The Sachdev-Ye-Kitaev (SYK) model has a long history in nuclear physics where its precursor was introduced
as a model for the two-body nuclear interaction to describe the spectra of complex nuclei. Most notably,
its level density is given by the Bethe formula and its level correlations are consistent with chaotic motion of
the nucleons. Recently, this model received a great of attention as a solvable model for the quantum states of
a black hole, exactly because of these properties. In this lecture we introduce the SYK model from a nuclear
physics perspective and discuss its chaotic nature and its relation with black hole physics. We end with a summary
of recent work on two SYK models coupled by a spin-spin interaction as a model for wormholes.
