An Observer of Observatories
Thomas Bugge, director of the observatory in Copenhagen, kept a diary during his travels in Germany, Holland and England in 1777. He described his meetings with leading scientists, artists and instrument makers, and the many scientific institutions he visited. The diary is also full of drawings of the buildings, technical devices and instruments he saw. Bugge's diary is now available in an English translation with an introduction and notes by historians of science Kurt Moller Pedersen and Peter de Clercq.

An Observer of Observatories
"In 1777, the Danish astronomer Thomas Bugge (1740-1815) was appointed professor of mathematics and astronomy at the University of Copenhagen. Keen to modernise the existing observatory on top of the Round Tower, he travelled through Germany to Holland and England to learn more about the state of astronomy and instrument-making in these countries. During his tour he kept a journal in which he noted what he saw, whom he met and which books and instruments he bought. He also included dozens of sketches and drawings, which greatly add to the historical value of his manuscript. The document lay undiscovered in the Royal Library at Copenhagen until 1969, when Kurt Moller Pedersen found it and prepared a provisional transcript. Forty years later, this journal is now made available and Bugge's drawings are complemented by portraits of academics and instrument-makers and by photographs of buildings and instruments, many of which survive in museums today. This richly illustrated and fully annotated edition of Bugge's travel journal will be of value for anyone who is interested in the history of science and technology in the 18th century."--Back cover.
The Moon that Wasn't
The planet Venus is the closest neighbour to the Earth and in several respects similar to our globe. It revolves around the Sun at an average distance of 0. 72 astronomical units, in an elliptical orbit of eccentricity 0. 007. The corresponding 3 numbers for the Earth are 1 and 0. 017. The mean density of Venus is 5. 2 g/cm , 3 that of the Earth 5. 5 g/cm . Venus’ acceleration of gravity at its equator is 8. 9 2 2 m/s , compared with 9. 8 m/s at the Earth. The escape velocity is 10. 4 km/s, while the corresponding ?gure of the Earth is 11. 2 km/s. Although the mass of Venus is somewhat smaller than that of the Earth – the ratio is M /M =0. 815 V E – the diameters of the two planets are almost the same. In other words, Venus is indeed a sister planet of the Earth. In earlier times, when almost nothing was known about the physical con- tions of Venus, the similarity appeared even stronger than today. Not only was Venus’ period of rotation thought to be close to that of the Earth, it was also p- sible (and indeed common) to imagine intelligent life on Venus.
A General History of Horology
A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamental, new and original research.
Between Rhetoric and Reality
"Felix Meritis, the remarkable 'Temple of Enlightenment', adorns the Amsterdam canals since 1788. The building accommodated the most ambitious attempt in the Netherlands for the integration of activities regarding literature, music, the visual arts, commerce, and the sciences. What so far went unnoticed is that, from the very start, Felix Meritis was also equipped with an astronomical and meteorological observatory. In fact, it was the first scientific observatory in the Netherlands designed from the drawing board. This book describes the history of the observatory (which functioned until 1889), with a special focus on the tensions between the objectives formulated by its founding fathers and the ultimate difficult practice of scientific research. The Felix Meritis-Observatory was crucial for the training and early careers of various eighteenth- and nineteenth-century astronomers, among which Nieuwland, Van Beeck Calkoen, Moll, Keijser, Uylenbroek, and Kaiser (the father of modern Dutch astronomy)."--Cover.
Huygens: The Man Behind the Principle
Huygens: The Man Behind the Principle is the story of the great seventeenth-century Dutch mathematician and physicist, Christiaan Huygens (1629-1695). As the first complete biography ever written this book describes in detail how Huygens arrived at discoveries and inventions that are often wrongly ascribed to Newton. Huygens played a key role in the 'scientific revolution', and the Huygens Principle on the wave theory of light helped establish his reputation. The discovery of Saturn's rings and the invention of the pendulum clock made him so famous that he was invited to be the first director of the French Academy of Science, but his life as director teetered on the edge of powerlessness. Despite Huygens' many achievements no complete biography has previously been published in English. This book gives scientists and historians the opportunity to learn more about all aspects of Huygens' life while bringing his story to a wider audience.
