tiling of the pentagon
how about this? marjorie rice, who never went to college, discovered four types of tessellating pentagons not previously known to mathematics.
and that that fascinating quasicrystalline pattern, not recognized as occurring in nature until 1984 (and taking years to be accepted), appears in persian mosaics from the 15th century.
oh, and, no kidding, the song bythos shuffled to while i was reading about this stuff & directly before miracles, was crystal by new order.
