DESCRIPTION:Using lattice QCD\, one can study hadrons and their interactio
 ns starting from quantum chromodynamics. In the baryon-baryon sector\, thi
 s offers the prospect of a first-principles basis for nuclear physics. I w
 ill discuss the methodology and challenges of these calculations and prese
 nt a study of the conjectured H dibaryon\, a bound state of hyperons with 
 quark content uuddss\, at a single SU(3)-flavour-symmetric quark mass poin
 t. For the first time\, an extrapolation to zero lattice spacing was perfo
 rmed\, which had an unexpectedly large effect on the binding energy. Conce
 rning nucleon-nucleon interactions\, I will review the status of past calc
 ulations and present some work in progress.
