It was hosted by Columbia University in New York City, March 2017. The theme of the conference, Powers of Ten, is a reference to a short film from 1977 by Charles and Ray Eames. Like the film, Architectural Paint Research (APR) deals with magnitudes of scale, from a single pigment particle, to a painted house, to the decorative tastes of an entire region. In the spirit of the film, the 2017 APR conference took a closer look at how we carry out our research at every level, from the micro to the macroscopic.
