Early in the essay, Kuhn gives some basic description of the scientific method.
Science involves paradigms, puzzles, anomalies, discoveries and revolutions.
Before one goes about experimentation in attempt to make some astounding discovery, he must have some paradigm theory which sets the background for which his ideas are to be based upon. This paradigm theory is provided to the scientist through his education which is obtained through the knowledge of other persons of the profession who have their own certain beliefs and attitudes about established paradigms and previous revolutions. The scientist also obtains his knowledge throughout the course of his education from textbooks which contain the theoretical and generally accepted as factual findings of other scientists throughout history. Given a paradigm theory, the next step is to define a problem with a guaranteed solution to pursue. There are three classes into which scientific problems fall into.
