This year’s Edge question is “What scientific idea is ready for retirement?” From mathematician Samuel Arbesman’s response:
While the trends clearly point to the advent of team science, small and clever science—the realm of the tiny budget or the elegant experiment, or sometimes even the hobbyist—is by no means over.
To be clear, small science is not necessarily the lone underdog working against the establishment. More often it is simply one or two underfunded scientists doing their best. But it seems that they can still survive even in this modern era of big science. For example, several years ago, a paleontology graduate student made a discovery that cleared a dinosaur of cannibalism charges that began with a very simple observation: by looking at one of the fossil casts on the wall of the American Museum of Natural History’s subway station. Or take the scientists who examined the space of possible ways to tie a necktie, and whose research was published in Nature. Little science is still possible. …
You can even still do science on the cheap. Several decades ago, Stanley Milgram measured the well-known Six Degrees of Separation using little more than postcards. While science has become bigger since then, in some ways it has become even easier to conduct large-scale science by the scientist who operates at a small scale: due to massive computational advances and widespread data freely available (not to mention easier data collection online), now any scientist can do big science cheaply and in a small and easy way. Technology has allowed research scientists to leverage a tiny budget in astonishing ways. And each of us can now even easily contribute to science as an amateur, through the growing prevalence of citizen science, where the general public can help—often in a small incremental way—to collect data or otherwise help with science. From categorizing galaxies and plankton to figuring out how proteins fold, everyone can now be a part of the scientific process.
