https://doi.org/10.1007/978-3-319-91331-5tics, and especially the implied geometry, was sometimes implicit. Folding a piece of paper—so it may seem—did not have a place in this new (doubled) geometrical order, even if this piece of paper were folded into a geometrical form, e.g., a polyhedron.领巾 发表于 2025-3-23 23:42:49
