What a Physics Student Can Teach Us About How Visitors Walk Through a Museum


What happens when we walk through a museum? In a class I’m teaching on American art in the age of George Washington and Thomas Jefferson, this question came up. As a speculative exercise, we are designing an exhibition that involves trying to lay out a group of varied objects—including some that require close attention, such as architectural drawings—in a pathway that will make sense to visitors of different ages and levels of art experience.

To devise a good layout requires some understanding of what museum visitors do, and there’s surprisingly little literature on this topic. Most of the studies of museum-goers that I’ve seen rely on questionnaires. They ask people what they did, what they learned, and what they liked and didn’t like. No doubt there are virtues to this technique, but it assumes that people are aware of what they’re doing. It doesn’t take into account how much looking depends on parts of the brain that are largely instinctive and intuitive and often not easily accessible to our rational consciousness. Was there another mode of investigation and description that would illuminate what was actually taking place?

One of the students in my class, Andrew Oriani, is a physicist who spends much of his time doing mathematical proofs consisting of six or seven pages of equations. (He also has notable visual gifts: as a child he liked to draw elaborate cross-sections of ocean liners). He immediately grasped that the question we were asking was similar to one that comes up in physics all the time. How can one describe the activity of a group of subatomic particles that are moving unpredictably, seemingly erratically, in space? In physics this has become a subdiscipline known as statistical mechanics, and physicists have devised sophisticated tools, such as heat mapping, to describe how particles move in time and where they collect. In essence, physicists have found ways to describe and analyze events that are not specifically predictable, but that, when they’re repeated over and over again, turn out to obey recognizable principles. What would we find, Andrew asked, if we simply mapped the movements of visitors through a museum? What kinds of patterns would we find if we gathered enough data? Could we discern a recognizable pattern that had a shape? What would these patterns of movement reveal about the act of looking?

The preliminary results of asking these questions are provided by the three diagrams in this post. Perhaps there are studies of this sort that have already been published, but I haven’t come across them. Admittedly, Andrew’s diagrams are not precisely accurate—he worked freehand, without exact measurements—but for that very reason they have a wonderfully expressive quality: I must confess that part of what appeals to me about them is simply their beauty as drawings. Even without knowing what they’re about, we can sense that they contain information and they record something mysterious and interesting. In fact, what they record is not difficult to explain.
