The astronomer Jan Hendrik Oort (1900-1992) left behind an extensive collection of notes and correspondence, both on his research and on matters that concerned him in a variety of official functions. Upon Oort's death, the collection was augmented by more personal papers, letters, journals, and diaries. The resulting collection forms a rich source of information on many aspects of twentieth-century astronomy, in which Oort played such an important role. The scientific and personal material covers the entire span of time from Oort's early youth until his death. To make these papers accessible to a wide circle of users, the collection has now been catalogued and described; the result is presented in this volume. A name index and a subject index have been added to facilitate access. The inventory is accompanied by a short biographical sketch, and a number of photographs, mostly relating to Oort's career as a scientist. The original papers themselves are archived in the Leiden University Library.

An inventory of the 362 items representing the personal and professional papers of Dutch astronomer Oort (1900-92) held at the Leiden University Library. Lists and describes each document in the item, which often includes manuscripts, comments, outlines, correspondence, and miscellaneous notes. The entries are presented in sections such as research and teaching, the Leiden observatory, astronomy in the Netherlands, and world events. Also includes a biographical sketch, a primary bibliography, a few reproductions, and photographs. Annotation copyrighted by Book News, Inc., Portland, OR

This book is the first thorough and overdue biography of one of the giants of science in the twentieth century, Jan Hendrik Oort. His fundamental contributions had a lasting effect on the development of our insight and a profound influence on the international organization and cooperation in his area of science and on the efforts and contribution of his native country. This book aims at describing Oort's life and works in the context of the development of his branch of science and as a tribute to a great scientist in a broader sense. The astronomer Jan Hendrik Oort from the Netherlands was founder of studies of the structure and dynamics of the Milky Way Galaxy, initiator of radioastronomy and the European Southern Observatory, and an important contributor to many areas of astronomy, from the study of comets to the universe on the largest scales.

This accessible and entertaining biography chronicles the life and triumphs of astronomer Jan Hendrik Oort, who helped lay the foundations of modern astronomy in the 20th century. The book puts into context some of Oort's most significant achievements, including his discovery that the Milky Way rotates, as well as his famous hypothesis that our Solar System is surrounded by a reservoir of comets — now simply known as the Oort Cloud. Written by Oort’s former student, this fascinating story also delves into Oort’s pivotal role in the foundation of major astronomical facilities, including radio telescopes in the Netherlands and the European Southern Observatory (ESO), which now operates the most successful astronomical observatories in the world. The book draws extensively on new archival research through the Oort Archives, along with personal reminiscences by Oort’s son and astronomer-grandson, to paint a more detailed picture of Oort’s life not just as an astronomer, but also as a husband, father, and citizen. The strong public interest in comets triggered by the Rosetta mission to comet 67P/Churyumov–Gerasimenko and the recently discovered interstellar comet in the Solar System make this book particularly timely.

Jacobus Cornelius Kapteyn (1851-1922) of the University of Groningen was one of the foremost astronomers of his time, resulting in a leading role internationally of Dutch astronomy throughout the twentieth century. This volume, which is the proceedings of a special `legacy' symposium at the celebration of the 385th anniversary of the University of Groningen, addresses Kapteyn's influence on the development of modern astronomy through studies of his pioneering work on statistical astronomy and the Structure of the Sidereal System, and his leadership in establishing international collaborations, in particular the Plan of Selected Areas. In addition to historical studies related to Kapteyn's person, work, international collaborations and organisational efforts, the volume discusses the influence of Kapteyn on the internationalisation of astronomy and on contemporary astronomy. It also provides an inventory of Kapteyn's correspondence.

In the 400 years of its modern history the Netherlands has produced a distinguished array of eminent mathematicians, scientists and medical researchers including many Nobel-prize winners and other internationally recognised figures, from Stevin, Snel, and Huygens in the 17th century to Lorentz, Kammerlingh Onnes, Buys Ballot, De Vries, de Sitter, and Oort in the 19th and 20th centuries. Yet it has often been noted that the history of science in the Netherlands is underepresented in the international literature. The handbook A History of Science in The Netherlands aims to correct this situation by providing a chronological and thematic survey of the field from the 16th century to the present, essays on selected aspects of science in the Netherlands, and reference biographies of about 65 important Dutch scientists. Written by more than 10 experts from Europe and North America, the handbook is the standard English-language reference work for the field.

Edited by acclaimed science writer and physicist James Trefil, the Encyclopedia's 1000 entries combine in-depth coverage with a vivid graphic format to bring every facet of science, technology, and medicine into stunning focus. From absolute zero to the Mesozoic era to semiconductors to the twin paradox, Trefil and his co-authors have an uncanny ability to convey how the universe works and to show readers how to apply that knowledge to everyday problems.
