当前，全社会呼唤加强素质教育，然而不少学校仍然存在着只重视理论知识而忽视对学生实验能力培养的现象。其重要原因之一是对实验在科学技术发展中的作用和地位理解不深。为此，本文结合物理学的发展史谈谈笔者的认识。l实验是产生物理学理论的源泉物理学是一门实验科学，物理 At present, the whole society calls for strengthening quality education. However, in many schools, there is still a phenomenon that only emphasizes theoretical knowledge and ignores the cultivation of students’ experimental abilities. One of the important reasons for this is the lack of understanding of the role and status of experiments in the development of science and technology. For this reason, this article discusses the author’s understanding in light of the history of the development of physics. l Experiment is the source of the theory of physics. Physics is an experimental science, physics
