To begin to understand what mathematicians and physicists see in the abstract structures of symmetries, let’s start with a familiar shape. We are fond of saying things are symmetric, but what does ...

We are fond of saying things are symmetric, but what does that really mean? Intuitively we have a sense of symmetry as a kind of mirroring. Suppose we draw a vertical line through the middle of a ...

Symmetry attracts us. Studies comparing people’s reactions to different faces have shown, for example, that they find highly symmetrical faces more attractive than less symmetrical faces. The symmetry ...

The human visual system excels in interpreting complex visual scenes, with symmetry perception playing a pivotal role in organising sensory input into coherent representations. Visual symmetry ...

Chirality can be true or false, depending on the symmetry of dynamic propagation. Crystal lattice vibrations, called phonons, can also display chirality as has been shown in some two-dimensional ...
