<Big science> is distinguished by the scale and organization needed to sustain a research system: expensive apparatus, teams with specialized roles, substantial institutional funding and long planning horizons. An accelerator laboratory makes the point concretely. Its beam source, magnets, vacuum system, detectors, computing and maintenance have to operate together before an individual physical measurement can be made. Discovery is distributed across theorists, experimentalists, engineers, technicians and administrators.
The change is not just a larger apparatus. Funding agencies and governments influence which long-term projects are feasible; collaborations need procedures for allocating beam time, sharing data and assigning credit. Research instruments can become shared facilities that outlive a single experiment. The physical question and the technological capability co-evolve: a new <energy> or precision range opens questions that could not previously be tested, while those questions justify new infrastructure.
Wartime mobilization and subsequent state support accelerated these arrangements, but large coordinated observatories, surveys and prewar laboratories show that it was not created from nothing in one year. Nor did every scientific field become organized identically. A small group can depend on a large facility, and an institutionally large program can still contain individual conceptual innovations.
The benefits include access to rare processes, reproducible high-quality data and technical resources beyond one investigator's reach. Costs include bureaucratic dependence, competition over large budgets, barriers to entry and the risk that expensive infrastructure directs the questions asked. The useful historical category identifies this changing relation between knowledge, technology and collective institutions; it is not a claim that scale itself guarantees better science.<Science, the Endless Frontier by Vannevar Bush>[1945, chapters 3–6 on research support, personnel and institutions]{ref}
