... periodizations to be developed in the history of particle physics. In the timeframe considered, it is argued that inferential strategies were used to interpret single images of particle tracks, that evidence aggregation was crucial using all kinds of detectors, and that it was also common to use nuclear physics...

... because there would be no way to detect two photons at the same time at two different detectors, assuming a photon as a small localized indivisible particle. The debate over the HBT results was intense, so intense, indeed, that, as remarked later by Hanbury Brown, some physicists even went as far as to...
