On Exactitude in Science is an ongoing project that began as a modest investigation into the history of aviation. For these installations, I cover the nose of paper airplanes in graphite and throw them at the wall. Wherever they hit, I drill a hole and insert a marking flag.

Marking flags are tools for surveying and mapping, but here their placement is determined according to the arbitrary flight patterns of paper airplanes. While the final composition gives the appearance of scientific precision, it is actually generated by chance.

The project's title is taken from a short story of the same name by Argentine writer Jorge Luis Borges.
