This is the case for many scientific processes such as drawing molecules and describing natural phenomena (Reeves 27). Metaphors can sometimes become theories as well. According to Reeves, scientific theories created by scientists often start as metaphors that were chosen to help explain their ideas. A very famous example of a model beginning as a metaphor is the plum pudding metaphor (Reeves 29). The plum pudding metaphor was proposed by J.J. Thomson and it helped explain the distribution of negative and positive charges in an atom to those who had no background in science (Reeves 29). Obviously, the distribution of atoms is not really plum pudding, but the common person knew what plum pudding was, so it was an effective metaphor to use to describe such a complex process. This is an example of scientists using a metaphor to explain a complex process to non-scientists. It helped the common person understand the process by relating it to something they knew
