American - Physicist | October 1, 1922 -
The existence of symmetry laws is in full accordance with our daily experience. The simplest of these symmetries, the isotropy and homogeneity of space, are concepts that date back to the early history of human thought.

I should like to say that I am as proud of my Chinese heritage and background as I am devoted to modern science, a part of human civilization of Western origin, to which I have dedicated and I shall continue to dedicate my work.

In the final analysis, the incident is seen as originating from an emotional expression of the frustration and anger of the proud people of China who had been subject to ever increasing oppression from without and decadent corruption from within.

The law of right-left symmetry was used in classical physics but was not of any great practical importance there. One reason for this derives from the fact that right-left symmetry is a discrete symmetry, unlike rotational symmetry, which is continuous.

The strongest interactions are the nuclear interactions, which include the forces that bind nuclei together and the interaction between the nuclei and the z mesons. It also includes the interactions that give rise to the observed strange-particle production.

The three discrete invariances - reflection invariance, charge conjugation invariance, and time reversal invariance - are connected by an important theorem called the CPT theorem.
