2.3.2. emphasizes revolutionary character of science

2.3.3. cycle pre-science normal science people believe in the paradigms they are working with mature science single paradigm which is precisely defined crisis scientists have doubts about scientific paradigms can be caused by anomalies gestalt switch takes place all of a sudden, not transient revolution
