Revised and Extended Edition of `Practical Work in Elementary Astronomy' by M.G.J. Minnaert
Several decades have elapsed since the publication of any similar book in the German language. The lack of such a book has been felt keenly by all friends of astronomy. In our space age, astronomical knowledge arouses public interest more and more. Practical observation at the telescope depends more than anything else on such knowledge. The educational value of such a training is undisputed. On the other hand, the work of the amateur astronomer can also contribute essentially to the work of the professionals. It is from these points of view that this handbook aims to help with versatile advice. At the same time, the book intends to show the wide range of applied astronomy, as it presents itself to the friend of the stars; in mathematical-physical fields, in precision mechanics and optics, and last but not least in the area of social relations. Beyond the circle of amateur astronomers the book is addressed to lecturers, teachers, students and pupils. It wishes to serve them as a guide to "astronomical experiments", which we suggest should be performed in primary and secondary schools, specialist colleges, and extramural courses.
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.
Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysies, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 44 records literature published in 1987 and received before February 15, 1988. Some older documents which we received late and which are not surveyed in earlier volumes are inc1uded too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. Dr. Siegfried Böhme retired from his duties as co-editor of Astronomy and Astro physics Abstracts on December 31, 1987. Since 1950 he partieipated in the biblio graphie work of the institute. He served as a reviewer for the Astronomischer Jahresbericht and became one of the editors of Astronomy and Astrophysics Ab stracts in 1969. After his retirement in 1975 he took care of, particularly, the Russian literature on a voluntary basis for 12 years. It is a pleasure to thank Siegfried Böhme for his valuable contributions. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Christiane Jehn, Ms. Monika Kohl, Ms.
One of the biggest difficulties in astronomy is establishing the limits of observational errors in order to avoid inadequate or incorrect interpretation of data. This requires a thorough understanding of the methods used by astronomers used to calculate distances, diameters, temperatures ages and other parameters and an ability to assess their reliability. Such methods range from the simplest techniques, which have been used since ancient times, to extremely sophisticated computer based techniques. Both have their uses, and the simple methods are still used today to give a first approximation.
All of science springs from the observation of nature. In this classic book, the late Professor Minnaert accompanies the reader on a tour of nature's light and color and reveals the myriad phenomena that may be observed outdoors with no more than a pair of eyes and an enquiring mind. From the intriguing shape of the dapples beneath a tree on a sunny day, via rainbows, mirages, and haloes, the colors of liquid, ice, and the sky, to the appearance of the sun, moon, planets, and stars - Minnaert describes and explains them all in a clear language accessible to laymen. This new English edition is supplemented by 80 plates, over half of them in color, taken by the acclaimed photographer Pekka Parviainen, illustrating many of the phenomena - ordinary and exotic - discussed in the book.
