• "When attached to the new high-gain photomultiplier tubes and strung into the array of amplifiers, pulse-height analyzers, and scalers that emerged from the Rad Lab and Los Alamos, then and only then did the scintillator and Cerenkov radiation became part of the material culture of postwar physics."
• "4The continuity of technology traced from Dagmar Pettersson's version of the scintillation counter in 1923 to Karlik's 1933 counter equipped with a photocell and Blau's 1945 detector endowed with photomultiplier is striking."
• "• This coherent emission of bioluminescence (having the characteristics of a \ "bio-laser\" emission) was demonstrated by using high technology and methodology, such as a photomultiplier, that is able to determine the Poissonian Photocount Statistics of a \ "biophoton emission\" and the hyperbolic-like relaxation of \ "delayed luminescence\" by analyzing the \ "biophoton emission\" and the"
