A Pollock, in the Eyes of Art and Science

Two related articles about a recent scientific analysis done on a set of recently discovered paintings attributed to Jackson Pollock. However, the analysis raised question about the attribution, which in turn is not accepted by the art historian who had put forward the attribution.

This points to a fundamental difference in terms of approach:

"In the wider art world, traditional scholarship is beginning to accommodate science a little more willingly. But some experts say the friction between the two is not only about turf wars but also about fundamental differences in culture [...] [P]art of the problem was that “art historians basically do not collaborate” while science demands it."
