The same researchers behind the 13-sided "hat" shape have stumbled upon a version that improves upon the original in a very important way. Reading time 2 minutes In March, a group of mathematicians ...

Look carefully! Mathematicians have invented a new 13-sided shape that can be tiled infinitely without ever repeating a pattern. They call it "the einstein." For decades, mathematicians wondered if it ...

What has 14 sides, is full of curves, and can perfectly cover a surface with no gaps or overlaps? It's not a riddle — it's a "vampire einstein." In March, a retired printing technician named David ...
