A yin-yang symbol and a pinwheel are examples of objects that exhibit rotational symmetry. Objects in 2-D have a center of symmetry; objects in 3-D have an axis of symmetry.

For example, the square also has rotational symmetry. Here we see the process of rotating a square counterclockwise about its center point (the intersection of its diagonals).

Courtesy of This shows examples of the seven families of symmetry groups with six-fold rotational symmetry. Andrew Kepert/Wikipedia Grossman is particularly intrigued with the symmetry group of ...

For example, the square also has rotational symmetry. Here we see the process of rotating a square counterclockwise about its center point (the intersection of its diagonals).

Rotational symmetry: The laws of physics don't change if we turn around. These symmetries are crucial for understanding science, especially physics.

In a review just published in Nature Materials, researchers take aim at the oldest principle in electronics: Ohm's law.

This kind of symmetry is called reflective symmetry. It's not just in butterfly wings that you can see reflective symmetry, have a look through the slideshow below to see some other examples.

Still others — such as "O" — have rotational symmetry, where no matter how many degrees you rotate it, its appearance is unchanged. These are some examples of symmetry that are easy to ...

For example, a heart shape has mirror symmetry: look at the right half in a mirror and it looks exactly like the left half. A snowflake has rotational symmetry because you can rotate it a one ...

The characteristics of a material are generally very dependent on its rotation symmetry. Graphite and diamond, for example, both consist of carbon atoms and differ solely in their crystal symmetry.

Symmetry is a prevalent feature of nature at all scales. For example, our naked eyes can easily identify symmetries in the bodily shape of countless organisms.
