WebMany structures in nature look symmetric, but this is not completely accurate, because absolute symmetry is close to death. Chirality (handedness) is one form of living asymmetry.

Pasteur's discovery of the connection between optical activity and molecular chirality led him to suppose that the forces of nature are not mirror-symmetric. His conjecture is supported by the recent discovery that the weak interaction between fundamental particles does not conserve mirror-image equivalence, violating parity. the post companyWebJul 11, 2024 · Chirality relates to the study of the three-dimensional structure of molecules. The term comes from the Greek root kheir-, hand, and means "handedness." Chiral molecules show left and right-handed nature in the sense that the molecules may exist as mirror-image forms that cannot be made to overlap by any amount of rotation. siege of dragonspear viconia
