Displacement: Applying a Physics Perspective to a Literary Concept

You guys are going to have to forgive me: I may be an English Writing Major, but I am also a Chem/Math double minor, so I do have a tendency to sometimes think about abstract or literary concepts in a "scientific" manner. When we started our brainstorming of the term "displacement" in class on Thursday, the scientist in me immediately jumped to the physics definition, which refers to "how far out of place an object is." I know, I know, you are probably all uttering something along the lines of "ummm...duh?!" I realize this definition of the word is pretty much explicitly implied in the word itself: DIS-PLACE-ment; but I think there is more to the definition than what appears on the surface. I started explaining my interpretation in class as taking this to mean a kind of journey, as in how one might actually get from her starting point to her destination. After class, I realized that I had the concepts of "displacement" and "distance" flip-flopped (thank God I decided to go with the English thing, right?), and the difference between the two in physics is actually what allows the scientific definition to be applied for our purposes. So, for a clarification, check out

This is a groovy little tutorial that does a really good job explaining the difference between "distance" and "displacement." And NOW, for my probably over-reaching and annoyingly lengthy interpretation:

I think it's important to note that distance refers to "how much ground an object has covered," whereas displacement refers to where the object actually is in relation to where it began. So, technically, an object (or a person, for our purposes) may travel a great distance, undergo a long, hard, and complex journey, and still find itself right back where it started. I like this idea of displacement being independent of a person's ventures in life. It suggests that we can make mistakes and have regrets but still ultimately have a sense of and be able to return to where we started and where we belong. The only way we can truly be "displaced" is if we venture out, lose our way, and don't find a path that takes us back to where we started; in essence, if we "lose ourselves completely." Also, the website says that displacement is "the object's overall change in position," which we can apply in both a literal and figurative sense. A person may find herself diplaced if her physical location changes, but also if her political, religous, or any other personal belief ("position") changes. For example, I believe that Othello finds himself "diplaced" when his position regarding human nature changes. Iago originally portrays Othello to be of a generally optimistic and trusting nature, saying that "[t]he Moor is of a free and open, nature,/That thinks men honest that but seem to be so" (lines 382-83). Iago then notes a change (a "displacement") in Othello after he as planted the seed of jealousy in his mind: "The Moor already changes with my posion" (line 342). Invoking the physics definition, we interpret Othello's "position" regarding human nature to have undergone an "overall change," i.e., jealously has caused him to lose his generally trusting nature, and we thus consider him "displaced."
