They say that no two snowflakes are the same, but like all natural ice crystals they are only variations on the same six-sided theme. Now physicists have found the first evidence of pentagonal ice ...

Two years ago the mathematical world was abuzz about the discovery of a 15th tiling of the plane by convex pentagons (I wrote about it here). Still the question remains: are these the only ones or are ...

A team of UK researchers has grown ice crystals in which the water molecules are arranged into pentagons rather than the hexagons found in every natural snowflake. The unusual ice was grown on a ...
