How did Bridgman influence modern physics?
My operationalist approach had a profound impact on how physicists think about fundamental concepts. When Einstein developed special relativity, he implicitly used operational definitions—for example, defining simultaneity by light signals and synchronized clocks. I made this method explicit and argued that it should be applied universally. In quantum mechanics, the uncertainty principle forced us to recognize that the operations of measurement are inseparable from the properties we measure. My work in *The Nature of Physical Theory* (1936) emphasized that science is what scientists do, not a set of eternal truths. This influenced later thinkers like P. W. Anderson and even aspects of the philosophy of quantum information. However, I must stress that operationalism is a tool, not a dogma—it must be applied with care to avoid reducing all science to mere procedure.
