Jon Wright reviews Charles W. J. Withers’s Zero Degrees: Geographies of the Prime Meridian (Harvard University Press, March 2017) for Geographical magazine. Zero Degrees is about the effort to establish a single, uniform prime meridian from among more than two dozen rival claims. As Wright writes, “Withers manages to turn what might have been an obscure, rather technical topic into a fascinating account of international rivalry and a meditation on what the whole business of measuring the world around us can reveal about broader cultural patterns.”
