Many everyday objects have a property called chirality, or “handedness”, meaning that they look different when reflected in a mirror. For example, your right hand reflects into a left hand, and vice versa. WebAchiral (not chiral) objects are those objects that are identical to their mirror image. Chirality is commonly observed in nature and life, which exists at all length scales, from the molecular level (the single left- or right-handed amino acid) to the supramolecular level (the right-handed double helix of DNA), and up to macrobiomineralized ... clipstone youtube

"WebShort answer: In any number of dimensions, chiral objects come in pairs. This is because numbers come in pairs; positive and negative. You could say that numbers come in reciprocal pairs ( x and 1 x) as well, but the fact is, in the real world, only addition of coordinates has a meaning. " - Chiral objects
