In scientific usage, a theory does not mean an unsubstantiated guess or hunch, as it does in other contexts. Neither is a scientific theory a fact. Scientific theories are never proven to be true, but can be disproven. All scientific understanding takes the form of hypotheses, theories, or laws.

Examples include group theory, set theory, Lebesgue integration theory and field theory. The term "theory" also has a formal usage in mathematics, particularly in mathematical logic and model theory. A theory in this sense is a set of statements closed under certain rul ...

Although accepted as a medical treatment in Asia for millennia, acupuncture's arrival in the West has sparked much controversy. Acupuncture has eluded scientific explanation to some degree. However, in 1997, the NIH issued a consensus statement on acupuncture that concluded that there is sufficient evidence of acupuncture's value to expand its use into conventional medicine and to encourage further studies of its physiology and clinical value. The NIH statement noted that the data in support of acupuncture are as stron ...
