Summary in English

This is a scientific essay. The process of scientific discovery often involves formulating hypotheses, testing predictions, and an interdisciplinary search in the real world. A scientific inquiry carries on several assumptions and testing to get the invention of scientific discovery. Thus, the writer tries to say that one should formulate a good hypothesis, test the possible conditions and reach the conclusion through a rigorous scientific inquiry.
Hempel talks about the research of Ignaz Semmelweis who discovers the main cause of the death of a large number of women who believed babies in the First Division. Semmelweis, a physician of Hungarian birth, did this work during the years from 1844 to 1848 at the Vienna General Hospital. As a member of the medical staff first Maternity Division in the hospital., he was distressed to find that a large proportion of the women who were delivered of their babies in that division contracted a serious and often fatal illness known as perpetual fever or childhood fever. They died from it while they delivered their babies.
Semmelweis began by considering various explanations that were current at the time. He chose some for the experiments. One of the views assumed that the cause was epidemic influences. However, he argued that such influence could not affect the First Division only. In both the First and Second Division, women delivered babies suffered from childbed fever and died of it. But the surprising thing was that the number of women who died of such fatal illness was greater in the first Division. But the crowd was more in the Second Division because the patients wanted to avoid the notorious First Division.
Semmelweis formulated his hypothesis by rejecting some meaningless or confused explanation. He adopted some logical predictions as follows:
He knew that epidemic influence was one of the causes but did not know why it was fatal in the First Division.
Overcrowd might be another cause but the crowd was more in the Second Division.
Another cause might be that the trainees were doing rough experiments and causing injuries. However, the death rate in the First Division was the same even after decreasing such number of medical students.
Finally, the research of Semmelweis reached to the significant conclusion that the women in the First Division died due to blood poisoning. The doctors and medical students used to come to the First Division from the autopsy room without washing their hands properly, and they used to examine the women who delivered babies. Therefore, when the doctors and trainees washed their hands properly and examined the women, the mortality rate in the First Division got decreased. Similarly, the midwives examining patients in the Second Division required no autopsy training. Thus, the death rate among the women they examined was low in the Second Division. Similarly, infected mothers transmitted the infection to their babies as well.
