One of the primary goals of nuclear physics is to describe nuclei and their dynamics in terms of interactions between nuclear constituents.
In addition, high-precision experimental data and sophisticated calculations are very important for other research fields such as astrophysics and neutrino physics.
Three topics are discussed by comparing experimental data with recent theoretical calculations; three-nucleon force effects in few nucleon systems, polarization phenomena and spin-isospin responses in quest of a comprehensive description of nuclei, and applications to neutrino physics.
