本文为李政道教授在纪念中国国家自然科学基金十周年座谈会上的讲话,根据录音整理。经本人同意在本刊发表。—编者—今天,我很高兴能有机会参加纪念国家自然科学基金设立十周年座谈会。我们大家都知道,科学技术是第一生产力。我今天要讲的是:“没有今日的基础科学,就没有明日的科技应用”。为什么说没有今日的基础科学,就没有明日的科技应用?我可以举两个明确的例子来说明: 1.18世纪本·弗兰克林对电现象的重要发现,以及19世纪法拉弟有关电和磁的决定性实验,导致上世纪末麦克斯韦方程式,统一了电力和磁力,使我们理解光的本质及它和纯粹电磁现象的同一性。这一突破带来了发电机、电动机和电报、电视、雷达,以及全部现代化通讯手段。
This article is the speech of Professor Li Zhengdao at the Symposium to Commemorate the 10th Anniversary of China National Natural Science Foundation, according to the recording. With my consent in this publication. - Editor - Today, I am pleased to have the chance to attend the symposium to commemorate the 10th anniversary of the establishment of the National Natural Science Foundation. We all know that science and technology are primary productive forces. What I am trying to say today is: “Without today's basic science, there will be no future application of science and technology.” Why can not there be no tomorrow's application of science and technology without today's basic science? Let me give two clear examples: 1. Benjamin Franklin's major discovery of the phenomenon of electricity in the 18th century; and Fratlab's decisiveness of electricity and magnetism in the 19th century The experiment, which led to the Maxwell equations at the end of the last century, unifies electricity and magnetism, allows us to understand the nature of light and its identity with purely electromagnetic phenomena. This breakthrough brought generators, motors and cables, television, radar, and all modern means of communication.
