In Memoriam: Professor Emeritus Kari Lumme


Planetary astronomer Professor Emeritus Kari Lumme passed away at home in Espoo, Finland on November 23, 2013, due to a sudden and unexpected health problem. Kari Lumme worked at the Observatory, University of Helsinki, for more than 30 years. He was Professor of Astronomy from 1985 until his retirement in 2006. He continued to work as Professor Emeritus at the Observatory and, after a department merger, at the Department of Physics. Kari Lumme acted as the Director of the Observatory, University of Helsinki in 1992-1997.


He was born in Oulu, Finland on July 19, 1942. Kari Lumme received his M.Sc. degree at the University of Oulu in 1965 and his Ph.D. degree at the University of Helsinki in 1973. Kari Lumme spent extended periods of time at foreign research institutes. In the years 19711980, he visited the University of Manchester, Meudon Observatory in Paris, University of Massachusetts at Amherst, and Lowell Observatory in Flagstaff, Arizona. In 1994-1995, Kari Lumme worked as Visiting Professor at the Department of Physics and Astronomy, Free University of Amsterdam. Together with his local hosts, he organized a scientific meeting on light scattering by nonspherical particles. This meeting became the first of its kind in a regular long-term series, with meetings organized, for example, in Helsinki in 1997 and 2010.


Kari Lumme`s scientific career can be viewed as being composed of three time periods. In 1965-1980, he carried out theoretical photometric research on Saturn`s rings, the Moon, Mars, and small Solar System bodies like asteroids and natural satellites. This period culminated in the publications of the so-called Lumme-Bowell model for the diffuse reflection on light by the surfaces of atmosphereless objects and a Nature article on Saturns rings. Thereafter, the years 1981-1994 consisted of several milestones in light scattering and inverse methods. The methods were applied to Solar System objects such as the martian moon Phobos and the main-belt asteroid Gaspra. The years 1994-2006 were the period of exact electromagnetic scattering methods and computations. As a result of this work, nonspherical small particles were shown to cause a negative linear polarization branch near backscattering, accompanied by increased backscattering, in close resemblance to the observations of, e.g., cometary dust. At the same time, Kari Lumme initiated industrial applications of the scattering methods, particularly in the paper and pigment industry. In total, Kari Lumme published over one hundred peer-reviewed scientific articles.


Kari Lumme supervised numerous Ph.D. and M.Sc. theses. Daily, comprehensive scientific discussions with the chalk sticks and the blackboard in his office constituted an essential part of the supervision. These discussions were cross-disciplinary, as Kari Lumme had postgraduate students from, e.g., theoretical physics and mathematics, in addition to astronomy. With the cross-disciplinary approach, he and his research group succeeded in resolving a number of long-lasting open problems in scattering of light by atmosphereless planetary objects. These include explanations for the opposition effect and negative linear polarization observed for atmosphereless objects as well as the foundation for lightcurve inversion for an asteroids rotation period, pole orientation, and convex shape.


Kari Lumme was an ambitious and enthusiastic researcher. He often worried about research results being left unpublished in his drawer due to the next incoming science question demanding attention from him. In the summer time, with his family and friends, Kari Lumme sailed on the Baltic Sea and beyond, and spent time at the cottage in Kustavi.

New Book by Our Colleague

Hidden Worlds in Quantum Physics (Dover Books on Physics) by Dr. Gerard Gouesbet

The past decade has witnessed a resurgence in research and interest in the areas of quantum computation and entanglement. This new book addresses the hidden worlds or variables of quantum physics. Author Gerard Gouesbet studied and worked with a former student of Louis de Broglie, a pioneer of quantum physics. His presentation emphasizes the history and philosophical foundations of physics, areas that will interest lay readers as well as professionals and advanced undergraduate and graduate students of quantum physics. The introduction is succeeded by chapters offering background on relevant concepts in classical and quantum mechanics, a brief history of causal theories, and examinations of the double solution, pilot wave, and other hidden-variables theories. Additional topics include proofs of possibility and impossibility, contextuality, non-locality, classification of hidden-variables theories, and stochastic quantum mechanics. The final section discusses how to gain a genuine understanding of quantum mechanics and presents a refutation of certain hidden-variable theories, including pilot wave.
