A "paradigm shift" refers to a fundamental change in the underlying assumptions or practices within a particular field or discipline. This concept often occurs when new ideas or technologies challenge the existing norms, leading to a significant transformation in how people think or operate. For example, the introduction of the internet caused a paradigm shift in communication and information sharing. Such shifts can be seen in various areas, including science, business, and culture. A notable example is the transition from Newtonian physics to Einstein's theory of relativity, which altered the understanding of space and time. These changes can reshape industries, influence societal values, and drive innovation.
