Some 800 scientists from 50 countries will meet for the 25th International Nuclear Physics Conference. The event is organised by the Italian Institute for Nuclear Physics and the Universities of Florence, Padua and Milan The 25th International Nuclear Physics Conference - INPC2013 - will take place in Florence (Italy) from 3-7 June. The event is organised by the Italian Institute for Nuclear Physics and the Universities of Florence, Padua and Milan, under the chief patronage of the President of the Italian Republic and endorsed by the Regional Council of Tuscany and Florence City Council. Some 800 scientists from about 50 countries are expected to attend. The triennial conference, sponsored by the nuclear physics section of the IUPAP (International Union of Pure and Applied Physics) is hosted by cities around the world where nuclear physics research is carried out. Talks will address the heavy-ion collisions achieved at CERN (to study the primordial universe in the immediate aftermath of the Big Bang), but above all they will highlight research being conducted at other accelerator facilities around the world: scientists here study the internal structure of atomic nuclei under "exotic" conditions (very unlike those normally present in our day-to-day world, but similar to those of stars) and of the actual nucleons, the building bricks of atomic nuclei. Other topics will include theoretical and technological research and applications in the fields of medicine, cultural heritage and the environment. The latter will be the subject of the opening conference, a public lecture on applications of techniques developed in nuclear physics laboratories in the fields of cultural heritage and environmental monitoring. The lecture will be held on 2 June at 7:00 pm in the Sala Verde at the Palazzo dei Congressi.
