chiral1894

1894 Ld. Kelvin Boyle Lect. in Jrnl. Oxf. Univ. Jun. Sci. Club 25 May 25 (note) I call any geometrical figure, or group of points, chiral, and say that it has chirality, if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.

1939 Nature 11 Feb. 240/2 The tensor scheme of relativity is incomplete by itself to include relations of chirality, to use Lord Kelvin's term... This significance of the chiral property..is the difference between a chiral system and its mirror-image.

1957 Physical Rev. 106 1306/2 This leads to two alternative assignments of K particles to chiral eigenstates.
