Quasicrystals And Geometry -

They are used as coatings for non-stick frying pans and surgical tools.

In classical geometry, you can tile a flat surface perfectly using triangles, squares, or hexagons. However, you cannot tile a floor using only regular pentagons; gaps will always appear. Because of this, scientists believed crystals could only have 2-, 3-, 4-, or 6-fold rotational symmetry. Quasicrystals and Geometry

Quasicrystals are essentially the 3D physical manifestation of these non-repeating geometric patterns. 3. Higher-Dimensional Projections They are used as coatings for non-stick frying
