Mody’s book concentrates on the mesoscale of organisations involved in developing microelectronics because he argues it helps us get a sense of how the semiconductor sector influenced scientific knowledge-making. He shifts fluidly between detail and contextual currents, capturing the coalescence of individuals and institutions into configurations. These groupings splinter, disband and regroup after massive or minute changes, like IBM’s foray into circuits involving superconducting materials, the drying up of funding sources or the exit of a key team leader.
