Mathematicians discovered a shape that can cover a surface without a repeating pattern after 50 years of searching.
This shape, known as a nonperiodic tiling, cannot be copied and laid perfectly onto itself.
Aperiodic tiles, which cannot create repeating patterns, were first found in 1964, with the number decreasing to just two by Roger Penrose.
In March of this year, a retired printing technician named David Smith discovered the Ein Stein Tile, made up of eight kite shapes.
Smith contacted Craig Kaplan, a computer scientist, who confirmed the potential significance of the tile.
The tile was named the hat after discussions on its appearance, and a mathematical proof was needed to confirm its aperiodicity.
A team of mathematicians and a software engineer collaborated to prove the hat's unique hierarchy, ensuring non-periodicity.
Dave discovered another aperiodic monotile, the turtle, which could morph into the hat, leading to an infinite continuum of aperiodic tiles.
The discovery of multiple aperiodic monotiles caused celebration in the mathematics community.
Despite some criticism that the tiles were not truly aperiodic due to reflections, Dave found a single tile that tiled aperiodically without its mirror reflection.

The Einstein Tile, known as the spectre, was created as a tribute to the creator's deceased brother, symbolizing a spirit or presence watching over them.
Aperiodic patterns, like the Einstein Tile, are not only visually appealing for bathroom floors but also hold practical applications in material science, showing promising properties such as increased elasticity and resistance to failure compared to periodic lattice materials.
