The following passage appears in the preface to the first edition of P. Morse’s Vibration and Sound (1936).
The vacuum tube and the other applications of electronics have provided immensely powerful tools for the measurement, recording, and reproduction of sound; tools which have revolutionized acoustic technique.
The word technique is apparently being used as a mass noun, though my intuition is that in today’s American English such a usage is not common. Would someone care to discuss on the mass/noun status of this noun in different dialects of English during different time periods, or provide a general discussion of historical changes between mass/count status?
I have made no effort to consult readily available reference works in order to answer my question before posting here.
