Scientists at the University of Waterloo have determined the optimal design for a splash-free urinal: a tall, slender porcelain structure with curves reminiscent of a nautilus shell, playfully ...

The designs are highlighted in a study published ... a urinal that produce spiraling similar to the geometry seen in nautilus shells (hence one of the new urinal names). From there, the study ...

Pan and colleagues’ design — a tall, narrow urinal with a curving inner surface — employs the same geometry as a nautilus shell (SN: 4/1/05). “There’s a smooth flow across the surface ...

In 3D, the shapes can be found in nautilus shell segments ... it appears that humans have intuitively understood soft cell designs for years—architectural designs such as the Heydar Aliyev ...

The optical rotatum's logarithmic spiral follows a pattern often found in nature, including nautilus shells. (Image Credit: Capasso Lab / Harvard SEAS) Patterns exist all around the world, creating ...
