Percy Bridgman
American physicist (1882–1961), Harvard professor, Nobel laureate, and founder of operationalism — the doctrine that a concept is defined by the set of operations used to measure it.
Percy Williams Bridgman was an American experimental physicist who spent his career at Harvard University and won the 1946 Nobel Prize in Physics for his work on the physics of extremely high pressures, developing apparatus and techniques that opened a new field of matter under compression. Beyond the laboratory he is remembered as a philosopher of science: in The Logic of Modern Physics (1927) he argued that the meaning of a scientific concept lies in the concrete operations by which it is measured, a position that came to be called operationalism (or the operational definition) and that shaped mid-century thinking about how physics grounds its terms in observable procedure.
Relationship to Fuller
Relationship: influence-on-fuller. In Omnidirectional Halo, R. Buckminster Fuller recounts arriving intuitively at the rule that any answer to "What do you mean by the word 'universe'?" must be drawn exclusively from human experience — and notes that "many years later" he learned "the Nobel physicist Percival Bridgeman had identified this same rule adopted by Einstein as 'operational procedure.'" Fuller thus enlisted Bridgman's operationalism as the epistemological warrant for his own experiential definition of Universe as "the aggregate of all consciously apprehended and communicated experience of man." The affinity places Bridgman alongside the language-critical and experience-grounded thinkers Fuller drew on — a strand shared with Alfred Korzybski — and Fuller explicitly ties the operational stance to Albert Einstein, from whom he says Bridgman drew the example.
