 The issue of the interpretation of quantum mechanics is strictly related to the issue of the possibility of offering a representation: a description of what happens in the world. It can be useful to give a simple-minded pictorial representation of the images sustaining different interpretations. Imagine at time \(t_1\) a radioactive atom is surrounded by Geiger counters and at time \(t_2\) one of the counters clicks, having detected a product of the decay. What has happened around the \(t_1\)-\(t_2\) interval?
