## Chiral Symmetry

"Chiral" comes from the Greek for "Hand". The most straightforward example of Chiral symmetry is the mirror symmetry shown by your left and right hand. Chirality is a concept of importance in several areas of science.

### Famous quotes containing the word symmetry:

“What makes a regiment of soldiers a more noble object of view than the same mass of mob? Their arms, their dresses, their banners, and the art and artificial *symmetry* of their position and movements.”

—George Gordon Noel Byron (1788–1824)
