Big Science is a term used by scientists and historians of science to describe the change in science which occurred in industrial nations during and after World War II.
While World War I was the first war in which science played a major role in warfare and armaments, the increase in government and industial patronage for science following the second World War was on a scale wholly unprecedented. World War II has often been called "the physicists' war" for the role that those scientists played in the development of new weapons and tools, notably the proximity fuse, radar, and the atomic bomb. The bulk of these last two activities took place in a new form of research facility: the government-sponsored laboratory, employing thousands of technicians and scientists, managed by universities (in this case, the University of California and the Massachusetts Institute of Technology).
In the shadow of the first atomic weapons, the importance of a strong scientific research establishment was apparent to any country wishing to have a role in international politics. After the success of the Manhattan Project -- a scientific and technological endeavor on an unprecedented scale -- international governments became the chief patron of science, and the character of the scientific establishment underwent several key changes.
"Big Science" usually implies, and gets its "big-ness" from, these specific characteristics:
- Big budgets: No longer required to rely on philanthropy or industry, scientists were able to use budgets on an unprecedented scale for basic research.
- Big staffs: Similarly, the number of practitioners of science on any one project grew as well, creating difficulty, and often controversy, in the assignment of credit for scientific discoveries (the Nobel Prize system, for example, allows awarding only three individuals in any one topic per year, based on a 19th-century model of the scientific enterprise).
- Big machines: Ernest Lawrence's cyclotron at his Radiation Laboratory in particular ushered in an era of massive machines (requiring massive staffs and budgets) as the tools of basic scientific research.
- Big laboratories: Because of the increase in cost to do basic science (with the increase of large machines), centralization of scientific research in large laboratories (such as Lawrence Berkeley National Laboratory or CERN) has become a cost-effective strategy, though questions over facility access have become prevalent.
It has also been stated as involving five Ms: Men, Machines, Media, Money, and Military.
Towards the end of the 20th century, the amount of industrial patronage of basic scientific research has grown as well, especially in the fields of bioengineering and robotics. The heavy investment of government and industrial interests into academic science has also blurred the line between public and private research, where entire academic departments, even at public universities, are often financed by private companies.
The era of Big Science has provoked criticism that it undermines the basic principles of the scientific method. Results of experiments which require massive and unique machines like particle accelerators are often difficult to verify. Access to scientific facilities is often limited to those who are already accomplished, leading to charges of elitism. And increased government funding has often meant increased military funding -- which some claim subverts the Enlightenment-era ideal of science as a pure quest for knowledge. Many scientists also complain that the requirement for increased funding makes a large part of the scientific activity filling out grant requests and other budgetary bureaucratic activity, and the intense connections between academic, governmental, and industrial interests have raised the question of whether scientists can be completely objective when their research contradicts the interests and intentions of their benefactors.
Big Science was also the title of a 1982 album by performance artist Laurie Anderson.
