杨振宁从小喜爱物理,而且想成为一个实验物理学家。1943年杨振宁赴美国留学时,就立志要写一篇实验物理论文。1946年,杨振宁进入芝加哥大学费米主持的研究生班,希望能在费米的指导下写篇实验论文。当时,费米正忙于在阿贡国家实验室从事军事技术研究,像杨振宁这样初到美国的中国人,不能随便进入阿贡实 Yang Zhenning loved physics since childhood and wanted to be an experimental physicist. When Yang Zhenning went to study in the United States in 1943, he decided to write an experimental physics paper. In 1946, Yang Zhenning entered the postgraduate class hosted by Fermi at the University of Chicago and hoped to write an experimental paper under Fermi’s guidance. At the time, Fermi was busy researching military technology at the Argonne National Laboratory. Chinese like Yang Chenning who first arrived in the United States could not enter Argoshi practically.
