A geometry problem that has been puzzling scientists for 60 years has likely just been solved by an amateur mathematician with a newly discovered 13-sided shape. Called “The hat” because it vaguely ...

The “hat” wowed mathematicians. Now the shape is shaking up physics. In 2023, mathematicians reported that the 13-sided tile was the first known “einstein.” That’s a shape that can perfectly cover an ...

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 ...

MATHEMATICIANS have invented a new 13-sided shape that can be rearranged infinitely without repeating a pattern. For many decades, mathematicians tried to find a shape that they could retile perfectly ...
