German-American philosopher of science who developed the deductive-nomological (covering-law) model of scientific explanation and posed the raven paradox for the confirmation theory of science.
Covering-law model (D-N): a scientific explanation is a deductive argument whose premises include at least one law and whose conclusion is the event to be explained. Raven paradox: 'All ravens are black' is equivalent to 'All non-black things are non-ravens' — so observing a green apple confirms 'All ravens are black.' Contributed to functional explanation and the philosophy of psychology.
