中国著名核物理学家、纳米专 家、半导体专家等科技界权威人士今天聚会,纪念100年前创立、对本世纪经 济、科技、军事和社会进程产生重大影响的量子论。 应用量子论,参与研制中国第一颗原子弹的物理学家、中国科学协会主席 周光召在纪念大会上说,量子论和量子力学对人类社会的科学、哲学、技术和 经济带来了巨大的影响

能带理论是目前研究固体中电子运动的一个主要理论基础在二十世纪二十年代末和三十年代初期, 在量子力学运动规律确立以后,它是在用量子力学研究金属电导理论的过程中开始发展起来的.最 初的成就在于定性地阐明了晶体中电子运动的普遍性的特点

That streams of electrons possess the properties of beams of waves was dis- covered early in 1927 in a large industrial laboratory in the midst of a great city, and in a small university laboratory overlooking a cold and desolate sea. The coincidence seems the more striking when one remembers that facil- ities for making this discovery had been in constant use in laboratories throughout the world for more than a quarter of a century. And yet the coincidence was not, in fact, in any way remarkable. Discoveries in physics are made when the time for making them is ripe, and not before; the stage is set, the time is ripe, and the event occurs-more often than not at widely separated places at almost the same moment

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
