Mathematically, such objects are described as exhibiting rotational symmetry, for being “invariant under rotation.” Such objects have a point (in 2-D) or an axis (in 3-D) about which an object ...

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

Xiaobei Zhang at Shanghai University (SHU), China, are interested in deformed Reuleaux-triangle resonator (RTR) which breaks rotational symmetry to simplify exceptional point achievement.

Rotational symmetry is where a shape or pattern can be rotated or turned around a point and it looks the same. Have a go at this crafty activity to create your own symmetrical fabric art with this ...
