Cant Imagine Shapes in 4 Dimensions? Just Print Them Out
Last spring, mathematician Henry Segerman found a peculiar post on Facebook. It was by a programmer who had could not conjure mental images\u2014a condition called aphantasia. Segerman immediately recognized that he lives with the same limitation. \u201cWhen I try to visualize something, I don\u2019t see anything,\u201d he says. Which is curious\u2014because Segerman, 37, has made a career out of visualizing complex mathematical shapes.
