Big Science, style of scientific research developed during and afterWorld War II that defined the organization and character of much research inphysics andastronomy and later in the biological sciences. Big Science ischaracterized by large-scale instruments and facilities, supported by funding from government or international agencies, in which research is conducted by teams or groups of scientists and technicians. Some of the best-known Big Science projects include thehigh-energy physics facilityCERN, theHubble Space Telescope, and theApollo program.

The termBig Science first appeared in a 1961 article inScience magazine, titled “Impact of Large-Scale Science on the United States,” by physicist and Oak Ridge National Laboratory directorAlvin Weinberg. The article described Big Science as part of the newpolitical economy of science produced by World War II, during which the U.S. government sponsored gigantic research efforts such as theManhattan Project, the Americanatomic bomb program, and the Radiation Laboratory, a centre forradar research at theMassachusetts Institute of Technology (MIT). Weinberg was not only describing a new form of scientific research; his concept was an expression ofnostalgia for“Little Science,” a world of independent, individual researchers free to work alone or with graduate students on problems of their own choosing. Whether or not the world of Little Science as imagined by Weinberg ever existed became irrelevant; high-technologywarfare had turned support of scientific research into a national security priority and promised to turn scientists and engineers into beneficiaries ofCold War largesse.

Big Science shared many characteristics of other industrial and government enterprises. Large scale, expensive, and heavilybureaucratic, Big Science’s most ambitious projects—satellites and space probes, particle accelerators, and telescopes—rivaled those of military and industrial institutions in their size and complexity. Weinberg argued that they were the contemporary equivalents of Egyptian pyramids or Gothic cathedrals. Indeed, some countries founded entire cities—such as the United States’Oak Ridge, Japan’sTsukuba Academic City, and theSoviet Union’sAkademgorodok—to support scientific research. For researchers, the advent of Big Science signaled a transformation of the scientist from an independent researcher into a member of a hierarchically organized group. Scientists at facilities such asCERN found themselves working on projects that brought together hundreds of scientists, engineers, technicians, and administrators. This bureaucraticculture in turn reshaped scientific careers by making it possible to succeed through administrative skill, fund-raising ability, and managerial talent, as well as scientific brilliance. It also joined the trend inhigher education to emphasize research over teaching for scientists at research universities. The high cost of scientific instruments, facilities, and payrolls made Big Science affordable only to government agencies or internationalconsortia, drawing influence away from the universities, societies, and philanthropies that had been the main supporters of scientific research before World War II.

The products of Big Science also differed from those of preceding forms of scientific research. The literary results of Big Science were articles “written” by dozens or even hundreds of coauthors, rather than individuals or a few collaborators. As important as the published reports are the machine-readable archives of data generated by projects, which can be used by researchers long after the instruments that produced them are rendered obsolete.

With the end of the Cold War, the fortunes and complexion of Big Science began to change. The phenomenon had never been without its critics: its impact on science education was mixed, and during the 1960s American students at a number of campuses protested military-sponsored research conducted at Big Science facilities such as Charles Stark Draper’s Instrumentation Laboratory at MIT. The withdrawal of funding for the Superconducting Super Collider in 1993 marked the U.S. government’s retreat from its formerly lavish sponsorship of high-energy physics. The development at theNational Aeronautics and Space Administration (NASA) of smaller, lower-cost satellites in the 1990s was likewise motivated by demands to conduct research on a more economical scale. At the same time, Big Science began to spread to the biomedicaldisciplines via theHuman Genome Project. However, in that project, work was decentralized among a number of research sites, rather than concentrated in a single large facility. Further, its goal was not a set of research papers but the production of an archive, the sequence of thehuman genome. Finally, the project was supported in part by private firms hoping to use the archive in their own efforts to develop new pharmaceuticals and other medical products.
