物理学最初被称为自然科学 ,随着科学研究和科学技术的深入发展 ,分化为化学、生物、天文、物理等学科 ,单独成为自然科学的一个分支 .物理学源于自然 ,同样也要回归自然 .在物理学的教学中要紧紧把握这一点 ,特别是应用物理部分 ,更应该把从大自然中获得的知识再应用于大自然 Physics was originally called the natural sciences. With the in-depth development of scientific research and science and technology, it has been divided into disciplines such as chemistry, biology, astronomy, and physics. It has become a branch of natural science alone. Physics originates from nature, and it also has to return. Naturally, we must firmly grasp this point in the teaching of physics, especially the applied physics part, we should apply the knowledge acquired from nature to nature again.
