Exercise 13

As often happens in science, one observation or experiment that is used to look at one aspect or subdiscipline of science can lead to profound explanations or solutions in another aspect or discipline of science. Serendipity and experimental mistakes also play a role. Explain how this might apply to Angelina Hesse and the success of Robert Koch's pure cultures, Louis Pasteur's as sistant and the success of the immunizations of chickens against chicken cholera, plus Alexander Fleming and Penicillium.
