Comment on Griffiths about locality, realism and Bell experiments
... Experiments in physics usually consist of getting information about physical systems in specific states. A particular state is obtained after an appropriate preparation and the information is usually got via measurments. To be general enough I will consider that the result of the measurement is stat ...
