Landmark book by Thomas Kuhn, published in 1962, describing a new way to look at science. Previous attempts to rationalize science (e.g. by Karl Popper) portrayed science as a neverending sequence of hypotheses trials, ignoring the social consequences of humans doing science. Kuhn recognized that as social creatures, humans were not frictionless science machines willing to drop a life's work to embrace new truths. He divided science into periods of normal science (e.g. figuring out the tenth digit of some constant) followed by revolutionary science (where new ideas are vigorously debated and later accepted). Kuhn coined the phrase Paradigm Shift to describe the adoption of a new scientific theory.
