Application of these, often defined by certain methodology, are frequently classified into areas of knowledge. Therefore it is natural for one to see similarities and differences within the process of attaining knowledge in different areas of knowledge. When the method forming scientific and historical models for human understanding of the world are examined, many similarities can be seen. These differences and similarities can also be seen when products of explanations are assessed. When scientific and historical explanations are compared one can see many similarities.
Empirical evidence are used in both scientific and historical explanations. For example, scientists have found a viable model of Deoxyribonucleic Acid (DNA) replication through empirical evidence. In
1958, Matthew Meselsohn and Franklin Stahl devised and executed an experiment to study DNA replication1. They attached two isotopes of nitrogen to each strand of DNA to determine what proportions of the isotope were present in DNA strands after multiple replication process. They observed that after one replication of DNA, each new molecule of DNA possessed one strand with the heavy isotopes of nitrogen. This evidence showed that the replication of DNA is semiconservative – the idea of copying via template2. The use of empirical evidence helped to explain the DNA replication process, even though one could not see the actual strands of DNA replicating. Looking at historical explanations one can see similar applications of empirical evidence. For example, historians such as
John Lewis Gaddis came up with theories about the cold war. From observing policies of the United
States and the Soviet Union, Gaddis have formulated theories about spheres of influences, and how these spheres of influences led to rising tension between the two super powers and eventually to the cold war. One may conclude that this
