Summary

This video provides a brief, factual account of the groundbreaking work of Robin Warren and Barry Marshall and their discovery of the bacterial cause of peptic ulcer disease. Their story is a concrete example of the "Scientific Process" in practice. It illustrates that although the scientific method is often presented as a didactic list of steps, there is no one fixed sequence of events that occurs in order for important scientific discoveries to be made.
