Nobel laureate Yang Chen-ning dies at 103

Chinese physicist Yang Chen-ning has died in Beijing at the age of 103 after an illness. Yang became a Nobel laureate in 1957. In 1956, Yang and another physicist, Lee Tsung-Dao, formulated a theory that the law of symmetry does not apply to weak interaction, meaning that mirror-image versions of events can be different.

The discovery won the Nobel Prize in 1957, as Yang and Lee became the first Chinese Nobel winners. Apart from his international scientific contribution, Yang promoted academic exchange between China and the U.S. He raised funds to sponsor almost a hundred Chinese scholars for further studies in America.
