The ICTP calendar of events for 2005 has just been published. The calendar lists 42 activities-colleges, colloquia, conferences, schools and workshops-on subjects ranging from nanoscience to superstrings, from regional weather prediction to quantitative ecology, and from soil physics to computational cosmology. Activities focusing on turbulence and vortex rings will take place for the first time. Six of the nine activities outside of Trieste will be held in Africa (Egypt, Ghana, Namibia, Niger, and Tanzania); the other three in Cuba, Indonesia, and the Islamic Republic of Iran. To review ICTP's 2005 calendar of activities, see www.ictp.it. The calendar will be continually updated on the web.
