During this talk, I will give a basic introduction to the physics of quantum impurities and the numerical renormalization group (NRG) method - a versatile tool allowing for very accurate treatment of general quantum impurity problems. I will also discuss the extension of NRG to the time domain and present some recent results on the quantum quench dynamics of quantum dot systems, involving also superconducting contacts.
