<br/><br/> Discusses how scientists try to establish a theory, what happens when a theory is established, how "normal science" takes an existing theory as truth and tries to prove it, and how research must often be conducted without a guiding theory.  Illustrates this by the work of Dr. Semmelweis on puerperal fever and Dr. Koch on anthrax and how the connection between microorganisms and disease was explained.
