Of Symmetry and Tessellation (Nina Qiu)

Posted on Updated on

There are four types of symmetry mentioned: rotational
(point symmetry), reflectional (line symmetry), scale, and translational (tessellation)
symmetry. If you look closely into nature, you could find all kinds of
symmetry, especially tessellation.


Some examples include reptile scales, spider webs,
honeycombs, and pineapples. You can identify tessellation by looking at the
shapes that assembled together to form an object’s appearance, such as a snake’s
skin. You can see the fan shaped scales overlapping each other, thus translational.
It is quite amazing how nature has a way of forming mathematical patterns that
humans cannot fathom. It gives a certain aspect towards the question: whether
or not is math invented or discovered?
