““There is field for every particle. If that field is concentrated in some spatial region, the particle of that field is likely to be located in that region once a detector looks for it. We introduced fields as abstract quantities associated with space; we describe a field as an excitation of space that oscillates like tall grasses in a heavy wind. Recall, however, that there is no material aspect to these field oscillations. Rather, a field is a field is a field.””
