The 16th International Spin Physics Symposium, spin2004, will be held during October 10-16, 2004 in Trieste, Italy. The Symposium is open to all scientists, regardless of citizenship and nationality. The Symposium will be organized by the Trieste Section of Istituto Nazionale di Fisica Nucleare (INFN), and will be hosted by the Abdus Salam International Centre for Theoretical Physics (ICTP) in Miramare, Trieste, Italy.

This Symposium is the third joined International Symposium of the Nuclear Spin Physics and High Energy Spin Physics. The International Symposium on High Energy Spin Physics was held every two years. The last one took place at Protvino, Russia, in 1998. The International Symposium on Polarization Phenomena in Nuclear Physics was held every five years. The last one (the 8th Conference) took place at Bloomington, USA, in 1994.

Since the year 2000, the International Spin Physics Symposium series joined together the High Energy Spin Symposia and the Nuclear Polarization Conferences. Thus the scientific programme of this Symposium includes the topics of relevance to spin physics in medium-low energy reactions and polarization phenomena in nuclear physics, as well as those relevant to high energy spin physics. The previous two editions of new series of Symposia were held in Osaka, Japan (October 2000) and at BNL, USA (September 2002), respectively. The Trieste Symposium is the third of the series.

Spin is a key element in the present and future development of particle and nuclear physics. Indeed spin plays a paramount role in studies of fundamental symmetries, static particle properties, and structure of fundamental interactions. Studies of polarized reactions could possibly open the road in the search of new kinds of interactions. Similarly, spin physics will allow decisive progress in the understanding of nuclear reaction dynamics and of the structures of hadron-nucleon many body systems. Technical developments and application of spin physics are also very important.
