在过去的50多年里,人类社会发生了巨大的变革,以计算机为代表的信息革命深入到了我们生活的每一个角落。人们不禁要问:是什么科学技术在幕后推动着这场变革呢?信息时代的各种创新能够得以实现,都基于电脑和互联网的存在,而电脑技术能够突飞猛进,完全要归功于人类对微观世界认识的深入。微观世界,简单说来就是原子和电子的世界。理解微观世界,我们就得求助于20世纪最重要的科学理论——量子理论。
In the past 50 years or so, great changes have taken place in human society. The information revolution represented by computers goes deep into every corner of our lives. People can not but ask: What science and technology are behind the scenes to promote this change? Innovative information age can be achieved, are based on the presence of computers and the Internet, and computer technology can be by leaps and bounds, thanks to human understanding of the micro-world In-depth. Micro-world, in short, is the world of atoms and electronics. To understand the micro-world, we have to turn to the most important scientific theory of the 20th century-quantum theory.
