity building. This collection enriches the historical understanding of exploration by adopting a critical approach and offering multidimensional and multi-gaze reconstructions. This book is essential reading for students and scholars interested in environmental history, geography, colonial studies and the environmental humanities.

This book, the last of the series dedicated to the solar system, includes various aspects of different kinds of planets during their evolution over the centuries, like the seasons, the length of the day, the precession, the orbital elements of the planets, the date of Easter and much more. A chapter is also dedicated to the transits and occultations visible to the other planets. This is not a technical and difficult to read manual, but a complete and very detailed description of what the sky gives us throughout our lives, so each table is ready for use, and each reported event will be easily visible to the naked eye or possibly with a simple pair of binoculars. The book is for stargazing astronomers and professionals. Questo libro, l'ultimo della serie dedicata al sistema solare, include vari aspetti di diversa natura dei pianeti affrontati nella loro evoluzione nel corso dei secoli, come le stagioni, la durata del giorno, la precessione, gli elementi orbitali dei pianeti, la data della Pasqua e ta
