* History: 1939, Lise Meitner and her nephew Otto Frisch, during a Christmas-Eve walk, come up with the idea of nuclear fission (the term was taken from cell biology) while discussing results by Otto Hahn and Fritz Strassmann in Berlin; 1949, Nuclear shell model proposed; 1950s, First clear idea of neutrons and protons in nuclei; 2002, Traditional nuclear physics is "dying" (work is now around engineering applications), and the excitement in the field has moved toward its marriage with astrophysics and understanding of nucleosynthesis in the early universe and in stars, the motivation behind the push for building the RIA (rare-isotope accelerator); 2010, We are entering an era of "nuclear renaissance" motivated by the diminishing supply and increasing cost of fossil fuels and their negative impact on the environment; Nuclear power is seen as an affordable energy source that does not emit CO2, and a new theoretical focus is needed on studies of the materials involved in nuclear energy generation and on fission processes.
* Models / calculations: The oldest model, still fundamentally fine but in practice difficult to calculate with, is the shell model; It can be used, starting with a mean-field approximation with corrections, up to A = 60; Beyond that, use a deformed basis, and apply "angular momentum projection" numerically.
* Current view: The nuclear forces acting between protons and neutrons that are responsible for the nuclear binding are residual color forces, much like the van der Waals forces between neutral molecules.
* Magic numbers: The nuclear shell model explains that nuclei with certain magic numbers (2, 8, 20, 28, 50, 82 and 126) of neutrons and/or protons are especially stable because the neutrons and/or protons form closed shells; Nuclei that contain magic numbers of both protons and neutrons (e.g., nickel-78 and tin-132) are even more stable and are said to be "doubly magic".
* Half-lives: 14C, 5.730 yr; 214Po, ~ 10−4 s; 239Pt, 24,000 yr.
