The Sachdev-Ye-Kitaev (SYK) model has a long history in nuclear physics where its precursor  was introducedas 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 ofthe 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.
