"New 14-Sided Shape Sheds Light on Natural Order"
A retired print technician from England discovered a 13-sided polygon called "the hat" that can completely cover an infinitely large flat surface without ever repeating the same pattern, making it the first "einstein" and solving a problem posed 60 years ago. The mathematician then discovered a new shape called "the spectre," which requires no mirror image, making it an even purer einstein. Both shapes are "stunning" and may lead to a deeper understanding of order in nature.
