Abstract: The discovery of nuclear fission has profoundly impacted human society. There is still strong motivation for its study, not only because of its implications for new soughtafter applications, but also because fission is a unique and complicated many-body quantum dynamical phenomenon. There has been significant theoretical and experimental progress in recent years, which has brought fresh knowledge to our understanding of the nuclear fission process. It is expected that a more accurate and consistent theory of nuclear fission in the future will shed new light on new applications.
