The Centre's roster of scientific research and training activities for 2000 will begin 1 February with the joint INFM-ICTP School on Magnetic Properties of Condensed Matter Investigated by Neutron Scattering and Synchrotron Radiation Techniques and end 24 November with the Workshop on Physics of Mesosphere-Stratosphere Interactions with Special Emphasis on MST Radar Techniques. In between, some 40 activities in high-energy physics, condensed matter physics, environmental physics, mathematics and a host of related fields are expected to attract nearly 4000 scientists from around the world. An up-to-date 2000 Scientific Calendar can be found throughout the year on the Centre's web site at http://www.ictp.trieste.it/www_users/calendar/cal2000.html.
