Topical Meeting on Nuclear Physics and Astrophysical Neutrinos,
27 - 28 September 1999, Nordita, Copenhagen.

In connection with a visit by Nordita's Adjunct Professor Wolfram Weise from the Technical University of Munich it is planned to hold a workshop on the problem of interactions between neutrinos and dense matter in astrophysical contexts, and relevant related nuclear physics issues. Possible topics to be taken up are likely to include tensor and spin correlations in hot and cold dense matter, neutrino opacities and luminosities in supernovae and neutron stars, and possibly the composition of dense matter. For more details consult Chris Pethick. (pethick@nordita.dk)

Methods Meet: Physics and Topical Issues of Society
4 - 5 November 1999, Nordita, Copenhagen.

Human activities are increasingly influencing local and global environments. Our societies are facing difficult choices in regulating activities which affect, e.g., climate (global warming), natural resources (energy use, fishing quotas) and pollution levels. The structure of social interactions (in communications and finance, for example) is likewise growing more complex.

Optimal responses to such challenges should be guided by evaluations of competent scientists. Physicists are trained to understand interrelations between complex phenomena, and they increasingly apply their skills in multidisciplinary research of direct relevance to society.

Nordita wishes to promote the discussion of these issues by orgainizing the workshop 'Methods Meet: Physics and Topical Issues of Society' at Nordita on 4-5 November 1999. The program includes:

• B. Gustafsson, Uppsala Univ.: The broader significance of fundamental physics in the world today;
• R. Czujko, American Institute of Physics: Career choices of physics graduates;
• H. Svensmark, Danish Space Research Institute: Climate;
• K. Magnusson, Univ. of Iceland: Natural resources;
• P.G. Hjorth, Technical Univ. of Denmark: European study groups with industry;
• S. Svanberg, Lund Institute of Technology: Interactions of research driven by curiosity and purpose;

There will be discussions on topics such as:
• Promoting the awareness of graduate students of challenging problems in other areas (through invited lectures, summer schools, etc.)
• The opportunities for interdisciplinary research in areas of direct relevance to society (positions, research grants, etc.)
• The views of applied research institutes and industry
• Contacts between scientists and regulatory agencies

The program and registration form can be found at http://www.nordita.dk/Adm/Conf/hoyer/MethodsMeet.html. Graduate students are encouraged to apply.
For further information contact Paul Hoyer (hoyer@nordita.dk) or Ellen Pedersen (pedersen@nordita.dk).

Minischool on Stochastic Finance
2 - 4 December 1999, Nordita, Copenhagen.

As a part of our non-equilibrium statistical physics initiative at Nordita we plan to arrange a minischool on Stochastic Finance in December 1999. The format of the school will be a series of lectures dealing with the nature of economic systems as seen from a physics perspective. We will invite lecturers to cover the latest develop-ments in game theory, in fluctuation analysis and Black-Scholes theory for risk minimization, and in various ways of viewing self-organization in economic systems. The school will take 3 days and is preliminarily scheduled for 2-4 December. For further information please contact Kim Sneppen, e-mail: sneppen@nordita.dk.

Spåtind 2000: The 16th Nordic Meeting in Particle Physics
