1941—1942年,我在昆明国立西南联大物理系读四年级。该系规模很小,约有教职员十名、讲师十名、几个研究生和每一年级不足二十名的本科生。1941年秋季开学时,校园里出现了一张新面孔,他旁听大学四年级和研究生的许多课程并参加各种讨论。此人就是黄昆。在此之前,他已在北平燕京大学获得物理学学士学位,此来联大作讲师。不久我们便彼此熟识了,并从此建立了长达半个世纪之友情。当年,我们所学的课程中包括量子力学与经典力学,这两门课程由吴大猷教授执教。量子力学是物理学发展史上的一场革命,1925—1927年间始于德国、瑞士、英国和丹麦。吴教授,这位中国的物理学家,在本世纪30年代和40年代初培养了大批这一重要的新分支学科方面的
From 1941 to 1942, I was in fourth grade in Physics Department of Kunming National Southwest United University. The department is small in scale with about 10 faculty members, 10 lecturers, several graduate students and undergraduates of less than 20 in each grade. A new face appeared on campus during the fall of 1941, when he attended many of the fourth-year and post-graduate courses and took part in various discussions. This person is Huang Kun. Before that, he had a bachelor’s degree in physics from Yenching University, Peking University. We soon became acquainted with each other and established friendship for half a century. That year, we have learned the course of quantum mechanics and classical mechanics, these two courses taught by Professor Wu Dali. Quantum mechanics is a revolution in the history of physics. It started in 1925-1927 in Germany, Switzerland, the United Kingdom and Denmark. Professor Wu, a Chinese physicist, trained a large number of this important new branch of discipline in the 1930s and early 1940s
