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.

Planetary
and Space Science. Special Issue on Cosmic Dust VII
The 7th
meeting on Cosmic Dust (Cosmic Dust VII) is held at Umeda
Satellite Campus of Osaka Sangyo University, Osaka, Japan from Monday, August
4, 2014 through Friday, August 8, 2014. This special issue of Planetary and
Space Science will be primarily devoted to Cosmic Dust VII and contain the
papers presented at this particular meeting. However, it is also open to
submission of any other papers that discuss some aspect of cosmic dust. All
kinds of cosmic dust are the subject of discussion. Papers on dust-related
topics, for example, the formation of molecules and their reactions on and their desorption from the surface of cosmic dust, are also
welcome.
In
particular, the topic of interest includes but is not limited to
intergalactic dust

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.
