The 70th Anniversary of the Discovery of Parity Non-conservation and Frontier Physics Conference will be held in Kunming from October 15 to 17, 2026.

The year 2026 marks the centenary of Mr. Tsung-Dao Lee's birth and the 80th anniversary of the National Southwestern Associated University's demobilization and return north. Seventy years ago, Mr. Tsung-Dao Lee and Mr. Chen-Ning Yang proposed the theory of parity nonconservation, a groundbreaking achievement for which they were awarded the Nobel Prize in Physics in 1957. 

The conference is co-hosted by the Kunming New Quality Productive Forces Promotion Center, the Tsung-Dao Lee Institute of Shanghai Jiao Tong University, the Chen-Ning Yang Institute for Advanced Study of Tsinghua University, Yunnan Normal University, and the Shanghai Future Qidian Community, and is co-organized by the Tsung-Dao Lee Center for Sciences and Arts together with relevant Kunming municipal entities.

The conference aims to uphold the scientific spirit of truth-seeking and pragmatism, deepen Shanghai–Yunnan sci-tech collaboration, and empower the development of the Kunming International Complex Science Center.

2026年10月15-17日，宇称不守恒定律发现70周年暨前沿物理会议将在昆明盛大启幕。

2026年恰逢李政道先生百年诞辰、西南联大复员北返80周年。70年前，杨振宁、李政道两位先生提出宇称不守恒理论，并于次年荣获诺贝尔物理学奖，成为华人科学家首次屹立于世界物理学最前沿的标志性事件。

本次会议由昆明市新质生产力促进中心、上海交通大学李政道研究所、清华大学杨振宁高等研究院、云南师范大学、上海未来启点社区联合主办，李政道科学艺术中心与昆明市相关单位联合承办。本次大会旨在传承求真务实的科学精神，深化沪滇科技协同，赋能昆明国际复杂科学中心建设。
