For centuries scientists and historians alike have debated topics within their field of study. Whether it be the structure of an atom or the cause of the fall of the Roman Empire, experts in these fields often disagree despite having access to the same exact facts and information. These separate interpretations of data leads to the question of how it is possible that the same facts do not always point to the same general truths. Although experts in the fields of science and history have access to the same facts, the experts who analyze and interpret these facts are human beings, whose thoughts are impacted by the different cultures, experiences, and perspectives in which they were raised.One important question that needs to be raised is what makes someone an expert? Better yet, what is a fact? An expert is someone who has an extensive background in a certain subject and is recognized by others as having a comprehensive understanding of a specific topic. This means that they have a great understanding of the subject matter of which they are an expert, and others can attest to this proficiency. Facts are known truths that are commonly accepted and verifiable. A fact must be verifiable in order to be legitimate. Understanding these terms allows us to truly understand the nature of historians and scientists and their interpretations of information.
