Although all knowledge has its profound values and uses, it is notable that some knowledge categorized into certain fields of study has less or more significant reliability than the others. The reason lies heavily in the method and tools that the knowers use to cultivate knowledge in the field. The areas that use methods that eliminate the possibility of variation regarding various factors that impact the creation of knowledge have more evident knowledge.
Natural science use tools such as experimental design, modeling, data analysis, and more to falsify or clarify the hypothesis. Because these methods generally do not consider the unpredictable character that humanity bears, this type of investigation refers to the method that is most reliable to the human to make real-life application and decisions. In 1895, Wilhelm Roentgen accidentally discovered the X-ray while testing with other rays if they could pass through the glass. Before the invention of X-ray, broken bones, tumors, and the location of bullets were only determined and medicated by the physical examination and a doctor’s best guess. Even worst, in the cultural area of Asia, people depended on superstition, believing that serious diseases are a punishment from God. The invention of X-rays allowed doctors to see inside the human body without surgery. Therefore, having a more concise magnifier into the patient body allowing the detection of diagnosing, monitor, and other many medical conditions.
In fact, after the first war, hospitals became heavily dependent on X-ray machines, having a significantly large increase in survival rate. In modern lives, X-rays are essential. In 2018, 18.1 million new cases and 9.5 mission cancer-related deaths occurred. As cancer is the leading cause of death worldwide, the detection of the tumor by x-ray has unmeasurable value in its function.
In conclusion, the case of x-ray has shown us that the scientific observation that X-ray provides has worked more efficiently than other methods that were conducted under the characteristic of humans evidenced by the increased rate of survival rate, showing the reliability of scientific observation. Therefore, on the extent involving the need for scientific observation such as investigating the structure of the body, scientific knowledge is more reliable than any other field of knowledge.
