Nobel lecture december 12, 1933 On passing through an optical instrument, such as a telescope or a camera lens, a ray of light is subjec reflecting surface. The path of the rays can be constructed if we know the two simple laws which govern the changes in direction: the law of refrac- tion which was discovered by Snellius a few hundred years ago, and the law of reflection with which Archimedes was familiar more than 2,000 years ago

我一生中最具革命性的思想 “根据这里的假设,当一束光从点光源发出时,它的能量不是随体积增大而连续分布, 而是包含一定数量的能量量子,这些能量量子在空间的局域存在,不随运动而分裂,并只作 为一个整体被吸收和发射

Nobel Lecture december 13. 1946 The history of the discovery of the exclusion principle m, for which I have received the honor of the Nobel Prize award in the year 1945, goes back to my students days in Munich. While, in school in Vienna, I had already ob- tained some knowledge of classical physics and the then new Einstein rel- ativity theory, it was at the University of Munich that I was introduced by Sommerfeld to the structure of the atom- somewhat strange from the point of view of classical physics. I was not spared the which every

整个科学的发展与全人类的文化是分不开的,在西方是这样,在中国也是如此。可是科 学的发展在西方与中国并不完全一样。在西方,尤其是如果把希腊文化也算作西方文化的话, 可以说,近代西方科学的发展和古希腊有更密切的联系。在古希腊时也和现代的想法基本相 似,即觉得要了解宇宙的构造,就要追问最后的元素是什么

The events leading to the discovery of tunnelling supercurrents took place while I was working as a research student at the Royal Society Mond Labo- ratory, Cambridge, under the supervision of Professor Brian Pippard. During my second year as a research student, in 1961-2, we were fortunate to have as a visitor to the laboratory Professor Phil Anderson, who has made numerous
