杨振宁以“量子化、相,对称——20世纪物理学的旋律”为题首先介绍了20世纪人类在科学上的主要成就是,学会了控制电子的行动;发现了研究极小结构的方法;离开了地球引力实现了登月梦想。他认为近代科学的发展是以近代物理学的发展即伽俐略、牛顿的研究为先锋。那么20世纪物理学发展的动力是什么?是寻求对基本原理的深入了解,是基于对时间、空间、运动、能量、力量这些基本的自然的原始的了解。如果把20世纪前30年物理学的发展比作一部交响乐,则其中的三个主旋律是:1、量子化(1900年,
In the title of “Quantization, Phase and Symmetry - The Melody of Physics in the 20th Century”, Yang Zhenning first introduced that the major achievements of mankind in science in the 20th century were that they learned the action of controlling electrons and found that studying the minimal structure Method; left the Earth’s gravity to achieve the dream of going to the moon. He believes that the development of modern science is the development of modern physics that Galileo, Newton’s research as a pioneer. So what motivates the development of physics in the 20th century? It is to seek an in-depth understanding of the basic principles based on the primitive understanding of the basic nature of time, space, movement, energy, and power. If you compare the development of physics in the first three decades of the twentieth century to a symphony, one of the three main themes is: 1. Quantization (1900,
