DESCRIPTION:Systems in contact with multiple reservoirs fall i
 n nonequilibrium states characterized by sustained
  currents of energy and matter. While in small sys
 tems thermal fluctuations are accounted for by Mas
 ter (or Fokker-Planck) equations\, in infinite-siz
 e systems the dynamics is described by determinist
 ic rate equations which may display\, inter alia\,
  multistability and limit cycles. At large but fin
 ite sizes\,  nonequilibrium conditions induce meta
 stability\, namely\, small fluctuations within mac
 roscopic attractors and rare random transitions be
 tween them. This is the regime of interest for man
 y natural and man-made systems\, ranging from (bio
 )chemical reaction networks to electronic circuits
 . Using concepts of large deviations theory\, I wi
 ll explain such nonequilibrium emergent behavior f
 rom the microscopic stochastic dynamics and descri
 be how (stochastic) thermodynamics can be consiste
 ntly formulated through all levels of description.
