The Father, the Son, and the Stars: Bengt Strömgren and the History of Twentieth Century Astronomy in Denmark and in the USA

”This book will be of great interest to anyone interested in the development of modern astrophysics in Europe and America in the 20th Century.”

“Danish astronomy in the 20th Century can be typified as the “Strömgren Century” since two generations of Strömgrens dominated the field for much of that time. First Elis and then Bengt Strömgren occupied the coveted directorship at Copenhagen Observatory, and both held highly influential positions within international circles. Elis was devoted to classical astronomy whereas Bengt, stimulated by the quantum revolution then happening in Copenhagen, deftly combined observatory practice with the power of this newest of the new astronomies. This monograph, largely a collective biography, explores the father-son relationship that shaped much of astronomical culture in Denmark. It also contrasts Danish astronomy to American astronomy, since Bengt spent over sixteen years in the United States at the University of Chicago’s Yerkes Observatory, and then at the Institute of Advanced Study in Princeton, where he took over Albert Einsteins office.”

/David DeVorkin, Senior Curator at the National Air and Space Museum, Smithsonian Institution

“I worked with Bengt Stromgren in the 1960’s on the problem of stellar evolution of stars with masses equal to and some 7 times greater than the Sun. When I heard about this book I immediately began a search on Amazon and there it was. It is a very well crafted piece of work and would be doubtless enjoyed by professional and amateur astronomers. ***** A fine book”

Ideudvikling ved kreativ innovation

500x0Idea Development and Creative Innovation (title in English) is a textbook that shows the importance of creativity, innovation and the possibility of systematic idea development. The book defines the concepts and is firmly based on theory of science. “Idea Development by Creative Innovation” puts the concepts in perspective with a historical and normative view, providing a broad and useful understanding of the entire creation process. With the idea-ladder as a basis (Thought – Idea – Solution) and with an introduction to the concept “Creative Idea Solution”, this book gives the reader a concrete model for a process on the verge of chaos that can become a controlled change process.

Milne’s cosmophysics: A study of E. A. Milne’s life course and his attempt to reform physics

This work constitutes my Master’s thesis from 2000. It has been kindly made avaliable by the Center for Science Studies, Aarhus University.

milne's cosmophysicsEven though Edward Arthur Milne (1896-1950) is almost forgotten today he was probably one of the most important and notable figures in prewar cosmology when his ideas to a considerable extent set the agenda in the discussion on the fundamental concepts and methods of cosmology. From the perspective of the history of science Milne is interesting because his scientific works covered a wide field, and his career was split into an orthodox and scientifically fruitful astrophysical phase (ca. 1920-1935) and a more heterodox cosmological phase (ca. 1932-1950).

In the first period Milne was one of the leading astrophysicists (Milne’s equations, Saha’s equation); and the thesis gives a biographical account of his years until 1932. Under the impression of a general excitement over the expanding universe, in 1932 Milne began to focus his interests on cosmology, a field of which he had not previously shown any interest. He developed an original cosmological scheme very different from general relativity, and his ambitious project was to reform physics by means of a new theoretical foundation, his kinematical relativity. His methodological and epistemological ideas aroused the relatively new cosmological community, especially in England (the cosmological principle, the Robertson-Walker metric).

During the thirties, philosophical controversy between the rationalistic ‘cosmophysicists’ and the more empirically-minded scientists affected the models and methods of cosmological science. Milne’s project can be labelled as a potential paradigm, and by analysis of his published works and some unpublished manuscipts and correspondence, the case study of Milne makes an exciting example of conceptual changes in theoretical physics.
