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.
